Short barrel 280 Ackley

[AKdan]

Hey guys,

I bought a lightweight 280 AI and am going to send it off to be threaded for a suppressor. Before I do I was thinking about trimming it down a little from 24" to make it a little handier and to have less deflection with the suppressor. I am not concerned with a little velocity loss but wondering what you guys think would be the best length. I was debating 21"-22".

Thoughts?

Thanks
Dan

Just built one with a 22" barrel myself with the plan of using suppressed, still waiting on the can.

Balances nice. I'm getting 2925-2950 with the 162 ELDx and RL-26.

Thanks for the reply. That is exactly what I was looking for. I plan to shoot the 162 eld-x. I was hoping to get 2900 FPS.

Can you tell me what a light weight jacket is? Auto correct or a brand name or smith?
My .280 AI just came yesterday!! We ended up at 21.5 and it seems really good balance wise. #4 Lilja fluted on a m70 pre-64. It isn't any fly weight but I have a few filling that nitch already.

Ha ha sorry, it was an autocorrect, I should proofread a little better. I think I am going to give 22" a try. Going to send the rifle off in the next day or two.

I had one that originally had a 27'' lilia on it. Thought it was way too long for a hunting rig, took it down to 19". Load was cci br2, 60.5gr of retumbo. Shooting the 162 eld-x at 2950 with the 27" then dropped to 2750 by taking 8" off the barrel.

Its a few years later but how are the results? I recently had a 280AI built with a 22" 1-10 twist barrel, went short because I wanted to run it suppressed also.

Kinda curious why go with an 'Improved' case to hold more powder if the barrel is shortened so much it can't burn the extra powder filling that AI case?

Because it's still faster than a standard 280?
