Normal Looking spent cartridge?

[AikiNut]

I spoke to a couple folk today. SFRC.com where it was bought...they said I could run a brick of CCI Mini Mags through it as a test. I also called the Ruger Canadian service center in Montreal and they said to send it to them. Kind of a drag seeing I've only had the thing for just over a week. Here is a photo of the end of my firing pin:

Can you take a photo of the whole firing pin with an accurate scale next to it? As well, measure end to end, height, and thickness with a caliper or micrometer and send it to me? I may be able to wire-cut one with a modified firing pin tip that will engage more of the rim... Could be a fun project.

Contact Ruger again, and see if they will send you a replacement firing pin; send them the above photo. If that is a no-go, then send them the rifle. Be prepared for a wait; a friend of mine bought a brand new Mk IV pistol (the ones with the safety recall) and sent it to the service center in Montreal, and got his back just under 6 months later. Try the firing pin exchange first.

That should be the quickest solution. personally the CCI ammo route won't solve a thing..after that if it does not work send it back to Ruger but keep a paper trail..

It'll eliminate the ammo as the issue though. Wouldn't hurt to try.

And Ruger should honour this or any other fixes necessary as the OP would not have done anything without Rugers approval..

I got an email from Ruger in NC today. I had sent pictures of the casing strikes from the misfires and the firing pin. Their reply:
"After viewing the photos that you sent, the technician states that there is a wide selection of things that could cause this issue.
But he would start with the slide.
Snapshot, our Canadian warranty repair center, would be able to perform the repair.
Without having the firearm in hand, it is hard to diagnose the actual problem."

Not sure what they mean by the slide.
I am hoping to get out this weekend and fire a bunch and take some more data.

Dunno, but doesn't the firing pin in actual fact............slide?

Perhaps the tech was referring to the bolt thingie.

She, (the Ruger lady clarified) she was referring to the firing pin.
Well we had a very successful day of shooting. Too bad it was two weeks between outings as I might have been fussing too much. I honestly think it was as someone already suggested..clean the new gun well. A friend took us to a range (we are on their wait list to join also) this morning and we fired off 150-Browning bulk, 65-CCI Mini Mag, 10-Federal Target Grade Bulk, 11-Blazer, 50-Winchester Wildcat, 10-Federal Champion, 20-American Eagle. We only had three failures from the Browning ammo, and when rotated and tried again it fired off. My son had a few jams from the Browning also.
I am optimistic that when the blot was cleaned and very lightly oiled, it has changed the performance. It is hard to believe it would be that finicky.

Now I will research buffing or polishing the micro-roughness of the non-machined (stamped out) firing pin.
Next time out we should be able to focus more on good shooting technique and studying which ammo give us the most accurate groupings.
I was trying the new Warne Quick disconnect scope rings. They are a bit temperamental and came loose once. I had to fiddle between adjusting the screws with the torx wrench and the qd levers.

If you want to polish that piece of crap (what it looks to me like), get some 600 and maybe 1200 wet dry sand paper , lay it on a smooth surface and have at it, all you have to is smooth out the high spots, don't have to have the whole thing smooth, and that end of the firing pin looks strange to me.

 

[McHoss]

Like Marshall says, get some super fine wet dry paper and a flat surface. A piece of glass from a picture frame works well. Smooth the part along its direction of travel. You can use some light oil towards the end to get a very nice finish. Just remember that you can always take a bit more off but you can’t put it back on, so slow is the word of the day.
Glad to hear you had better luck on this outing.

Polish the side of the slides as mentioned and take the nose off the hump in the middle.
Force the firing pin to whack the edge of the ammo.
Need to pull mine apart and see wtf the firing pin face looks like.

I polish rough surfaces with 3-M Scotchbrite Rolloc pads in a die grinder. I first started using these when spotting in dies and punches in die sets. They work amazingly well:

I have used these and they do work well for certain applications. Wouldn’t they be a little hard to manage in this application though?

I use these at work all the time and they will remove more metal than needed when used in a die grinder If you're not super careful. I would use the super fine sand paper and a straight surface as suggested by others.

That’s what I was thinking as well.

Use the super fine ones, and turn down the air flow to the grinder. I only ever use them to polish.

Well I've have had good outings and less good ones since polishing my bolt. One thing I know is when there is gun oil on the firing pin, it misfires more. A guy at the range had me try some synthetic spray lube. Then I had 2 in 5 miss fires. Took the bolt apart and wiped it dry again and it functioned better.

Try Remington Dri-lube?
