Failure to fire
« on: October 29, 2011, 10:13:00 PM »
I know this has been posted before but all I could find was info on newer transfer bar guns.  I have an older, 70s vintage, h&r model 158, 30-30.  Yesterday I had 8 FTFs with ammo I had reloaded.  All had dented primers, Fed210, and its a load I have been loading for years.  Being an older gun with no transfer bar I didn't think trigger pull could be the problem.  Any ideas?

Being an older rifle, the first thing that comes to my mind is perhaps a tired spring.

Replace the hammer spring with a Wolff(FAQs) extra power spring(double coil probably) and R&R the firing pin and spring to clean it good, some dry lube cleaner like One Shot or Slide-All might help without removing it tho.

Thanks for the replies. I thought it was probably the hammer spring but its good to hear it from someone who knows more about these guns than I do.  :)

Also make sure your reloads have the primers seated well. I got a few FTF out of some 7x64 factory loads last week and you can see the ones that did fire seated the primers the rest of the way and fired. Kurt

My old 12ga sat too long, I guess and I had FTFs. I dropped the firing pin and cleaned it all out good, and replaced the strong factory return spring with a lighter one I had in my bins. My F-pin protrusion with hammer down was also a little on the shy side so I gave it a tad more (this requires filing, proceed with caution even if you think you know whats up).
I figured I had nothing to lose, so I jigged up the dbl leg spring and referenced its bend, then tweaked it for more tension.
Ive had no more FTF yet, and will, one day, get a new WOLFF spring (yes I will, I really will).

I agree, get the wolff spring and forget about it!
 
Good luck,

 The only time I've had this problem, it was caused by laziness on my part-simply not cleaning the primer pocket before loading.   What primers are you using?

I'm using federal 210 primers, I always clean the pockets out.  I load ffor several calibers and guns and this is the only one I have had a FTF with.   we got hammered with snow this weekend so I can't get to the range again.  If it melts by next weekend I'll get back out and try again.
