Strange as it is, this guy shooting a P22 with Remington .22LR was tossing shells at me this morning. I looked at one and it had a swollen ring just forward of the rim. Examining others, I see they are all swollen just forward of the rim. It looked like the shell wasn't ramming all the way forward or the opening had a large chamfer on it. I called his attention to it and he said he has been having trouble with shells blowing the rim off.

He shot a clipful of my Federal 550 and the problem went away. I shot some of his Remington's in my Ruger MkIII and all was well.

He went back to the Remington's and his shell swollen rings returned.


If you are using the Remmingtons, watch for it.

I came to that conclusion long ago. I don't shoot Remington ammo in any gun that I care about. Likely the cartridge brass wasn't gas sealing properly. That meant they were coming out of the chamber slightly prior to sealing against the chamber wall. This would account for the bulges. Obviously the rounds were seating fully or the rims would not have detonated, the firing pin has to crush them against the chamber rim to get a detonation. The brass is partially ejecting under blow back gas pressure causing the bulges in the spent cases. The same applies to the cases where the rims were blown off. The cases just ruptured due to pressure and lack of support. Another brand of ammo is the solution to that problem.

I too will admit to useing some of the Golden Remington Bulk ammo in the past..
I had losts of FTF FTE etc with 10/22s & MKIIs with the Remington but this ammo ran 100% in My Remington Nylon 66 made in 1959 BTW..
When I switched to the Federal 550 Bulk Ammo almost all my troubles were gone, In fact with a Volquartzen extractor in both guns they were 100% except for a dud round now and then..
The Remington is coated with a wax & this also seems to cause alot of the problems & packs in the chamber after alot of shooting..

I too would advise your Buddy to change to the Federal 550 Bulk & Never look back..

+1 on Headknocker's comment I've had nothing but bad Ju-Ju with RGB's

Over on RFC the P22 fans seem to think RGB is the ammo of choice.

I've tried a brick of Thunderbolts and three boxes of RGB's. The T'bolts weren't all that bad, just incredibly dirty. The first box of RGB's had a 30% failure to fire rate. The second box wasn't good, but not that bad. The third box had inconsistent loads or assembly. You could hear them going bang or pop. AND the P22 didn't like them. Gave up on them and would only buy them if there was nothing else available.

The first box I put through my MkIII was RGB's. 2 duds out of 100. I'll be switching too.

When I bought a Bretta Neos in December, I bought a 525 box of Remington Golden and a 500 box of Winchester Xpert 22.

The Winchester's had a more blunt or square end and the Remingston's had a rounded end. Out of 1,000 rounds the Winchesters had about 10 FT feed and the Remingston's had none. I learned you had to tap the magazines so the cartridges were toward the rear of the magazine and all FT feed's stopped.

Not a single FT fire from either.

That's strange because the ammo threads keep asking why people keep buying this junk. And Threads of casing blowing out and not fully seating into the chambers.

Most people buy them because that's all on the shelves. All of the good ammo is gone and it's the only one left.

I just want to make a small point.

While I have yet to take my Mark lll to the range , My Neos used a spring loaded striker that was released with a sear. The striker was moved rearward by the action of the "slide", and the spring tension moved the striker forward. I did not have a single non fire, in 500 rounds. IF the Remington Golden is not working in a Mark lll, I would look to the Mark lll, not the ammunition.

The Mark lll is fired with a different system. However, this is just my opinion, based on 3 months experience with a Neos.

Some FTF rounds fire on the second try. If you take some apart you will find that the primer material was not all the away around the rim if any at all.

The biggest problem with rem ammo is leading.

My MKIII shoots anything, but I do not feed it Rem.
