That was an interesting article. Looking forward to reading some of the letters.
When I hear the extremes that some people go to when cleaning their barrels, it kind of makes me cringe.
I have tried the Firelapping product on a Bone Stock Springfield M1A, the Standard Model.
It had about 100 rounds thru it and still would only group around 5-6 Inches.
To be fair, I was not shooting Match ammo, It was for Break In.
After the FireLapping and a thorough cleaning with Kroil and some Dry patches, It shot more like 2-3 Inch groups.
Still not using Match ammo.
Next Range trip it will be Gold Medal Match.
For cleaning, I am lazy. I would prefer to just give it a patch with Kroil and then dry Patch it before next use.
