Thread: Sub 20 inch .223 barrels. Who's running them?

Cool, thanks for that. I clearly have a slow barrel because I'm running more BM2 than that out of a 22 inch tube and only getting marginally faster speeds

General consensus seems to be to chop it so I sent it off to the gunsmith this afternoon.

Cheers all.

I think you will like it.... a bit late if you don't

It will be interesting to run your load down your shortened barrel to see what speed you get then?

Yeh I don't know if it's a fast barrel or what. I'm getting 3015 f/sec with the 75gr A Max using 25.8gr BM2, which I think is pretty fast too.

Is that with a standard .223??!?!! How's your pressure? Because that's getting towards max (Ie blown primers type max was 3100) with 20" .223AI

No this is not a standard .223............... It's a T3
No real sign of pressure at that. Primers look fine, maybe a little flat. I've only done a ladder test at this stage so I'll go and re prime them and see if they have loosened up.
