I have a old remington 512 which was my fathers. I dug it out yesterday to sight it in for squirrels this year and figure out what ammo it liked best. Problem... certain brands of ammo would not fire on first strike of firing pin. CCI both CB long, stinger, and mini mag about 25% of the time. Win LR went off about 95% of the time. Win shorts about 80%. Rem blue stripe tagets went off 100% and gave nearly the best group ~ 1" at 50 yds. Aguilla Colbri wouldn't go off the first time at all. If the round didn't go off the first time went off on the second strike of the pin. The Cb's had the best group, and I like being able to hear the gun click then hearing the bullet strike but they need to go off all the time. Any ideas? I cleaned the bolt as best I could, but could not figure out how to disassemble it. The firing pin mark wasn't as wide as my 10-22 but looked as deep. any thoughts??????

  Richbug, The 512series was made from just before WWII up until around 1960 so your dad's rifle has no doubt seen a lot of use. If it has a serial number it was made sometime around 1955 or later. It sounds to me as though you are simply not getting hard enough strikes on some of those cases...the brass must be thicker at the rim than on the others. My money says that the bolt is clogged with fouling and the only way to clean it is to disassemble the bolt. The striker spring or striker spring plunger could very well be so dirty that they can't give a hard enough push to the firing pin and it can't crush the rim.
  
  There is no way that I can tell you in a post how do disassemble and reassemble a 512 bolt. You'll need a vise, correct sized punches and a steady hand as it is easy to shatter the bolt's endpiece...disaster! I always felt a real weakness of these Remingtons was the difficulty of stripping the bolt. My dads old Marlin 80 is damned near as bad...you need a vise. I guess the manufactures figured you'd lose interest in the rifle before it came time to clean it! Seriously, I'd take the bolt to a gunsmith and let him do the job...it will cost you a few bucks, but I bet it solves your problem.

  The bolt is a replacement part which was new about 2 years ago for a 513. Bolt is of unknown origin. The rifle has no serial#. I bought the bolt because my father broke the extractor before Vietnam misplace the bolt and we found the rifle when cleaning out my grandparents house a few years ago.
  
  thanks for the insight

  Richbug, wish you'd mentioned that before, it would have saved a paragraph! Diassembly on the 513 bolt would be the same however. The CMP shows 513 bolts- in fair condition for only $10 each. At that price you could stock up on spares and then just toss them away.
