I'm interested in that barrel. Mine is a 20" Krieger HBAR. It's great, but it makes the rifle heavy as hell. How much does that thing weigh and what kind of results do you get at 1k?
My 77gr Tmk load goes subsonic right around 930-950 and my best 10 round group at 1000 has been about 2 MOA - but 3 MOA is more typical.
