280 AI

[280aiyote]

26 is better barrel length for 280ai in my eyes, but fireforminf doesn't take as long once you get it down.

I'll jump in since I got my 280ai with a 24" tube and I've been working up loads for it this summer. 160gr. AB with a pretty hot charge of 7828ssc nets just under 3080 with tight(to me) sd and es. Retumbo is a little slower in my gun.

I've never tried reloader brand powders but after reading a lot on here if like to give rl22 a go in this gun.

RL26 will likely give you more velocity than 22.

Don't do RL22, try RL23. Much more temp stable.

Ok thanks. I need to read up on their number system and better understand their burn rates and temp sensitivity.

sorry op not trying to hijack your thread!

ah you posted this as I was replying to elkaholic but temp sensitivity is my main concern with RL powders.

I agree on 23 for temp. Won't get quite the velocity of 26 but better where temp is an issue.

Gunworks here in NZ is advertising Norma 280 AI brass. It may be a miss print but they say they have Norma and Nosler.
www.gunworks.co.nz
It may pay to be seated before you see the price.

Considering Norma makes Nosler brass, I see no difference between the two other than Nosler actually weight sorting theory headstamped brass a bit more consistently. Same soft head in both however in all other cases I have used.

You can always fire form any other .280 Rem or .270 Win brass into .280AI.

Nosler makes the 280ai brass. Norma does make some of the Nosler brass but not the 280 stuff.

I have only ever used the Nosler brass in my Ackley, but my experience has been good. Its no Lapua but has held up well. I'm 6 firings in on 100 cases and primer pockets are still GTG.

Mine sports a 22" Brux that is shot suppressed 100% of the time.

With RL-26 I get right at 2950 with the 160 Accubond. With H4831sc, I get around 2825. Accuracy is superb with both.

RL-23, Retumbo, H1000, and IMR 7828ssc sure seem to be viable options too.

Following. Still trying to work my way through 300 rounds of factory Norma...

Good thing is the factory shoots 1/2 moa at 100.

Favorite load with my 23" brux barrel is 180 VLD loaded with 58 grains of 4831SC is 2869fps.

There's another company, Quality Cartridge https://www.qual-cart.com/index.html . Looks like they wait for orders then make a run of brass. I have no idea to the "quality" of Quality Cartridge.
Has anybody else have any experience with any of the stuff in any cartridge?
