Bore fouling question..
 

Here is an interesting one for you all....I have a Weatherby Vanguard in .308..24" tube. After a through cleaning, it takes 6 shots or so for it to shoot where it is sighted in at. The balance of my rifles shoot where they are supposed to after 1 fouling shot, EXCEPT this one. Any ideas..?? Its is fairly new, less than 200 rounds thru it.

All input is appreciated.

Ken, can you describe what the rifle does for those first 6 shots before it goes to the zero?

the gun shoots high for the first 2 or 3 and groups poorly.after a few groups (3 shot) it goes back to here it should and the groups improve. They stay that way throughout the shooting session.

Are you fouling with copper or just dirt. If it`s copper fouling that much you probibly have a very rough bore and lapping the bore should help, or you can just keep shooting it and it will work itself out. I did have a .250 barrel that would not shoot out and I fire lapped after abt. 500 rounds befor I could get it to shoot at all. But if yours will group after 6 shots it shoult shoot itself out. I also might help to use Flit or JB Bore Paste when cleaning to speed the rifle in settleing down.
