As propellants are either/and nitroglycerin or nitrocellulose – both which destabilize(outgas) an acidic compound, our ethylene/glycol based PC deteriorates. The slow (double based) powders typically have more stabilizers added ( reduced outgassing) therefore the effect is less pronounced. Solution? Switch to Hitek, use a paper GC, wipe the base…[Read more]
FTX is harder jacket than Amax but still has the BT. Have you looked at 170 interlock? Flat base and fills the throat well. BC is poop but hey, short distance anyway. The reason I went with the RD style for the pistol. Used a 185GC version (softer alloy) on a sprinting pig. I did find blood on a johnson grass blade – took a shot ~50 and f…[Read more]
170gr RD style PB @ ~ 1650. 18″ carbine (50 yds), short pistol will be ~10% slower. 17gr CFE blk or 1680. Rested on a bag and me on the back. More space in there but haven’t tried for faster yet. Primer pockets are still good. H110 seems to run out of steam ~ 170gr.
First, only vapors burn. Lube will liquefy (and expand) and flow from pressure. As the liquid flows to the base it builds up at the GC dam and exerts pressure on the alloy, compressing it. Larry G. has noted the recovered cast are smaller than bore due to the in-compressibily of the liquid lube – same happens at the base/GC.
Attended the security seminar last nite. Training in attitude and response from an ex-marine security type that does big event protection details. Lots of credentials. Lots of real info vs the media hype. Lots of firsthand analysis/comments on active shooter situations. His biggest complaint is cellphones. Calls them the white state (con…[Read more]
Guns in a safe is ridiculous. Real controlled building access for EVERYBODY. I watched 12:15 Paris. One scene was silly. Active shooter accidental alarm. Class lockdown and everybody gets under the desk. Closed classroom is a killing field! If a shooter gets in the room, attack and throw anything at the guy. Gun can’t hit everybody at once…[Read more]
Very well put. I will add that most schools and public places were NOT designed with ANY security in mind. Also, most school admin are ‘privileged’ and ‘educated’ people. Yes, there are heroic people in schools that try to protect the kids, after the fact. A few are beginning to realize the situation they are in. There is an attempt to restr…[Read more]
Nope, one 7mm from a few years back and my friend did the others with my carbine. He ranged for me (never shot the 308 before), then I did 3 shots. I think he was bored driving the 4×4 down to reset the target. Next time I’ll take the 24″ upper and try 400. Dang, took the scope off it cause the GK said he might want it. Too heavy. So got to s…[Read more]
