I replaced the crappy trigger on my Rem. 700 AAC-SD with a Timney. Great trigger pull now, but occasional light trigger strikes with old Nato Ammo (1982). Is it possible that the installation or adjustment can be causing light strikes? We tried the ammo in another similar but stock rifle and the ammo fired.

Re: Can a timney trigger cause light primer strikes?
I had the same problem last time I went to the range with my .308 with APA Genesis action(Defiance). I got the light primer strike,but used the same bullet with my friend .308 and it fired.
The newer version has a longer disconnector or something like that. APA swapped out the newer version and the problem went away.

Re: Can a timney trigger cause light primer strikes?
Call Timney and make sure you have the right sear. There is a long one and a shorter one. You need the one you don't have now. LOL.
Or you can bump the firing pin spring up to a heavier weight. Not the preferred option though.

Re: Can a timney trigger cause light primer strikes?
email timney and ask for the longer sear used for R700's. they will know what you need.
longer sear in rear, factory sear in front. the longer hump is what holds the cocking piece/firing pin to the rear more. providing a harder strike.

Re: Can a timney trigger cause light primer strikes?
This is interesting I have had a couple lightstrikes/failures to fires with an SPS and Timney, never knew about the sear. Pulled the firing pin and it looked like an investment cast p.o.s. with poorly machined off casting flash, I polished it, have yet to shoot it and see if it helped anything.

cock the firing pin, it should stick out past the bolt shroud on the rear of the bolt. if it looks like this cocked it will cause failures to fire. this pic is of the rifle in cocked position with timney.

Re: Can a timney trigger cause light primer strikes?
Hey Wrench,
I have a 700 with a timney.
WHen I cock the firing pin My bolt shroud is pretty much flush. It probably just sticks out over flush. Is that usable or should I call timney and get the longer sear?

Re: Can a timney trigger cause light primer strikes?
Wow, been having the exact same problem!! Installed a Timney about a year and a half ago, and started having some misfires. Looked at the bolt when cocked as mentioned above and it is flush with no protrusion. Timney here I come......
Thanks all

Re: Can a timney trigger cause light primer strikes?
Has anyone tried the U designated triggers for a 700? U is supposedly for a defiance action and has a longer sear and a aesthtically nice normal size trigger shoe.

Had this problem with two rounds at the range last weekend. Haven't had time to inspect the bolt internals, but I suspect I've found the culprit here. Avmech, I'll probably be right behind you in line getting the trigger worked...

Re: Can a timney trigger cause light primer strikes?
Wish I would have seen this before selling all my M118LR because if light primer strikes
The lot I had shot very well with the highest velocity I have seen from my gun.

Thanks for the pic wrench. My bolt looks exactly like the one pictured, just flush with the shroud.
Just to be sure, I took apart the bolt, but it looked good and only needed a cursory cleaning. No J lock, dirt or other obvious nonsense.
I installed the trigger myself, but I've never disassembled or adjusted one. Is it pretty easy to put on the new sear or would it be better just to have Timney install it?
Thanks for the help.

Re: Can a timney trigger cause light primer strikes?
If you already have a Timney 510, you will want to have them send you a "U-Sear". If you are ordering a new trigger, you will want to ask for a 510-U.
The U designates the new model sear that parks the firing pin closer to factory spec and allows correct energy transfer to the primer w/o changing to a heavier spring.

Re: Can a timney trigger cause light primer strikes?
Can anyone provide some insight on swapping out the new sear? Does Timney send instructions or do they want you to send the trigger for a swap? Will it be necessary to reset the pull weight?
Pics or a you-tube link would be appreciated. I haven't been able to find anything.

Re: Can a timney trigger cause light primer strikes?
the sear is easily replaceable. look for the pin the sear is hinged on, using the proper sized punch, push out the pin from left to right. you may need to slightly tap the punch. and watch out while punching it out, it may end up running into the safety lever on the right side.
then just put the sear and pin back in the trigger assem. and tap the pin flush on the right side.
and watch out not to lose the sear spring under the sear.

Terry,
When looking at Timney's website, they list the 510 for the Remington 700 action and don't list the 510 U. I am still a little confused. I am trying to order a trigger for a Remington 700 and want to order the correct one. What action is the 510 trigger for?
Thanks,
Al

Re: Can a timney trigger cause light primer strikes?
Cuban Crock, I just contacted Timney. The new sears are already on their way to me.
I think the best thing to do would be to call an order on the phone. That way you'll get exactly what you want, pull weight and all.
If you want to look online, you want the 510U for a R700.

Re: Can a timney trigger cause light primer strikes?
Well, just order the 510-U for my daughter's Remington 700 .223
Just had the stock dipped in the cheetah pattern. She is running a suppressor on it as well. She is pretty pimp for a 7 year old.
I'll post pics when it is all done.
Thanks for the assistance w/the trigger.

Re: Can a timney trigger cause light primer strikes?
Awesome Cuban!!!! Bringing her up right, that is great. Let us know how it works out, I will do the same with the sear.

Re: Can a timney trigger cause light primer strikes?
So, upon returning from the range this afternoon, in the mail is an envelope from Timney with a sear. Different shape to it, install it, and lo and behold, the firing pin is now sticking out approximately a 1/16 of an inch, the same as on my buddy's VSF. Pop a primer in an old case, chamber it and pull the trigger.......................the indent is much more than before!! Sure looks like the sear was the ticket. Will report back after the next range trip, hopefully next week.
A big thank you to those on here that mentioned the different sears and a big thank you to Timney for standing behind their product!!

Re: Can a timney trigger cause light primer strikes?
resurrecting from the dead, but is it possible to only have this problem with a certain type of ammo/primer? I've ran 400+ rounds FGMM without prob, tried some different ammo and had 4/20 light-strike

Are you sure thats a 510-U? I was almost certain Timney said the U model was for Defiance Machined actions only. The 510 was for Remington 700's and clones.

I had the same problem with my 510 purchased a few years back. I only had issues when shooting ammo with hard military primers. When I switched back to FGMM it ran fine.

Re: Can a timney trigger cause light primer strikes?
I'm glad I saw this. The AAC-SD I sold to a LEO that was going to use it for work had a Timney in it. I never had any light primer strikes in the little bit I shot it but I surely don't want him to have the same problem if he has to take a shot with it.

Yes. They said they wanted $27.50 I told them I'd get back with them, as this thread led me to believe it was no cost.
Correct me if I'm wrong, but the difference between the "U" sear and non-U sear is not documented at distributors and resellers. I don't really feel I got the wrong sear because of my own stupidity or ineptitude. If I were an idiot and ordered the wrong stuff, that's on me.
