[QUOTE="LouBoyd, post: 557420, member: 9253"] How much does the bolt move with the firing pin cocked? Play should be very small. How much with the firing pin released? It should be around a hundredth of an inch. It's not critical but it's supposed to be loose to make extraction easier. Try it in a safe place with a new loaded cartridge. There should be zero free play but don't force it. I'd get concerned if there's noticeable play with a cartridge ready to fire. It's not likely. If you're concerned find a smith with a set of go no-go gauges for your chambering and check the headspace. [IMG]http://t3.gstatic.com/images?q=tbn:ANd9GcSlGNXo0GtQF2q4WXZVF2gt_jCfLpqxeWPdmGx2R7tYujJMgLlg[/IMG] The bolt should close on the GO gauge, It should not close on the NO-GO Gauge. Gauges are typically $50 per set if you can't find someone with gauges. They're normally used when fitting a barrel to a particular receiver so factory ammo should fit properly. [/QUOTE]
