Mossberg ATR problem!!!!!!!!!!!!!!
I bought this rifle last year.It shot well and now shoots groups like a shot gun! I've changed bullets and then powder,next was to be the brand of brass.The problem still was there?
I checked my stock bolts and the front one was loose,so i snugged it up? Grouping got worse!
I took the gun apart and looked and thought and looked and thought"What the h*** could be wrong?"
It is a wood stocked and flat black finished barreled action.Then,there it was,a shinny spot that should not be there????
The front bolt was going up into the action to far and jamming on the threads of the barrel[in the receiver]!The shinny spot was crushed threads,on the barrel? The wood stock either shrunk or collasped and now the bolt is too long! This let the barrel and action jump around.
I shot a lot of rounds,these last couple of weeks trying to find the right one for the gun!Who'd a thought it could be that bolt???? Well,me,i should have? I had gun act the same way before but it was pillar bedded[a Savage rifle]. The front pillar came unglued,just enough to do the same thing! Now to fix it?I may either grind the bolt shorter or try to find a spacer for under the bolt head. The spacer is my first choice.
If anyone is interested,i will repost how it turns out?
