Short Barreled 280AI

[Ikmclean]

Are you using a short or long action? What powder are you using?

The 284 is intriguing if it can be done on a true short action. SAAMI spec is 2.8" OAL but with Hawkins hunter mags you can seat your bullets out a bit longer (2.98"max). It uses less powder (and I would think less recoil as well), standard primers, and more mag capacity than a 7saum.

51.5 grains H4350, 3.100" oal

I'm 2 grains below max on Hodgdon, they list 2.970oal

Keep us posted. Are you shooting factory ammo or planning to load for it?

I have a savage 7mm-08 that has been cut to 16” and shoot suppressed. It is shooting factory 150 gr precision hunter between 2650 - 2700 fps.

This^^^^ My 08 load 150gr is at 2840,20 in bbl. I have a 280 ai 24" still messing with a load for it. With the lower velocities on the sb 280, might as well stay with the 08 for sure.

I cut my 280AI from 22" to 18". 162ELDMs dropped from 2840 to 2720 using a modest load of H4831SC.

This is what i was thinking i would get. Didn't get a chance this weekend to shoot, but if i get these numbers, im happy!

Finally got a chance to shoot this rifle. Used done factory ammo and reloads.
Factory 160 patition shot at roughly 2650 fps
Factory 162 eldx precision hunter was 2550 fps.

Reloads modest powder with staball 155 terminal ascents were roughly 2800 fps. May be able to pish more, but wanted 2750+ so probably not going to push it.
Reloads with modest powder h4831sc 155 terminal ascent was much slower. Heaviest load reached just shy of 2700 fps.
Must say i love sitting this gun so far. Will keep working on it when i have time.
