Found this one while grinding up some meat. Don't know what caliber maybe 25-06 ,looks like a fail safe bullet. What ever it is I'd say it's a piss poor design and choice for deer.
I think with the hornadys (which are great killers) if you hit a bone, shoulder etc they can sort of grenade a little, not quite like the exploding varmint rounds from a .204 but some.For those who complain about Hornady’s not opening, I would suggest that the are opening, and the mushroom is disappearing, with the copper jacket completely folding back. This bullet looks like little more than a round ball.
The reason is bolt thrust 5.56 the rim is .378" rated at 62,366 psi 223 Remington 55,000 psi....450 Bushmaster has a .473" rim rated at 38,500 psi....there's less metal left on the lugs locking the bolt 450 BM....there has been some problems with cracked or sheared lugs with the 6.8 SPC with a .422" rim because of its 58,700 psi maximum pressure....I'am sure there was a little "hot rodding" involved...I agree with this. The 450 could have saami spec'd this round for 55k psi, but didn't - certain there's a good reason. The AR15 can and does handle that amount of pressure - look at the spec for the 350 legend.
Bear Creek (nice guys- met them at the show yesterday) is loading the bullets long, so they don't fit in an AR mag. It's only a matter of time before someone single loads this into an AR.
If people want a high pressure 45 Cal, get the 45 raptor. Designed for 62K psi.
I know bolts can be loading higher but that was based on the assumption the brass is rated at 62,000 not 38,000 psi.In an AR. Bolt actions can be loaded higher
Ill show you the easiest way to do pics. Check your private messages for instructions.I have recovered 2 Barnes TSX 250 gr from my .45/70 shots. Data said about 2,200 fps. The first was a zebra at 105-110 yards angling towards me. Went in just inside the right shoulder and was found in the left hindquarter. It mushroomed perfectly to just under 7/8". It weighed 250.2 grains, perfectly clean. It went less than 100 yards. Second was a whitetail at about 15 yards from a tree stand about 10-12 feet up. It was facing me. The bullet entered the right shoulder, hitting the ball, breaking it into 5 pieces. It ricocheted directly across to the left shoulder, hitting that ball, breaking it into 3 pieces. It then turned 90 degrees and traveled up the neck, stopping a couple inches short of the jaw. It weighed 22o grains, was a near perfect mushroom and lost one petal. (We processed it ourselves and saw everything described.) It went about 15 feet. (If I can figure out how to post pics I'll put those two up.)
The pressures I stated is for the SAMMI specification of the cartridge not the brass itself....Are you saying the actual brass rim of 450 BM is rated at 38,500? Meaning independant of gun type (single shot, bolt, AR) the limiting factor is the brass itself?
We speak the same language. I'm an advanced reloader and fully understand the physics of BF diameter and lug abatement pressure. They should've done 2 saami specs.The reason is bolt thrust 5.56 the rim is .378" rated at 62,366 psi 223 Remington 55,000 psi....450 Bushmaster has a .473" rim rated at 38,500 psi....there's less metal left on the lugs locking the bolt 450 BM....there has been some problems with cracked or sheared lugs with the 6.8 SPC with a .422" rim because of its 58,700 psi maximum pressure....I'am sure there was a little "hot rodding" involved...
In a 450 BM in a bolt rifle 62,000 psi loads depending on the bullet you might gain 100-150 fps recoil will go from a 20 ga. push to a 12 ga single shot with a 3 1/2" mag load....
A partner of mine was commissioned to develop "Proof Loads" for a custom bolt action rifle maker they are 72,000 psi loads....at 62,000 psi primers were flat and slight cratering....at 72,000 psi bolt was hard to lift....we even pushed a couple to 80,000 psi a rubber mallet needed to be used to get the bolt open the cases had a slight ring above the base the start of case heads separation....
Probably does not for most the shots taken.To certain degree, most of this is an academic conversation. Does an additional 100-500 fps make a real difference in terminal ballistics at the distances we shoot?

Bet you don't by retrieve many of those even in such a low sectional density bullet.
