280 AI 175 Elite Hunter Loads

[L.Sherm]

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.

Vihtavuori 280Al 175gr load data shows 58.5 gr max with H4831sc . I have friends using 59.4 with a Berger 175gr in there 280AI rifle. I dont shoot mine much. The way it groups. With that load. I took a few Nosler and Hornady 280AI once fired brass. On my 4th firing . Still good primer pockets. A total of 5 firing.

Try some Lapua 30/06 brass, tough is an understatement.

With 175s, I shoot 56g of IMR 7828 and the Federal 210 is the primer that puts them all in a hole.

How do I turn it into 280AI brass? I have the RCBS 2 piece 280AI die set. Redding 3 piece 280Al die set. And a set of LEE 2 piece 280AI die set. (Not SAAMI spec). I have Norma 30 06 brass. I took new old stock Remington 280 rem brass fired forum them. I dont have a way to heat my brass up.

Lube the neck and shoulder of the Lapua brass. With the full length sizer set to headspace the 280 brass properly, just run the Lapua brass through the full-length sizer.

As an aid, put a heavy chamfer on the outside of the case mouth of the '06 brass.

I fire form the '06 brass to AI by firing 15.0g of bullseye, and filling the case full of cream of wheat, put a tiny piece of paper towel in the case mouth...the case comes out 98% fully formed, and you will have incredible accuracy.

Peterson is pretty good brass, but Norma is soft, and you will not be able to reach peak pressure where the accuracy is great without losing primer pockets with the Norma.

Check the Over All Length of the cases.

This job is a no brainer, and that is an understatement. If you ever find any old Lake City Match brass in '06, buy it if it is new, the stuff is as tough as Lapua.

Best wishes

Got new backordered chrono a few weeks ago. 280 AI, 2950 fps. with RL 23, 175 Elite Hunter and 24" barrel. This is at 1.6gr below Berger provided max. Backed down another gr and went to 2870ish fps. Was amazed and checked load with someone else's chrono. Same result. This must be the most efficient cartridge/powder/bullet combo in shooting. Or is still a little hot......

Just goes to show you each gun is different and Cartridge.

Its not hot, it might be warm but ive done it in 3 with fireformed R-P 280 brass an PP were still tight.
Run it were it shoots if its not killing brass.

Saum is a short fat case though.
