winchester 525 bulk - metallic shavings

[ncSmitty]

A few days ago, I finished off the last couple hundred rounds of a brick of federal 22lr. I did not have a single failure in the last two brinks of federal.

I then pulled out the white box winchester 525. While putting about 150 rounds down range, I had about 10 failures. Most of them were the casing not ejecting from the barrel. I did not like the failures, but did not give them too much thought at the time.

Once I returned home to clean the rifle was different. When I pulled the bolt assembly out to clean, it made a "gritty" sound while sliding it out. At first, thought noticed what looked like sand covering the bolt, and it appeared that there was sand in the receiver. After I inspected further, I determined that it was not sand, but rather metallic shavings. I am assuming it is from the winchester ammo only because I only had failures while shooting it. Also, I've never had the metallic shavings after firing the Federal's.

Has anyone else experienced this with winchester bulk? I have another 1800 rounds of this **** that I'm not sure I want to put through m 15-22. I'm worried the metallic shavings will damage the components of the action when cycling.

I have a 317 that will probably be fine with the winchesters, but it's not nearly as fun to shoot.

What you are seeing is more likely powder residue from dirty powder, rather than any metal partials. Burned powder residue often looks like sand and makes the bolt feel gritty.

The best, and easiest, thing to do is simply blow out the lower receiver and the FCG with compressed air. Anything over about 60 psi is good.

Wipe all lube off the bolt and clean the inside of the upper receiver to remove any residue from it. The only part in the BCG that needs lube are the bolt carrier rails and then only a drop of CLP or something similar on each rail. Same deal with the FCG, no lube needed on anything other than a minimal amount of lube on the hammer and trigger hooks.

Thanks for the info Majorlk, that makes me more comfortable with this ammo.

I haven't shot any Winchester in a few months, but what you describe is pretty typical with "dirty" ammo.

I just finished off a box of the Winchester 525. I didn't have any problems with FTE but I did get some FTF. Each time it looked like it got hooked on the hollow piont. I also noticed that the gun seemed to require more cleaning.
