Well I would like to report on powerbelt effectiveness since there seems to be question about this bullet. My buddy shot a doe on Saturday at about 60 yards with a 100 grain charge of Pyrodex pellets. The bullet entered high on the back (loss 1 loin) broke through about 7 ribs, went through a lung, and lodged in the neck. The entrance hole was the size of a fist. The deer didn't move an inch and just fell over. The bullet was found in the neck, and just an estimate, the 295 grain bullet ended up at around 130 grains. The piece I found was the bottom of the bullet and it was only about .65-.70 inches around.

Sounds to me like it did the job!

Also sounds like the doe was shot from a tree at about 15-30yds?

Well, it sure did the job. It lost alot of weight, but it figures after shredding 7 ribs. Its wasn't a short shot, probably 50 yards. But it was my buddy's first deer, most likely nerves I think.

Hope they knock em down like that for me this season

See my reply to Scoutcam. Our experience has been the 245's are great on paper, but lousy on deer. I know every shot is different.
Shots were at 75-80 yards from a permanent stand. NO BLOOD.

245 gr. 50 cal hp
75 yrd shot tops
entry hole about size of bullet
exit hole about 2"
double lung shot
ran 25 yds.
unbelievable blood trail (not that I needed it for a 25 yrd track job)
I think they work just fine

My buddy used them on his buck, in our early muzleloading season. I think he was using the 295 grain. He shot the buck at 40 yards, deer ran about another 30. It seemed to do the job, but we noticed that the exit wound was about the same size as the bullet, seemed like little or no expansion. Hard to judge with just one shot, but that's what we found.
