I know you were anxious to get your gun back and even better that it was a complete replacement with all the goodies, but a cracked bolt seems worthy of notifying warranty repair.

I want to complete my evaluation of the gun so I can decide if there are other issues that need to be addressed before contacting Ruger about the cracked bolt.

That's a good idea.

Here is a picture of the cracked bolt. I sent a message to Ruger customer service to see what they want to do. I am hoping that they will send me a new bolt.

I told them about the failures that I have been experiencing and that they seem to be decreasing, as the gun breaks in. I am going to continue to do testing, but I am thinking I will probably end up accepting the gun, since the failure rate is improving and is manageable.

You sure that's a crack? Doesn't look like it goes all the way to the edge. Almost just looks like an imperfection from the pic. That shouldn't effect anything really.

I can feel the crack with my fingernail.

I did some more testing today. I shot 12 full mags, rotated among 6 BX-25 magazines. I retested magazines that had failures with different ammo. The failures did not correlate with specific magazines.

CCI AR Tactical - 1 mag with no failures
CCI Subsonic - 2 mags with no failures
Blazer - 2 mags with no failures
Federal 36gr copper plated hollow point - 2 mags with no failures
Brownell's 36gr copper plated hollow point - 3 mags with no failures
Brownell's 36gr copper plated hollow point - 1 mag with 2 failures to feed at rounds 5 and 9 and one failure to fire with a strong strike
Brownell's 36gr copper plated hollow point - 1 mag with 2 failures to feed at rounds 1 and 9.

I think things are looking up. I didn't have any failures with the CCI, Blazer and Federal ammo.
I had a total of 5 failures out of 300 rounds. All failures with the Brownell's. I think it is cheap ammo. It was $53 for a bulk pack of 1000 rounds.

I am waiting to hear back from Ruger about the crack in the bolt.

I got an email from Ruger today. They are sending a replacement bolt. No questions asked! Great customer service!

5 failures out of 300 rounds is a pretty good ratio with .22LR, especially using the BX-25 mags. You will find the rate tends to increase the farther you get into a shooting session.

I did some more testing today. Before my last session, I reinstalled my extended mag release, extended bolt handle and auto-bolt release.

Today, I shot 200 rounds of various types of ammo, using 6 BX-25 magazines, and only had one failure to feed.

Remington GB - 3 mags with 0 failures (surprised!)
Browning - 1 failure to feed with the first round
Browning - 2 mags with 0 failures
CCI SS - 1 mag with 0 failures.

I need to do some more testing with CCI Minimags and AR Tactical, once I am able to get some.

I think I am there! I can live with this failure rate, as long as it holds.

Here is a picture of the jam. The bullet nose was deformed by the impact with the edge of the chamber. The cartridge has not been pushed far enough forward in the magazine to be pushed up and have the rim slide under the extractor, allowing the cartridge to align with the chamber. Does this give anyone any insight into the cause of this jam?

I did more testing today. I shot 8 mags using CCI minimags, CCI AR Tactical, Brownell's and Remington Thunderbolts.

I only had failures with one of the magazines. It appears that there is a problem with the spring in that magazine. The second and third rounds would not feed. The bolt would not move forward to chamber the rounds. The rounds were not pushed to the top of the magazine, so the rounds were sitting horizontally in the magazine instead of being angled up towards the chamber. When the bolt tried to move forward, the nose of the round just hit the inside of the magazine and stopped the bolt. I couldn't even manually push the bolt forward. I pushed the round down and allowed it to spring up into position. I was able to chamber that round and then it jammed on the next round again. I pushed it down and then I was able to shoot the rest of the magazine. I tested the magazine with two other types of ammo and then with the same ammo that failed. I had no more failures.

I disassembled and cleaned the magazine when I got home. The spring appears to be slightly bent and it is not putting sufficient pressure on the follower. I am going to have to retire this magazine. I wrote to Ruger to see if they sell the spring separately. Fingers crossed...

Ruger is sending me a new magazine - free of charge! Great company!

I shot six BX-25 magazines of Thunderbolts today, with only one failure to feed. I am fine with that failure rate, especially with cheap ammo.

I think my experience with this new replacement gun really shows the importance of giving a gun some time for break-in. I had multiple failures in the beginning and they gradually decreased as I put more rounds through it. I think it really began to improve after 300+ rounds.

I found this mis alignment that I believe causes my ejection problems the slot for the ejector and the alignment key for the barrel are way off
