Lapping a new barrell??

[Catfish]

I have fire lapped several barrels with mixed results. I only fire lap them if I`m convinced they have a problem. Lapping of fire lapping a barrel has about the impact on a barrel as fireing 500 to 1,000 rounds through it, your wearing out your barrel. I had 1 Douglas barrel that was suposed to be air gaged that was rougher than a cob and would not group at all untill fire lapped. I think the guy that built my gun lied to me abt. the barrel. I fire lapped a barrel that became fouled with Molly and got it to shooting again. Other than those 2 I have never gained much in accuracy, but they are eaiser to clean. Personally I recomand lapping or fire lapping as a last resort.
