280 ai

[varmit_master]

Alot of good information on here. I have a new Browning rifle. A Xbolt Hells Canyon Speed Long Range 280AI. It has a 1@8 twist 26-inch flutted barrel. I have bought up several different bullets to try. Hoping it will like the ELD X 175gr. Or the ELD M 180 gr. Powders i have on hand.

Imr 7828ssc
Imr 4831
H4831 sc
RL 22
RL19
Ramshot magnum
Hopefully have some H1000 coming.

Using new nosler 280AI brass. And Federal 210 M primers. Any suggestion?

Starting my 280AI journey next weekend. I purchased a custom HOWA 1500 from a rifle builder I know. It has a 26" heavy profile barrel set into a B&C stock. He let me know that he was getting SUB MOA from 175 Berger Elite Hunters with RL-21. Well, cannot find that powder anywhere. I reached out to Berger and got their load info and I have some N-565 in my stash. So, I am ladder testing with that powder. I also have some 160 Nosler ABs that I will be trying with RL-19. Been doing a lot of reading here and I am thinking I need to snatch up some H4831SC.

I suspect he meant RL23 as it works great in the 280ai as I have several loads worked up with that powder. H4831sc works great as well but will give up some speed vs RL23

It may have been. I decided to see what the N565 will do before I buy any other powders. Heat has been horrible, so I haven't gotten to the range. This weekend looks to be better, so I will be doing some ladder testing.

7828 SSC will probably net you the best case fill, velocity, and stability. Just from my experiences.

I bought 5 cans of IMR 7828ssc. Just for the 280AI.
