This is the eleventh deer I've taken with the 450BM in addition to a couple black bears. All of them were taken with 250gr FTX bullets over LilGun. The shots ranged from 20 to 150 yards and all of them were one shot kills. Nothing has made it more than about 50 yards after being hit.
I'm a fan of the FTX bullet. I've taken more than a dozen deer with the 250gr FTX bullet in Harvester Crushed Rib Sabots in my CVA .50 muzzleloader since 2013 with 100gr Blackhorn 209. From 1700fps on up to 2200fps, the 250gr FTX has never let me down and has proven to be quite accurate.
