A friend believed his rifle had lost its edge. This was a 264 WM.
Asked about his cleaning procedure and he admitted he had never cleaned it. When I got the rifle it came with 6-800 rounds of 1F brass.
Using six different cleaners from Sweets, WipeOut, JB compound, Hoppe's, and a couple of Remington products.
A final WipeOut treatment produced no blue.
Had the barrel scoped and it would probably see another 200 rounds.
A recommended load was producing 2" groups at 200 metres.
He shot the rifle but we did not have time to test it with WipeOut but he was given a cleaning regimen . . .
