Re: What is the longest COAL a .308 can have?
Depends on the mag, too. There's stuff somewhere here on the 'hide about the Accuracy International boxes and some others...I think I've read of others loading to 2.89 or longer...
Here's a tidbit--my son bought a new Rem 700 in .308 with the 26-inch barrel. Lapua 155-gr bullets would NOT even touch the lands until the bullet was only 1/16-inch or less into the case mouth!
I still haven't used that barrel for a tent stake yet. It was a good, solid 2 MOA performer all day long, if you do your part. Sometimes as tight at 1.3 MOA. Hundreds of rounds of load development.
