Ruger PC Carbine Accuracy

[Reeferman]

I finally got out today and shot 490 rounds through my ppc. First 200 were American Eagle 124 grain and had 3 stove pipes after first 100 rounds and the rest were fine. Shot 200 American Eagle 115 grain and first 3 jammed failure to eject. I was a bit disappointed, however I realized that the Caldwell brass catcher I have strapped on moved down and top of it was blocking the cases from ejecting. I’m pretty sure that it wasn’t the issue with the 124 grain that had stove pipes but can’t be 100% sure.
Adjusted and went through the rest of the 200 rounds no issues. Also shot another 40 reloads with a 115 XTP over 4.9 grains of 231 and not an issue plus another 50 124 commercial reloads and again no issues.
Appears that the filing and polishing to the rear of the bolt face made a huge difference. It still is the dirtiest gun I’ve ever owned. Cases are black worse than any blackpowder gun I have.
My SR22 1022 had about 800 rounds through it today and it looked new compared to this PPC.
I can’t complain about how accurate it is. With the factory peep at about 40 yards I was really happy with it for my 65 year old eyes and the was really windy.

If you were using a brass catcher for all shots, then yes that was your issue.

It was doing it before I had a brass catcher. First time out after 40 or so rounds it was locking up and jamming every 2 or 3 shots. I then installed the Mcarbo extractor, springs, buffer and pins and made a slight difference.
Like I said I can’t say for sure that the brass catcher caused the first issue in above post but can’t say for sure that it didn’t.
It doesn’t matter as the modification to bolt head seems to solved my it other than how dirty it runs.
I really recommend if anyone is having issues like I was to consider filing and polishing the bolt head as it is a different gun now.

Twoforscrews sorry for hi jacking your thread I’ll start a new one if other issues come up with it.

No worries. I'm glad ya did

The PC carbine weighs just under 7 lbs unloaded. All up with an optic and sling and we’re pushing 8 lbs. If I’m packing rifle weight, I want a rifle cartridge.

The Beretta is a much lighter, handier carbine. It is also shorter due to having the magazine in the grip.

The Beretta has more muzzle jump and felt recoil than the Ruger PC9. I was interested in the Beretta until I rented and shot one.

I have a Ruger PC Charger pistol in 9mm, very good accuracy out to 25 yards for a short barrel pistol. Doesn't seem to dislike any 115, 124 or 147 gr. loads.
For my 16" 9mm carbines in general, 124 gr. NATO loads seem to perform best. Although I mostly run el cheapo 115 gr.
Most of my 147 gr. factory loads are truncated bullets and while they do fine out of short barrels at short range don't group tightly out of 16" barrels at 100 yards, which IMHO is a 9mm's 'effective' range.

That was a concern when I looked at them. Then I wondered which is better, a large aperture that far forward but on the same piece as the front sight or a smaller aperture further back but on a separate section on a takedown rifle.

That puzzled me as well. Having the aperture out on the barrel somewhat defeats the purpose.
With a properly placed aperture, your eye centers itself on the brightest opening, and turns your eye itself into the rear sight; then just put the front where the shot is to go. This is why a cheek weld is important with an aperture.
Too, a sight back on the receiver, or tang, really extends the sight radius.
The older, one piece Ruger has the aperture where God intended, solidly bolted to the receiver, guarded by stout ears.
Two questions:
-For yinz using optics, where do you mount them? On the receiver or the barrel? The Picatinny rail appears to be on the receiver; if it is okay to mount the optic there, why not the aperture sight?
-Where is the mass of the bolt on the current carbine? On mine, the weight is slung under the barrel, forward of the receiver.
Thnx,

I could be way off here but I think why they did it was to have the sights locked always in the same position relative to each other,because of the take-down feature has minute movement from disassembly/assembly. I agree the aperture sight is wasted where it is,except for fast target acquisition. I have a Winchester 94/22 with a semi buckhorn sight. I changed the blade for one with a aperture. It didn't take long for me change back to the original one as it was more or less useless that far from my eye. I put a ring and dot reticle RDS on my PCC and it is kind of hard not to hit POA.

 

[halfmoonclip]

JohnB, you are no doubt correct as regards why the rear sight is on the barrel, due to the takedown.
But I still don't get why the optic can be correctly mounted on the receiver, but not the rear sight...what were they thinking?

The front and rear sight bridge the gap over the connection while an optic doesn't?
