My good friend has a FN tactical rifle that is chrome lined. We went down to Frederickburg, VA to meet with people who test them. They claim no throat errosion within 15,000 rounds in 308Win. So I have kept close tabs on the throat length of my friends FN SPR A1 rifle. It hasn' t changed a bit in 500 rounds. Now my 300RUM, is a different story.

I figured someone would do this procedure for a 22-250 or the new 223 WSSM. Also, to boot, he gets no copper fouling at all. No brushes and no scrubbing. That would be outstanding for the Varmit shooters of the world.

Hi bigcountry ,
corrosion resistance is the primary reason for chroming a barrel or receiver . Wear reduction and reduced fouling are an added plus , but probably weren' t figured on when gun makers first started doing it . In those days the chroming process wasn' t as good as it is today , and the chrome tended to flake away after awhile . This doesn' t mean that you can slack up on cleaning .

What I liked about shooting the gun was that fouling was almost nonexistent. Took two cycles of sweets and nothing more came out. Very nice. Also the gun is extreamly accurate.
