Remington 740 Question

[wolfz]

I have a question on the Remington 740 I have. It shoots well (accurate at 100 yrds (1.5_2" groups), it ejects all my fodder very well, but every primer, on every cartridge tends to back out(not all the way! At least not yet!). This includes Remington factory "core_Lokted", and handloads (from minimum powder charge up!). Can Anybody tell me what is going on? Is the chamber over_sized (measured brass after firing and it seems fine), too much crimp? (The same cartridges in a bolt action do not have this problem). Or is this something I can expect from this rifle?

I'm going to post this question on a couple of the other boards as well in hopes to finding out what is going on. Thx, Wolfz

Wolfz, is your chamber dry or oiled when you fire. Oil or dirt in the chamber can cause the primer to back out. You might also consider having the headspace checked. I don't really think that's the problem but it could be. Without actual inspection of the rifle it's difficult to say exactly what is causing it. George
