Thread: FMJ on animals

Um, the chances of a jacket being left in the barrel is an almost comical idea to me, I have great difficulty believing it. Also I dont think lead is poured in but swagged (pressed) in.

The weakest bullets you are going to get will be cast lead, so taking off the copper jacket of an FMJ at the tip where it sees less force of the spin but leaving the main body shouldnt be an issue.

On top of that a good FMJ that is designed to break up by tumbling, well it just seems casually altering it to remove this capability, odd.

Go find an old gunsmith and ask him, When I first started shooting I used to hang out at the local gunshop quite a lot the gunsmith that owned it was ex army and had a stack of .303 barrels
taken of old stuffed Le Enfield's a good number of them had jackets stuck in them, a .303 has 45000 psi pressure when fired so a lead plug is not going to stop it, the lead core is swaged into the jacket
not bonded, as lead is soft and slippery compared to the jacket it will part company with the jacket leaving it in the barrel, FMJ's are not designed to break up that just happens some times go to any range
and you will find FMJ's intact most of them will be bent like bananas the broken up ones are ricochets thats where the tumbling bullets come from not from hitting flesh, any bullet so unstable that it tumbles
on impact is not any use it won't fly straight or penetrate far enough the military is all about putting holes through things if the projectiles break up on light cover they are not of much use,
Also cast lead bullets are harder than the cores of FMJ's bullets general they are pure lead as it is easy to swage into the jackets, soft point bullet cores are some what harder usually 3% antinomy
is added to pure lead to slow expansion, where a cast bullet is made up of 92% lead 6% antimony 2% tin, If you want cheap bullets use cast ones as long as there are wheel weights and lead flashings
available there will be plenty of cheap bullets,This is what a cast bullet will do if you get it wrong
