      Just loaded some of these with Varget and Rel 15 to try in our Savage Model 12 rifles.
      We will test them at 200 yds.
      I would prefer 300 but right now we have a shooting bench set up for 200.

      I was thinking of rebarreling the Savage with a Krieger barrel in a 1:12 twist.

      My UPS man is a competitor and has $3000 race guns.
      He said “No man you want a 1:10”

      I didn’t want to argue with him so I just listened and smiled.

      Most all my shooting will be out to 600 yds
      Maybe occasionally 1000 , but that would be rare.

      Personally, I would go no slower than 1-11.
      1-12 is going to be only marginally stable.
      You can jump on Berger’s twist rate calculator and punch up the numbers easily.
      http://www.bergerbullets.com/twist-rate-calculator/

      The 185 Juggernaut has a OAL of 1.344″.
      Given that OAL, and the speed of the 308 Winchester at 2650 and a twist rate of 1-12, you get a SG value of 1.33.
      You really want 1.5 or higher. This has to do with bullet length, not weight.

      Conversely, a Sierra 180 grain Match King has a bullet length of 1.277 and exhibits a SG value of 1.54 which is perfectly stable.

      By the same token, if you stick with the 185 Juggernaut, but go with a twist rate of 1-11, your SG value goes up to 1.58.
      However, if you were to take your mailman’s advice and go with the 1-10 twist, you’d be at a SG of 1.91 which gives a LOT more room to breath with not a thought one of bullet RPM degradation at long range (1000 yards).

      If I were building a rifle for your stated range of 300 yards, with the juggernaut in mind as the primary projectile, with no plans to shoot longer projectiles, I would go no slower than 1-11 and take a 1-10 if it was easier to get (which it will be).

      I:11 would be a great choice.
      Unless I get great performance from the Juggernaut, I will most likely be shooing the Sierra 175 MK.
      They are cheaper, and I already have about 1500 of them in stock.

      Oddly enough so far my Savage has shown a preference for the Sierra 168 MK.

      My son’s Savage has a better barrel on it than mine.
      His is chrome moly steel and mine is stainless.
      More visible tool marks in mine.

      His clearly shoots better no matter which gun He shoots.

      The Sierra 168 MK bullet was designed from the outset for 300 meter international competition. The fact that it does so well in National Match competition and at 600 yards is a bonus.

      My Win Model 70 shoot the 168 or 175 well.
      My Steyr Tactical like the 168

      Both guns have 1:12 twist and are half inch rifles.

      I’ve said it before and I’ll say it again. With 1-12 twist, 168 grain hornady or sierra bullets is my go to. Sure the 12 twist will stabilize the 175, but the 168 is just plug and play.
      I step up to 175s for shooting 10 twist barrels.

      My son got these Berger 185’s to shoot 1/2MOA at 200 yds using 41.6 grs of Varget ,CCI BR primer and Nosler brass.
      I am going to load some more and test this load out thoroughly in his rifle ,but it is the best we have found so far.
