75 yds. ( indoor range )

I will post the chrony work and the testing of the NSA 348 knurled BTHPs, 400 gr BTHP and someGriffin Ammo, (bthp 350gr) once completed.

I should be hitting the indoor 100yd range this coming weekend to try some different ammo and a new scope. In the line up is NSA 348gr knurled BTHP ( i know these perform very well, hogs be dammed!) 400gr BTHP, and also some Griffin ammo. I will be sure to post the results!

I am at similar point with AirForce .457 LSS CF. I am interested to see your results at 100 YD.

I’ve got one of these on the way, should be here Monday. I like the looks of that accuracy. I’ve shot several Texans and am just not a fan of the ergonomics...looking forward to giving this thing a run. I’m primarily a hunter, and this will be my first seriously powered big bore. I’ve had a 70-45 for about a year and it shoots good...I’ve taken a couple of deer and several coyotes with it. It gets the job done, but at 750fps with lighter bullets, the trajectory is pretty loopy.
