      Just got a new toy in from Simpson’s ltd.

      It’s a Husqvarna M46 small ring Mauser in 9.3x57mm . There was another thread on here last week and it was just too tempting to not get one.
      It showed up with stickers on the stock and some old oil residue builtup on all of the metal work. The barrel cleaned up with about 5 patches of no. 9 and the rifling looks crisp and sharp. After scrubbing the barrel out, I did a chamber cast to see what size bullet mold I needed to get. The throat is .3695″ and very long .565″ . The bore is .356x.368″, so I’m guessing at a .369 or .370″ mold diameter?
      All of the chamber and throat is way oversized. The chamber is about .010″ over the actual measured cases. I started a Speer 270 backwards and tried to chamber it. It went all the way in without touching the lands. Just barely seated forwards and at 3.335″ will chamber easily. About the max that will fit in the magazine is 3.220″.
      I’m going to go with Accurates 37-250B. Quickload thinks I should be able to get 2400fps out of it. I’ll start low and stop when I get good accuracy.
      Finding loading dies was a real pain. Graff’s had 1 set of RCBS dies for about 3x what Hornady has them listed for, but couldn’t find Hornady dies anywhere. I even called the company and they refered me back to Graff’s, lol.
      I’ve ordred a bunch of brass, some Norma 9.3×57 and a bag of Prvi 8×57(much cheaper) to neck up. When the dies get here, I’m going to see if I can form some out of 30-06 brass. I also found some Speer 270’s just incase the cast boolits don’t want to shoot with that .565″ freebore.

      The gun came with some weird scope with dead batteries. I’ll have to see if I can find some replacements somewhere and see if it still works.

      This appears to be one of their better grade of rifles that you were able to buy. Probably something not visible to the everyday customer. Simpsons Ltd. South Seminary St. in Galesburg Illinois. The gun store with over 3000 firearms on their show room floor, that many more in the back of the show room, even more than that many in the basement. The reason you had to clean the rifle was that the owners will not hire anyone to even wipe down the hundreds of rifles shipped in monthly. I have applied for just that job many times there and told that they would not waste the money to pay someone to do this even if it meant selling more firearms. I have seen rifles with bores so dirty you couldn’t see the rifling. Love to go in and look around but won’t buy thing unless I can literally steal it from them for the price.

      Thanks for the links on the batteries.
      Now that it’s cleaned up, the action is very smooth. I checked the twist rate and it’s 14″.
      I trimmed some 30-06 cases back and they formed just fine with one pass through the sizer. The necks are a little thicker, but with the generous chamber, I think that might actually help.

      Lar45, I have found that PPU brass is some of the thickest out thar,

      If you have a few try forming with them it should help even further to take up the space in the Chamber.

      I might be able to find 5 if you would like to try them.

      I picked up a bag of 100 8×57 PPU cases. They gave higher velocities than the Norma 9.3×57 brass.
      I started with 51gns of CFE223 with the Speer 270 loaded to 3.050″. Quickload showed that it should have given 2300fps, but it barely got 2000fps.
      I wonder if this is because of the masive .565″ of freebore? In Quickload, I put in for 3.60″ for a loaded length and it showed around 2000fps.
      The ol girl shot pretty good for me shooting offhand at 25yds. I just wanted to make sure that I was going to be on paper before I moved back to the bench. It looks like I’ll have to drift the rear sight a little bit.

      I am watching this with keen interest. With your dimensions for cast would a lee 375 mold size down and give you a slug to pc?

      I hadn’t thought of using the lee 375-250 mold, but it’s a good idea. I think the last one I had dropped at .377″. So going to .369 would be going aways down. I”m going to have to get a custom sizer made. If anybody has the 375 Lee mold, I would love to have a few boolits to play with. 🙂

      Doc 44 and I got out and shot the ol girls today getting a little more chronograph data.
      I’ve been comparing what little published data I can find with Quickload to try and get an idea of where to go and still be safe. I’ve got the Norma Data, but only have the Speer 270gn bullets, and don’t have any Norma powders on hand.
      The strange thing is that the actual velocities are much less than what Quickload predicted. I think that this might have something to do with the .565″ of freebore the bullet has to go through until it engages the rifling.
      The only powder I’ve tried so far is CFE223: Everything below is not published load data:
      Charge Quickload Actual
      51gn 2305 2022
      53gn 2394 2108
      55gn 2482 2206
      56gn 2527 2242

      I think I’ll try some RL-17 next to see if it still acts the same way.

      I found a great thread here: http://thehunterslife.com/forums/arc…p?t-12498.html
      From reading it, H4895 seems to be the way to go.
      These guys rifles also have the huge freebore, so that must have been a Husqvarna design for whatever reason.

      I browse Simspon’s daily and I saw those rifles. Just had no need, but I must say the prices were right. Nice rifle.

      The 9.3×57 has always intriged me and I’ve only seen one up until I read about the other poster’s rifle and then ordered these 2 for Doc and myself.

      I got out today and shot some with RL-17, with the 270 Speer loaded to 3.05″
      Charge, Quickload, Actual
      53gn , 2303 , 2087
      55gn , 2399 , 2229
      56gn , 2447 , 2270
      57gn , 2494 , 2298
      The 56 and 57gn loads finally had clean necks without any soot on them.
      All of the primers had rounded edges on them.
      The 56gn load started to have the body expand near the base, but the shoulder was still rounded, so I think the pressures are still low and in the safe zone.
      I think that I could live with the 57gn load at 2300fps.

      I started a thread in the reloading section asking about the freebore and have this posted there also. Sorry about the double posting, but I thought I should keep the chrony results together.
      I got some shooting in yesterday with H4895 and the Speer 270s.
      Charge, Quickload, Actual
      50gn, 2426fps, 2379fps
      52gn, 2514fps, 2432fps
      54gn, 2601fps, 2470fps
      The H4895 seemed to have much less variance from Quickload than the other powders I’ve tried so far.
      I think I’ll stay with the 52gn load. The shoulder is just starting to fireform completely and the primers all have rounded edges, so I think I’m still in the safe zone.
      I’ve been reading everything I could find on the 9.3×57 and the Husqvarna 46, and it seems like the round was chambered in a Manlicher rifle as well as the Swede M96. I’m wondering if the Manlicher was a weaker action and that’s why the pressures for the round were kept to 43kpsi? I did not find any reference as to which Manlicher rifle it was chambered in.

      We loaded and shot some of the Norma 9.3×57 and the primers backed out. I bought some PPU 8×57 and ran it through the sizer die, all of those acted normally.
      So I took a closer look and the Norma stuff looked like the shoulder was farther back. So I ran it through a .416 expander, then through the 9.3 sizer die and got a nice tight fit.
      The fired PPU case held 66.5gns H2O, Quickload shows 63gns

      From left to right is a reformed Norma case, a stock Norma case and a PPU 8×57 necked up.

      I measured a fired case and came up with 66.5gns H2O vs. Quickload says 63gns. The barrels on our rifles are also over sized mine is a M46A and the barrel is a 4 groove .368″ and Doc’s M46 is at .371″ with 6 grooves. The throats on both are .371″ @ .565″ long. So I made 2 new cartridge files in Quickload with the bigger case capacity and the larger “cross sectionable bore area”. The cases are a little shorter so i put that length is Quickload also.
      The Quickload bore area for the 9.3×57 is .102796, the .368″ is .103004, and the .371 is .105241
      The Quickload results are getting very close to the chronoed velocity.
      Speer 270 with H4895, COAL 3.050″
      Charge-Quickload-measured
      50gns – 2370fps – 2379fps
      51gns – 2413fps – 2422fps
      52gns – 2455fps – 2432fps
      The only thing that I haven’t figured out yet is how to account for the .565″ of freebore. My guess is that it may be the “Shot Start (Initiation) Pressure” The bullet should have almost no resistance to start moving other than the neck tension.
      I should probably just leave it as is.
      I’ve got some bullet sizers coming from NOE and we are going to try some lighter .375″ jacketed bullets sized down to .368″ and .371″ and see what happens. I also have some .375″ cast bullets to try as well. I’ll size them to .371″ to fit the throat and see if we can get any useable accuracy. I would probably shoot it more if I can get a good cast load worked up.

      I got some shooting in yesterday with the Hunter’s Supply .375″ 265. It’s a gas check bullet, but they sell them without it so I put some Gator 9.3s on and stuffed them through the .369″ and .367″ sizers from NOE. The bullets came out as .370″ and .368″. My bore is .368″, so I thought the .370″ bullets would work best, but the accuracy was all over the place. I tried the .368″ at a couple of different seating depths and shot the target below. The load was 20gn of 2400 with a WLR primer seated to 2.763″ and clocked 1491fps.
      Seating the .368 and .370″ bullets were bulging the necks to one side, so I took a .375″ expander button, put it in the drill and ground it down a little with a bench grinder, then polished it with some 400 W&D sandpaper.

      Now that the seating depth looks pretty good, I’ll try pushing up the velocity and see where it goes.

      I also shot some of the Speer 9.3 270’s with 51gns of H4895 seated to 3.05″ and are going 2422fps.

      This group doesn’t look wonderful, but it should work for pigs under 100yds.
      Doc44 picked up a few different .375″ bullets so we can try sizing them down. There is a much wider range of bullets in .375 than 9.3, plus with neither of our rifles having a .366″ bore, we are hoping that sizing some bullets for the correct groove size will give us something usable.

      Prowling Simpsons I spotted a nice Husky 640 in 9.3×62. I didn’t make the same mistake twice. This one is at my house. Some of your cast loads will likely be a good starting point for the 9.3×62.

      Is your’s built on a 98 action? Have you slugged your barrel yet to see what size it is? Just curious if they hit the .366″. My M46a is .368″ and Doc44’s M46 is .371″, and both with .565″ of freebore. It would be interesting to see what a chamber cast of your x62 would show.

      I second. It would be very interesting to see a chamber cast.

      I got to shoot Lar45’s rifle Sunday. What a treat! Totally enjoyable experience. I have a die set for 9.3X62 and someday, I want to build one. Great calibers, all the 9.3’s.

      • Our next bullet to try was the 200gn Sierras sized from .375 to .368″ in one of NOE’s cast bullet sizers. we tried H4895 and were not able to get much velocity from it.
        So we decided to try a modern powder, IMR4166, with a little slower burn rate.
        We started low and worked up to 54gns in Norma 9.3 brass in Doc’s rifle with the 200gn Sierra seated to 2.806″ gave us 2621 fps with a SD of 10.77.
        My rifle needed 55gns of 4166 in a PPU 8×57 case with the same COAL of 2.806″ gave me 2615fps with a SD of 14.57.
        Here’s the target, shot at my front door range of 85yds.


        The first round hit very high, so I cranked the scope down and over and fired the last 4 shots in that group. I think I’ll be happy with it and resist the urge to try and fine tune it further.

        One of Goodsteel’s friends has 3 boxes of Speer .375 235s that I’m going to trade lube with. I think these will be the next ones to try.

      Yes, it is a commercial FN 98 action. I will have to order some casting material and give it a shot. I have never made a chamber casting before.

      Tim did a nice writeup on doing a chamber cast, but I can’t seem to find it.
      found it.

      I traded for 3 boxes of Speer’s .375 235gn bullets from one of Tim’s friends. I gone through about 1/2 of the first box trying to find a good load. IMR 4166 was giving us the velocities that we were looking for, but the velocity range was very large, which I think gave us some large vertical stringing.
      I tried the same loads, but with a CCI mag primer this time and had much better results. It looks like 2450fps is about all we are going to get out of the 235 Speers and IMR4166.

      If you look close at the top right hole you can see it had 2 bullets go through it.

      The results aren’t as nice as the 200gn Seirras, but it looks useable.

      I stopped at Simpson’s the first week of May while on my way to Chicago. I was disappointed they only had a few of these rifles on display. They won’t let you go into the back and dig through the pile. You can use their computer to choose one, but it just ain’t the same a seeing it in person. They said there are a few in 9.3×64 also, but I didn’t see any. There were more in .30-06 than 9.3×57. I was still probably going to buy one until they said they would have to ship to a FFL dealer. Illinois has a law that they can only sell long guns to residents of Illinois or an adjoining state. I left in disgust. Additionally, they would not let me use the restroom, even though I was willing to buy a firearm. I do like the looks of some of the subject rifles.

      Sounds like very terrible customer service.
      You are right about holding it in your hand and seeing it in person. They have like 3 different views in there online cataloug, and that sometimes doesn’t cover everything that’s important.
      Wayne picked out a M46, and I got a M46A. When the rifles arrived here, I definatly like the looks of the M46 much better than the M46A. They are both very light and handy rifles weighing in just under 7#.
      I bought my rifle using there online catalog, They wanted my dealer to send a copy of their FFL, They shipped the rifles very quickly and we had them here in just a couple of days. The rifles were packed in lots of bubble wrap and the scopes were taken off and packaged separately.
      The rifles were dirty and needed a good cleaning inside and out.

      I tried H4895 with the .375 Speer 235’s, sized down to .369″, this weekend and had some good luck with it in my M46A.
      54gns gave me 2510fps and a 1.4″ 5shot group. I shot two more targets and got similar groups.

      We ended up with 53gns H4895 in Wayne’s M46 and got a 1.45″ group. A Quickload estimation of pressure should be around 52k psi. The primers all still had rounded edges and extraction was easy.
      I think we are done with Jacketed load development.

      We were useing Wayne’s H4895 for his loads and I bought some new powder for my loads. His load of 53gns gave 2569fps and my load of 54gns gave 2510fps.
      So we shot both his and mine at 54gns in my rifle to see what the difference was.
      His powder gave 2591fps and mine gave 2510fps. So I guess it’s true that you should back off 10% with a new can of powder and work back up to where you want to be.

      That’s very interesting about the powder. Are both modern production?

      They are both in the same black plastic bottle with the same label on them, only different lot numbers

      Wayne’s powder is on the left, and mine is on the right. I bought mine sometime this year.
