[QUOTE="Litehiker, post: 1711925, member: 54178"] Yesterday I went to my range to sight in my new 6.5 PRC X-Bolt. Managed a 3/4" final group at 200 yards off a bench rest - cement bench, cast iron rest. I shot 18 rounds with no cleaning between rounds. Today I'm soaking the barrel bore in Slip 2000 Copper Cutter solution for 20 minutes then cleaning it with a plastic brush and patches. Since the barrel was already factory lapped I saw no reason to clean between each round. The lapping IS the break-in when compared to un-lapped barrels. (IMHO, that is) The next tim I shoot will be for a Magnetospeed V3 velocity check on my ammo. Ten rounds for a decent average velocity and then I'll clean it with Hoppe's #9. That should give me enough copper residue remaining for good accuracy. 1. Anyone see any problems with this "method"? 2. Would cleaning every 40 to 50 rounds be enough? (With copper cleaning every 200 rounds?) Eric B. [/QUOTE]
