+1 =A lot of good advice by all.
Also remove one bedding screw at a time and look in the hole to see if the action threads are centered in the pillar and the screw it not touching the pillars. If they are, drill them out just a
little where they are only touching the action and the floor metal (If they touch they will become
recoil lugs and realy screw up the groups.
Next clean the barrel back to bare metal with a strong solvent and do a mini. break in (5 rounds
of shoot and clean) if it still fouls it is the bullets or the barrel. some barrels just foul worse than
others and must be replaced.
Hopefully it is one of the other things mentioned and you won't have to replace the barrel but
every now and then you get a bad barrel.
