[QUOTE="shortgrass, post: 1104927, member: 24284"] Those PT&G bolts come with a tag that states "Bolts Require Fitting",,, or some such instruction. I'd not 'work the bolt to the action', I'd go ahead and fit the bolt. This problem originated because the bolt wasn't fit. Similar problems originate with "an old 700 action". How old? 700s wear and stretch over time. Heavy loads and improper or lack of cleaning contribute to the problem. I've seen many where the race way , at the rear, is worn larger than at the front. Hard to 'size' a new bolt properly without reaming the entire race way to a uniform size. Feed problems can arise when the owner wants to "install the stock himself". To cure feed problems or deficiencies the rifle needs to be fully assembled to obtain the proper results. Potential problems aren't recognized until the rifle is completely assembled. Sometimes, the magazine assembly just 'drops-in', and just as many times it doesn't. Standard cartridges usually give fewer problems, I say "usually". I had a .260 Rem. (on a 700 SA) come to me, a few months back. Another 'smith had built it and the owner was very pleased with the accuracy of the rifle.
