Just picked up a box of the Hornady 75 HPBT for my 1:9 223. Are you guys getting better results from them jumping , on the lands or jambing them? Looking to work a load for 500 yards.

Thanks
Danley

Seating depth - 2.355 was where I stopped based on grouping. Kissing the lands.

Bullets - tried several different ones, but stuck with Hornady 75 BTHP (Self Moly'd). These have actually printed a 2 inch group at 550 yards. I use this rifle for Mid Range F Class.

Brass - RP with vel average at 2950

Powder - RL 15 (25.5 - please work up to it.......)

Primers - RP 7.5's.

Thanks for the info. I`ve got several different loads loaded for this weekend with them (.010 off ... to on the lands). I hope that they do better than the A-Maxes at the longer ranges. They shoot great at shorter range but at distance they get very inconsistant.
