FMJ can work on lungs. Other times it doesn't do so good. Slow twists help it tumble when it hits.
Some FMJ come apart at the cannelure as noted.
Do not expect accuracy from any FMJ round. Its by far the worst ammo you can get for accuracy.
As a side note about 30 minutes ago a friend called. Pigs on neighbors oats. 52 bthp at the back of the ribs was the only shot I could get in a hurry. I was wanting the big boar gone but you take what you can get on pigs... He fell about 50 yards into the thorns and vines. 30 yard shot. Suppressed bolt gun and you could hear the HP hit hard.
I paid $9.99 a box for the PMC haven't even shot the gun yet,range is 25 miles from home haven't got there yet. also have 3 boxes of Armscor .223 55 gr fmj bought those when I bought gun.
