GetAwayDriva Posted September 2, 2014 Share Posted September 2, 2014 Anyone having problems with light primer strikes? I get it with cheap shells like Walmart federals and other no name brand, as well as higher quality Rem STS and Win AA. It is not picky, it will do it with any kind of shell. I have had burrs removed from the bolt and contact surfaces. Everything has been polished and cleaned up. Firing pin hole checked for debris. Firing pin polished. What else can I check or do?

Dan Sierpina Posted September 2, 2014 Share Posted September 2, 2014 How stock is the gun? By any chance was the hammer spring altered to lighten the trigger pull? Link to comment Share on other sites More sharing options...
GetAwayDriva Posted September 2, 2014 Author Share Posted September 2, 2014 Mods made to loading port. Nothing done to hammer spring to lighten trigger. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted September 2, 2014 Share Posted September 2, 2014 What does the firing pin protrusion look like with the bolt and carrier out of the gun? Is it going completely into battery? Link to comment Share on other sites More sharing options...
GetAwayDriva Posted September 4, 2014 Author Share Posted September 4, 2014 It is .073 and appears to be going fully into battery. Link to comment Share on other sites More sharing options...
openclassterror Posted September 4, 2014 Share Posted September 4, 2014 When you say it happens with any kind of shell, are you saying it happens with high base shells too? Or just any kind of target load? It is sometimes hard to tell if it is going fully into battery because if it isn't, the hammer usually pushes it home when it falls. If you let the bolt partway forward by hand and then let go, does it still close on a shell? If it runs ok with hot loads, the higher bolt velocity may be slamming it home. What percentage of the time is it occurring? Link to comment Share on other sites More sharing options...
GetAwayDriva Posted September 4, 2014 Author Share Posted September 4, 2014 We don't shoot any high brass shells, just target loads, slugs and buck. It will do it once out of 100 rounds or so. At the very least, it will do it once every time I shoot it at practice or at a match. Sometimes a lot more, but at least once. You can close the bolt as slow as you want to and it will go into battery on a shell. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted September 4, 2014 Share Posted September 4, 2014 Are you lubing the cam pin? What does the pin look like, is it worn or deformed? A friend replaced the cam pin on his older Versa Max tactical with a Benelli M2 cam pin. Link to comment Share on other sites More sharing options...
openclassterror Posted September 4, 2014 Share Posted September 4, 2014 +1 on that. A lot of people have had issues with the soft cam pin wearing into funky shapes that compromise function if not well lubed. By any chance has a gunsmith checked the headspace? It is a one-in-a-million chance that Remington shipped a gun with excessive headspace, but if the rim isn't supported the firing pin just shoves the shell forward in the chamber. Swapping out the hammer spring is a cheap try, and may solve the issue. How many rounds through the gun, and has the problem existed from day one?

GetAwayDriva Posted September 4, 2014 Author Share Posted September 4, 2014 Cam pin is not worn or deformed and has been well lubed. I bought the gun used from my brother in law about 9 months ago. He did not shoot it very much. If I were to guess, I would say I have probably put a thousand rounds through it. Will have to check on the headspace. Thanks!

KungPfoo Posted September 4, 2014 Share Posted September 4, 2014 I was having a more severe light strike issue, probably once every 50 rounds, and changing out the hammer spring fixed the issue immediately. Another possibility is the spring that provides back pressure on the firing pin to stop slam fires is too strong. If you're ordering a new hammer spring you might as well order a enw one of those and replace them at the same time and see if it fixes the problem.

openclassterror Posted September 4, 2014 Share Posted September 4, 2014 If it has been stored hammer-back for long periods, the hammer spring idea is starting to sound like the right track. Contact Remington and see if they will send you one before spending the money on a headspace check. Average gun shop charge for a headspace check is $50, and many shops who do not specialize in shotgun work don't even HAVE a 12ga set. +1 on the firing pin return spring as well. Both together should be well under $20. Link to comment Share on other sites More sharing options...
GetAwayDriva Posted September 4, 2014 Author Share Posted September 4, 2014 Thanks everyone for the help! I always drop the hammer when I store the gun, but I don't know what my brother in law did when he had it. It sounds like some springs are the answer. When inspecting my hammer, I noticed that the hook that contacts the disconnector is chipped so I have a new hammer, hammer spring, and firing pin spring coming. Also ordered a cam pin too, just in case. Hopefully this will solve my problems! Link to comment Share on other sites More sharing options...

GetAwayDriva Posted September 10, 2014 Author Share Posted September 10, 2014 My parts came in and it appears Benelli hammers are much better quality than rem ones. Installed them and for some reason bolt is much easier to cycle. Now just gotta test it out! Link to comment Share on other sites More sharing options...
mpom Posted September 10, 2014 Share Posted September 10, 2014 Easier to cycle possibly due to either to smoother surface or change in angle where new hammer contacts back of bolt. Doubt new hammer spring is weaker than one that is being replaced. Link to comment Share on other sites More sharing options...
GetAwayDriva Posted September 12, 2014 Author Share Posted September 12, 2014 How's this for a kicker? It is worse now with the new parts. 6 boxes of shells total, 10 that didn't go bang. 1 box of rem gun club shells ran fine. But the other cheap shells did not. The federal Walmart shells were the worst. I had 3 in a row fail to detonate. I did not try any sts or AA. I checked to see if the bolt was locking up fully on the shells that failed to fire and it was. We did radius the sharp edges of the breech face quite a long time ago and it ran fine for a while.

mike cyrwus Posted September 12, 2014 Share Posted September 12, 2014 (edited) did you physically see light strike indentations on the primers of the shells, or are you saying "light strikes" because a round is in the chamber and didnt go off when you pulled the trigger?

GetAwayDriva Posted September 12, 2014 Author Share Posted September 12, 2014 Yes I did physically see a light firing pin indentation on each round. It isn't very deep and it is off center.... Much closer to the edge than the center. I have a picture but have no idea how to attach.... Link to comment Share on other sites More sharing options...
GetAwayDriva Posted September 12, 2014 Author Share Posted September 12, 2014 Don't know if this will work, but I have tried to attach a photo of one shell that did not go "bang" Link to comment Share on other sites More sharing options...
Buddy2 Posted September 12, 2014 Share Posted September 12, 2014 Replace the firing pin spring with a benelli firing pin spring that should fix your issue. Link to comment Share on other sites More sharing options...
GetAwayDriva Posted September 13, 2014 Author Share Posted September 13, 2014 I did replace the firing pin spring with a Benelli one. So I swapped out the trigger group with another VM trigger group. Ran my trigger group in the other gun. No light primer strikes. Ran the other gun's trigger group in my gun, multiple light primer strikes. So that tells me it is not the trigger group.

Buddy2 Posted September 13, 2014 Share Posted September 13, 2014 You could have a burr on the barrel luggs. Try swapping the bolts than you will know if it is the barrel or the bolt. You might have a firing pin out of spec. Link to comment Share on other sites More sharing options...
MarkCO Posted September 13, 2014 Share Posted September 13, 2014 On a round that does not fire, put back in chamber and see if it hangs at all. The win cheap loads have large variations in rim and case head diameter. If the chamber has not been throated, that might be the issue. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted September 13, 2014 Share Posted September 13, 2014 (edited) Mark, She indicated light strikes were happening with STS and AA ammo besides the cheap stuff. This was in the original post. Edited September 13, 2014 by Dan Sierpina Link to comment Share on other sites More sharing options...
