We/I have used nearly 99% of all the bullets listed above. I have as well experienced problems listed with the XTP's. I shoot a knight Disc Extreme 50cal. My brother shoots a T/C. We have came down to the past few years on using the SST's and now this past year and now, we are using the Hornady 225grn FTX, 45 cal. My brother has shot 7 deer with all but one dropping in its tracks, out to distances of 181 yds. The one that moved only went less than 10yds. All had exit wounds of nearly the size of a quarter. I just shot a big bodied buck this past friday AM with my 460 shooting the same projectile. Stood him up like a stallion, head reared back and up as far as it would go to only flip over, no twitch, no kick. I hit him in the brisket as he was facing me at 60yds. Blew a hole the size of your fist out of the brisket and exited just behind the right shoulder. He shoots the same bullet with a black harvester sabot over 110grn T7. He took a 300lb hog last year with it through both gristle plates and exited. And they are $35 for 100!!!
