H&R model 157 22h ser no. AP... pre transfer bar model in need of repair

[normbro]

Hello,
I am new to posting and I am asking for some guidance here. I have acquired a H&R model 157 22 Hornet 1976 pre transfer bar model, serial no. AP... the previous owner attempted trigger work, making the rifle inoperable. The firing pin is broke, the hammer will not cock. It is a neat looking rifle with full length Schnabel type forend with a black plastic trim cap, folding rear leaf, and a drift adjustable front sight. It has sling swivels, which the front swivel also doubles to connect the forearm to the barrel.
I have seen reference to Brian56? in the stickies.
If the rifle's parts are still available, I would like to get it fixed, if possible.
Thanks for your help

Hello and Welcome to GBO H&R section- you are among friends here.  Brian56 is going to have the most answers for you although he may not have all the parts. ONCE he told me he did not have a part I was looking for but every other time he has been able to help me.  If you send him a PM with the info you shared above he will be able to advise you way better than I can. But many here fix these all the time, I am just chicken and try to send it to Brian56.  Good luck and let us know how it shoots when you are all squared away. thejanitor

If you have basic mechanical skills, read the FAQs and work clean & careful you can do it. Gun Parts Corp will probably be your friend and the older, pre t-bar 'works' fit the rifle too. There have been several sizes of firing pins and Brian may be able to advise better a specific one; or get a shotgun one from that vintage (big dia.) and thin it to fit. While apart you should probably put in a new dbl. leg hammer spring, see Wolff springs to get a good one (those from Gun Parts are unknown for age/use).
Big questions are, why is the f-pin broken and whats really going on in the not cocking issue. You have to cure the cause not just replace parts.
"the front swivel dbl's to connect the forearm".......really? I didnt know that. Is that along with the forearm screw too and up into its own extra stud on the barrel?

Thanks for the info guys. I think I'll start by contacting Brian, getting some new springs,and work from there.
 
gcrank1- The previous owner explained the firing pin broke while dry firing. The Sear and hammer notches were "stoned", but only lasted a short while before the hammer would not engage anymore.
 
The sling swivel is also the forend screw, it is one unit. It is long enough to go through the forend and thread into the barrel stud. There is no extra stud.

Ahhh, good you know all that! Fitting a new pin is easy, clean the channel good when in there, crud accumulates over time.
You wont know what you need until you get the hammer & trigger out, maybe a broken tip on the trigger sear tip? Use a punch to drive out the pins (they are splined on one side, drive from the other), put a fired empty 22 case over a steel punch tip to keep from marring the pin or (shudder) the frame if you skid off. You will have it apart in minutes.
I kind of expected that is where your sling swivel is; it is solid but the gun wont hang on a shoulder worth a hoot with it that 'low' on the front (it'll hang but shift horizontally pretty quick) unless you hang it 'butt up'. That works OK until you kneel down and the muzzle goes into the dirt.......(dont ask ).

I got the Model 157 22h  back last Thursday, and Brian56 had all the parts necessary to make it shoot again, and he did some additional needed work that I did not even think about. Brian56 went above and beyond. Thanks everybody.
 
I tried some factory ppu 45 gr sp loads, and they shot pretty good. I think I can improve on that with some handloading.
