RE: remington's 3" accuracy guaranty
You know in manufactures defense, can you imagine the guys that send back guns, that go to the range with whatever is on sale at Dicks sporting, fire off 10 rounds in a row. Guns red hot, and load up and do it again. Expect little cloverleafes at 100 yards.
Or the ones that use Hoppes nitro cleaner and puts 100 rounds thru the bore without removing any copper.
Thats the reason in my companies products we have margin built in. Our product 95% of the time works much better than our specs, but due to test equipment variations, and mostly operator error not properly cleaning thier optics, we have to build in crazy margins.
