NEW Pietta PPS50 SBR 12" Barrel 22LR NON-Restricted

[coolspot]

I have one and the 50 round drum and stick mag. I used remington 36gr high velocity 22lr ammo. The bucket of bullets 1400 rounds.
It very rarely jammed or had any issues. This rifle seems to really high velocity bullets and didn't like 40gr cci.

​

I picked up some Remington Golden Bullet, 36 gr at 1,280 FPS, and ran more than 120 rounds without any issues. It’s the only ammo that has worked reliably so far—and luckily, it’s inexpensive.

I've heard that Golden Bullets have improved in quality over the years, and they're not hot garbage like they used to be.

That's interesting, I'll have to try some of those out.

I did initially read in the Pietta owners manual, that it is recommended to run ammo with velocities 1,300+ FPS for proper functioning. All the ammo I've run through this so far, is 1,235 fps (with malfunctions). I'm really curious if hotter ammo will produce better reliability.

Have you had a chance to clean your PPS-50 yet?

I’ve just done my second cleaning and found heavy lead and carbon ring about six inches from the chamber.

The fouling was so built up that my .22 cleaning rod couldn’t pass through, even with a lot of force! The fouling might be from all the ammo testing, but it’s definitely something to watch for, this rifle can burn through a lot of rounds in a session, and it really needs a thorough cleaning afterward.

I ended up drenching the innards of the barrel in Lucas CLP and Hoppe’s No. 9, scrubbing it with a smaller-caliber copper brush, and letting the bore cleaner sit overnight before I could finally push a cleaning rod through.

Here are some photos of my barrel even after cleaning with swaps and Hoppes No. 9 - the clean looking photo is at the muzzle end, the dirty pictures are about 6 inches from the chamber.

I just ordered a .20 cal brush and .17 cal cleaning rod to hopefully better scrub out the barrel.

I had one of those years ago that used to lead up pretty bad, I switched to using just plated .22 and didn't have issues after that.

Man, that looks pretty dirty!

Are GBs dirtier than other ammo?

I've cleaned mine after the initial range day of ~700 rounds, but I only used a bore snake with some Hoppe's bore cleaner (I forget the name of the solvent) to clean the barrel. I didn't inspect the barrel much, but the snake removed quite a bit of fouling. I'll have to do a thorough cleaning after the next time I take it shooting and inspect the barrel closer.

I'm hoping to get out again next week to run some more Mini-Mags, Blazer, and other ammo through this beast. I'll report back.

Are these still jamomatics?

It depends heavily upon the ammo and which mag (stick or drum) you are using.
