I bought the FPB and zero'd at 50 yds. Shot clean at the range. Probably a 2- 3 inch group using open sights and understand with open sights the gun (TC) outperformed the shooter. Shot two mature mule deer (both bucks); one at 30 and one at 50 yds.
The deer were dispatched as advertised. Bullet works exceedingly well and passed thru on both animals.
I wish I could have sent one of the bullets thru an elk, to give you (and me) more information on penetration of larger game.
I used 100 Grains of 777.
hope this helps
