Firing pin spring rubbing inside bolt?

[elmerdeer]

Hi guys, I have a model 70 win that has been accurized and I have changed the firing pin spring inside the bolt to a heavier spring 28#, instead of the 24# it comes with originally. I have noticed that the spring seems to be rubbing inside the bolt as put the firing pin back inside the bolt.
My question is can this affect accuracy at all it seems I get fliers regularly?
My gun is win Mod70, featherweight stock Mcmillam, pillar posted and bedded, barrel is a fw Krieger, crown is 11degrees, with a muzzle brake. I shoot of rear bag and atlas bipod, I get 1moa at 200yards on most of my load development with 5 rounds, caliber is 280AI 9.5twist.
Any ideas?
Thanks
Elmer

The spring hitting the inside of the bolt housing sure won't make it shoot any better...

Preachers right"' FYI This year a person who shoots competetive benchrest had a problem with accuracy falling off. It turned out to be a firing pin spring rubbing inside the bolt body. Lock time got slow and it was giving misfires , due to soft hits.
