Barrel breakin with new powders

[kmon]

I know the subject of barrel breakin has been beaten to death, but here is another one.

Newer generation powders that reduce of eliminate copper fouling from collecting in the barrels have some advantages especially in barrels that like to run clean. I am using CFE223 with good results in a 17 Remington that really does like to run clean.

I know some barrels seem to shoot better with some fouling but the old regime of shoot one clean, repeat does get old, very quickly. Why not use CFE or one of the new IMR powders that do not allow for copper buildup when breaking in. No copper to clean so breaking should be faster as far as smoothing rough spots, feathering toward the muzzle...

Just looking for your thoughts.

Something to consider, is the quality of the barrel you are talking about. In other words, is that barrel a hunting barrel on an across the counter hunting rifle or a quality Match Grade barrel? I have for years used the 40 round (shoot one clean x 5, shot five clean x 5, etc) on hunting barrels. But Match Grade barrels are hand lapped and ready for shooting without the BORING Break In. Works for me and something to consider.

Almost all custom barrels are hand lapped at the end of production and as smooth as they will get when you receive them. Most of the copper you see in barrel breakin is from the lead (freebore to rifling transition) getting smoothed out and the copper scraped off the jacket being deposited in the bore.

Fixed that one word. Someone would invariably think "but I ain't shooting lead bullets" or some such......

Call it an "old country hickory dope" helping another.
