280 AI 175 Elite Hunter Loads

Interesting as in my saum gm210 are noticeably better than gm215’s with R26.

Its why always test different primers

Mine shoots one hole groups with both RL-22 & IMR 7828 with 168gr Berger VLD Hunting & Target 2800 fps Norma Brass.

I am using H4831sc powder with a Berger 175gr. In my 280AI 1@8 26-inch barrel. I am getting 2900+ fps. But I'm little over max. 4 shot groups. I thought i had loaded up 5 rds of each load. But didnt. N560 would be worth a try.

I’m using 4831sc in my 280AI with Peterson brass but keeping it at just over 2’800 to keep from destroying the primer pockets..
I would suggest that much like the 7PRCW that driving them faster than 2’850 is asking for “clickers” and short brass life.
Getting the Berger 184’s moving with 56.7gr of the 4831 though next load I will see what a tenth or two more will give… 57.2gr definitely gave pressure signs and I did not have it chronographed for those few shots but suspect 2’900 or close.
Any clickers will be dealt with my rollsizer as the brass already get a session through it after cleaning and annealing @ time before being re-loaded.
At this point cases are still good after 6 reloads.
