I've had the same experience with powerbelts. 5 deer shot, 3 of them Drt, the other 2 ran about 40 yds with no blood whatsoever. Not one bullet passed all the way through on any of the 5 deer. I was using 100 gr.( 2 pellets) and the 245 AT's. I did not know that 100 grains was too much until I read comments on these forums. If you ask me the pamphlet that comes with the powerbelts should state the CORRECT recommended load. The pamphlet says 110 to 150 gr.s of pyrodex pellets recommended for .50 cal. magnum rifles. They should be suggesting the 80 or 90 charge load and helping out the hunter using them. I don't use them anymore. I use Barnes and Gold dots and have a lot more confidence in these bullets. I don't want to use any bullet that I have to worry about fragmenting on impact. If you ask me it's a fussy bullet.
