jonb. Posted July 15, 2019 Share Posted July 15, 2019 I have a Shadow 2 that I shot for the first time at a match on Saturday. I experienced a few light strikes with an 11.5lb main spring so mid match I put the factory back in. Even after going back to stock I experienced 2 more light strikes. So I went back to the notes on my original shadow targets in the hopes I will be able to recreate what went right with that pistol. My target runs flawless with any and all primers and it has an extended firing pin and Rami firing pin spring as well as a 13lb mainspring. Since I had both guns apart I figured I would check to see if the extended firing pin from my original shadow would fit in my shadow 2 unfortunately it was snug and I didn't want to force it down. I went ahead and ordered from CZC a 12 and 13lb mainspring as well as the extended firing pin and rami firing pin spring. My question is what if any fitting is involved with a firing pin?

Red_Dot Posted July 15, 2019 Share Posted July 15, 2019 None. What primers? Did you take a close look at the FP nose? Just curious. Link to comment Share on other sites More sharing options...
George16 Posted July 15, 2019 Share Posted July 15, 2019 Not sure about fitting a firing pin. However, did the round fire after the second strike? If so, it’s a high primer if it’s a reloaded round. Im using an 11.5# mainspring with an extended firing pin and reduced firing pin spring without any problems lighting of even CCI which is considered one of the hardest primers around.

Single action Federals are well known for being soft and requiring a deep seat for lighter hammers. Next time try pulling trigger again instead of jacking the round out. If it fires, the primer wasnt seated deep enough. I have a CZ 75 with some trigger work. With the 11.5# main spring, it will require a second hit on a high primer (Fiocci). With the 8#, the primers had better be seated deep. My S2 with an extended FP and 11.5# main spring has been pretty solid, but I have made sure my primers are .005-.008 deep.

With a hammer-fired DA gun, flush primers are high primers. The federal-primed ammo in the background was seated at “flush is good, right?” depths and wouldn’t run in my Tanfoglio. The winchester-primed ammo in the foreground was seated .004”-.006” below flush and ran great despite having harder primers. Link to comment Share on other sites More sharing options...
igolfat8 Posted July 16, 2019 Share Posted July 16, 2019 (edited) MemphisMechanic, How can you seat a primer any deeper than the bottom of the primer pocket allows??? Edited July 16, 2019 by igolfat8 Link to comment Share on other sites More sharing options...

In my Dillon, I set the primer seating punch/cup higher from the primer slide so it can push the primer deeper into the primer pocket. Link to comment Share on other sites More sharing options...
ringram Posted July 17, 2019 Share Posted July 17, 2019 Yep. Apparently -0.006 is about the right depth below the rim for primers. Link to comment Share on other sites More sharing options...

Hmmm, I'll have to look at my Dillon presses. I wasn't aware that you could adjust the punch. Link to comment Share on other sites More sharing options...
George16 Posted July 17, 2019 Share Posted July 17, 2019 Yes, you can raise the primer punch a little bit higher and then just tighten the set screw to hold it in place. On a 550, normal range based on the manual is 1.215-1.220” from the base of the primer slide to the top of the primer cup. I just set the primer punch by a few thousandths higher making it (punch) and the cup seat higher and in turn enables them to set/push the primer deeper into the pocket.

Nathanb Posted July 17, 2019 Share Posted July 17, 2019 You can shim the primer punch on a 650. Link to comment Share on other sites More sharing options...
igolfat8 Posted July 17, 2019 Share Posted July 17, 2019 But my 550 is used for oddball calibers; .380, .45 and .223 while my 650 is dedicated to 9mm. Link to comment Share on other sites More sharing options...

Im not familiar with the 650 since I don’t have one. Can you post a picture of the primer assembly? There has to be a way to adjust it unless it’s built into the machine. Can you not remove the primer slide from the machine? Link to comment Share on other sites More sharing options...
858 Posted July 18, 2019 Share Posted July 18, 2019 You can do all of that and in the end you will have only wasted your time. The XL650 primer seating punch seats primers just fine for ignition on non fooled with guns (assuming your shell plate is adjusted correctly).

goshimu Posted July 18, 2019 Share Posted July 18, 2019 A dirty firing pin spring and/or firing pin channel can cause this also. Link to comment Share on other sites More sharing options...
