12 USH Problem (not firing)
« on: January 16, 2010, 04:29:54 PM »
Just bought a 12 ga USH (used) went out to shoot it today and it would not fire ,I"m getting small indentions on the primers but not enough to fire,It locks up tight ,I'm pulling the trigger all the way .I oiled it up the other day could that be a problem . Just trying to figure it out myself before I take somewhere to have it worked on.Thanks John

Take the barrel off, then cock it and pull the trigger, hold the trigger back after you pull it and see how far the firing pin sticks out.  I am thinking it should be about .050 to .060 or so.  If it is out far enough then it is probably just a weak firing pin spring.  Larry

Welcome John! I think Larry meant a weak hammer spring, it's not uncommon.

Brownells and Midway both carry new hammer springs, Midway carries Wolff.

Do you possibly think it might need to be cleaned or is this a pretty common problem . Ive had two other H&R's this is the first time I've ever had any problems. Thanks for all the help . John

It's not a new problem with the USH, there are several threads on past pages on this problem, if a change in ammo doesn't solve the problem, I'd contact H&R and have it fixed on their dime.

Went out and shot it again today with winchester slugs instead of remingtons and it worked like it is suppose to . Shot 3 winchesters and then tryed one of the remingtons same thing for some reason it doesn't like to fire with the remingtons,I wonder if that's a common problem or am I just lucky like that, now I've got 3 boxes of remingtons i can't shoot . O well at least it's not the gun itself. Thanks for all the help and suggestions.Thanks John

If pin projection is less than Larry's specs, you can always remove a little from the face of the hammer where it stops against the frame to see if you can get the Rems to work.  ;)
