Default H&R M12 bolt issue?

Hi Fellow small bore shooters,

I'm NOT familiar with bolt proper maintenance on the M12 So I am asking for help with this problem. I don't want to damage the bolt.
For some reason the bolt action on my US M-12 rifle is harder to cock & lifting the bolt after firing then before. I have the rifle about two years & have cleaned it a few times with no problem.

I did not have any problems last time I shot it.
It's in a good quality gun box so dirt should not be a issue. It's still on the money at 100 yards. I did try three brands of QUALITY 22 ammo with the same results.

Please post here or drop me a PM THANKS in advance,

broom

Well the obvious "clean the bolt well".
When cleaning my recent acquisition, I found that the cuts for the extractors on the chamber face really gathered a lot of gunk.
Don't think that would be your issue, but I think cleaning is the first step. Your bolt may have picked up a lot of shavings internally.

Good luck, keep posting your progress.

Have you tried a small amount of grease on the camming surfaces? At the back of the bolt body there is an angled surface that cocks the firing pin as the bolt is rotated. I always put a little grease there as well as any place contact is made as the bolt is worked. It's easy to see those places as they'll show surface wear.

Hi Guys,

I'll try to give it a good cleaning tomorrow.

I hate to try to take it apart, will read up on it BEFORE I try.
I'll flush it out well & drop it into the ultra sound cleaner.
Then oil & grease the recommended areas.

Thanks for the quick reply's!

Hi Doubs43,

I'm STILL trying to get over to your range again & shoot a match or two.
You had a GOOD bunch of people there.

My pal is a shooter & we have talked about it a few times. We did make it to the CMP Vintage Springfield match's in Camp Perry in Aug 2019

Between real life & the virus scare we are being careful about traveling. I'm sure we have saved some money by NOT attending gun shows.

Be well & ENJOY each day,
broom

If you have an Ultrasonic Cleaner, I think that will do a good job getting any grit/hardened grease/bullet lube out of the inside. Taking it apart probably won't be needed at this time.
I don't know if you have a manual, here is a link:
https://www.rimfirecentral.com/forum...d.php?t=379416

I think you will be shooting cloverleafs real soon!
Keep us posted.

Hi JJM,

I had some snippets of H&R info I found on the net! This file appears to have just about everything I will need!

As "WE" know even with good information when "WE" actually get in there.
The writer did not mention to hold assembly R in your left hand while pressing on part X with a wooden rod to remove it without a fight! LOL

I hope other owners will make a copy & keep it with the rifle!

A very sincere BIG THANKS to you for the complete PDF file!

Hi JJM,

The rifle will shoot & has shot- much better then this operator ever will.

Even with the present older shooter behind the sights with both the original Redfield Olympic iron-sights & the recently added classic 10 X Untertl scope. It's scary accurate out to 100 yards. Never tried for 200 yards yet!

I was 19 when I saw my first H-12 set up with a UNTERTL scope... I knew then one day I would own one! It took a LONG time.
But now I HAVE it & ENJOY the heck out of it!

Younger guys have NEVER seen that type of long scope & are astounded with some for the groups I have saved. The poor ones are naturally destroyed in the spot It will be with me for a few more years!

Thanks again,
broom

Hi Fellow shooters,

I just want to thank the very helpful members AGAIN that have replied to my post on the board & also sent very helpful PM's too.
I'm sure I would have damaged the bolt trying to take it apart in the WRONG order.

The H&R bolt is a very different animal then my two Mossburg target rifles!
They are M-44 & M144 LS - great old rifles!
I used them for 18 years with the Boy Scouts. I used them for small game hunting too, because they were all I had

Be safe out there & ENJOY each day,
broom

Broom, we'd surely enjoy having you at our match so please come anytime you can make it. Our schedule is posted on our website: www.fortvalleygc.net You and your friend and anyone else who would like to shoot are welcome.

We shot a match today and it was the IBS target at 50 yards. It was a beautiful day for it with not much wind but still a bit tricky. Seven shooters and I was lucky enough to shoot high score with a 249-14X. Second was a 249-9X and third a 249-8X. I was surprised that there were no 250's shot.
