Barrel Break in for New Grendel

[skyfish]

My own feeling are any high quality hand lapped barrel should be ready to go. I may run one or two shots and check with a swab, but that's it. Production rifles may need a bit more, as they are not(to my knowledge) hand lapped.

If Shilen doesn't recommend, sounds like your ready to go.

I do always clean well before the 1st shot. Any oil, rust inhibitor or particles left after manufacturing. We want a range report!
