    Greetings,

    Since this is my first post on this forum I guess this is also an introduction as well.

    I notice when chambering a round they don't always strip from the magazine smoothly and seem to get hung up before chambering. Looking at the feed ramp I notice a build up of brass on the sides of the ramp and so I am wondering if polishing the ramp would solve my problem?

    These are all reloads I'm firing and I am seating the bullets to AOL spec.

    Thanks for the help.

    Hello Spacejunk and welcome to MVPF.

    Nice score :) The .308 is still hard to find.
    I don't know about .308 MVPs but the 5.56s smooth up as they break in, usually pretty quick.
    Quick questions for you; you working the bolt vigorously and you got any snap caps for dry fire ?

    Oh BTW,,we like pictures :D too.

    Thanks for the welcome. So far I have put 180 rounds through the rifle and the bolt loosened up after the first 50 rounds.

    I slathered my 5.56mm MVP Patrol bolt with a slurry of JB Bore Paste and CLP and cycled the action several hundred times renewing the slurry as necessary. The action smoothed out very nicely. Messy and a good detailed cleaning was required afterwards, of course! :) I did this several years ago with a Springfield Armory (Inc.) basic M1911 with excellent results as well. No reason to think the 7.62mm NATO MVP will be different.

    Thanks but I don't understand how this helped smooth out your feed ramp?

    If the action is sticky or the bolt "stutters" when being closed it may not be the feed ramp at all. I don't have the 7.62mm NATO model but once I got the action smoothed out on my 5.56mm version there were no feed issues.

    Often the 2 feed pawls(or feed horns as some like to call them) get hung up on the shoulder of the top cartridge in the magazine below. This happens whilst retracting the bolt. The easy fix is to never fill the magazine to capacity, 1 less should be fine. This allows some downward travel in the magazine and over all less spring tension allowing a smoother bolt travel both fwd and back!

    It is also advantageous to smooth the rear (ramp side) surface with a file. Just ensure u do not file the contact (front) surface down as it may fail to pick up a round from the mag.
