[QUOTE="Don A Parsons, post: 1793496, member: 97414"] I have a custom PTG bolt in my one rifle and a B Galloway worked over bolt in my other,,, my other factory Remington has the factory bolt... So my question is,,, which of the 3 rifles shoot 1/4" or 1" MOA on good,,, and not so good days,,, actually all 3 of them do Galloway spins the firing pin and removes the slop in them by building up to head """and""" making sure that the firing pin is dead straight,,, then working them down,,, he dose the same thing with the Outter bolt shank so it stays true in the action,,, its an old bench rest bolt work over trick... The idea behind a tight / snug fitting bolt is the trigger release is much more constant since the heel of the bolt dosen't have up-ward or side jump when the trigger is pulled... That way we can set the release shear at its lowest point of a safe hold Just enough,,, but not to much... Its something to play with,,, """not recommended for those that don't understand how the system works on different brands of triggers and firing pin releases...""" I'm strictly a Remington and after market trigger dude that follows my leeds advice... He has many years at this stuff... One thing I do like about the PTG custom bolt is the snug fit and the super small pin-hole,,, it works hand and hand for my Palma Brass since I use small primers for it,,, way less flow back of the primer material into the bolt hole...
