150 grainsof powder and a 245 or 295 grain powerbelt will NOT blow up with a lung shot. It may on a shoulder shot but i do not take those kind of shots and never will.

150 grains loose pyrodex rs- 295 aerotip powerbelt - 148 yard shot on mule deer doe - Entered cleanly and exited with a 1" clean hole. Slid 4 feet and was dead.

120 grains loose pyrodex rs- 245 hollow point powerbelt- 146 yard shot, neckshot, dead deer and entered right infront of the neck/chest , exited just infront of the shoulder area.

My brothers load:
90 grains RS, 295 aerotip, 100 yards, high spine shot that put it down temporarily put it down until she got her back inplace, stood up, #2 shot with the same load went through both lungs and exited, deer dropped dead in its tracks.

Dads deer:
90 grains rs, 295 aerotip, bullet hit the deer in the collar bone, exited in the lower chest/neck area, dead deer. Dang tasty one too!

I like lung shots, it puts them down a lot faster, bleeds them out and makes gutting a lot cleaner. Why take a chance putting a bullet through the shoulder when a lung shot is guaranteed to put it down a lot faster?

Powerbelts are capable of taking game with 150 grains of powder with the right shots.
