I,m in the process of accurizing-bedding,new recoil lug,and possible switch barrelling a Savage 300wsm pre-accutrigger model when I noticed after I got the barrel off there was some noticeable spots(6) about 1/16 in diameter from the throat to about 2 inches forward. I could see them by using a magnifying glass and a borelight. Now I've only run approx. 60 Winchester Nosler's coated with lubolux down the barrel plus 20 Federal fusion. I broke the barrel in with 20 Winchester bullets using the recomended cleaning-shooting procedure.I always cleaned my barrel thoroughly with hoppes 9 and shooter choice 7. Even brushed it. I would repeat till patches came out clean, then oiled.
Has anybody have any experience with Winchester ammo coated with Lubolux and possible bore build-up, or pitting as a result of the coating?
I'd appreciate any input Thank You.

Welcome to the forum Brian. Rules are simple, be nice and join in.

I've never heard of lubolux hurting a barrel. I'd suggest you contact Savage and tell them about the problem. Their very good about fixing their rifles.

Thanks I think I'll contact savage and see what they say. To tell you the truth I dont trust any coated bullets now unless the barrel was properly conditioned for it whether molly or others.

How does it shoot, if it shoots well I wouldn't worry about it. I have a few factory rifles with noticeable with the naked eye blemishes that still shoot fine. I don't see lubalox coated bullets causing the problem, could it be from the cleaning rod contacting the bore?

It shot OK I guess 3 shot 100yrd group 1inch. I would have never been able to see the spots if I wouldn't have the barrel off. I eventually plan on getting new barrel (26") in 260 and new bolt or bolt head. I still want to use the 300wsm. I guess I'll wait untill I get the bedding done etc and shoot it before I decide what to do. When I took the action off the stock it was pillar bedded but the action was still resting on all the wood. Thats what prompted me to begin this project in the first place.
Again thanks for all the input guys i appreciate it.

I've used lubalox bullets with no known problem in the past

I once had a Mauser 98 rebarreled with an E.R. Shaw tube in .30-06. The bore had obvious chatter marks down half its length, and tended to gather more than it's share of copper fouling, but it was one of the most accurate I've ever owned, grouping several loads into .5 - .75" at 100 yards. Early on, I knew I'd put up with the hassle of frequent cleaning rather than get it replaced, even though Shaw offered to do the swap for free.

I have a 7mm Sako Forester and the riflings appear to be coated with a bronze color. I thought at first it was rust or copper fouling but that does not seem to be the case. I was wondering if this is a problem or the riflings come lack that from the factory. Since new the rifle would group 2 shots and the third one would be 4 inches off. I have tried different scopes a new free floating stock and various bullets and powder. I thank you for any suggestions

Don't forget folks that a bullet does not achive it's "final shape" until it leaves the muzzle. Defects that occur near the throat can be "ironed out" at the muzzle in some rifles. A "bad" muzzle will wreck a group more often than a "bad" throat.

I think of a barrel as a "long bullet sizer die". Better to have it smaller near the end than the begining.

My Savage model 12 has some reamer? marks in the bore. Had a tendency to hang onto jacket material when I was breaking in the barrel but didn't seem to affect the way it shot. Now, although the marks are still visiable, there is no problem with fouling and the rifle is truely accurate.
