Home Forums Hunting & Shooting Ask The Gunwriters New barrel vs a broken in barrel and changes in velocity

Applied DBC before firing the rifle. Fired 10 rounds to cure (naked 105 AM). Average velocity 3012 fps. Cleaned the bore. Fired 5 more rounds (moly coated 105 AM). Average velocity 3007 fps. I have another 5 rounds loaded with moly coated 105 AM that I’ll chrono after 100-200 rounds down the bore.

All velocity measurements taken with LR.
