Got a question or answer?
Log in to participate
Does this ammo work in the Texan LSS 50 cal?
These are meant for the Texans and Hammers, yes
Would these be ok for deer in a Dragon claw at 35 yards or closer?
This does not fit in the Dragon Claw. I found out the hard way and ruined a hunting trip.
The 420 grains are a bit heavy for the Dragon Claw a 300-325 grain would shoot better.

As the owner of a 50 caliber Hatsan PileDriver air rifle, I wanted large, heavy projectiles for big game hunting - deer and feral hogs. My preferred load for hogs in the past was a 330gr hard cast lead bullet pushed at around 2,000 fps. This bullet shot from the big PCP air rifle gives approximately the same performance, and should be a dependable hog stopper. I use a suppressor on my .44, and the air gun suppressor I mounted to my Hatsan should make it just as quiet.
Things I would have changed:Nothing, so far.
