Savage AccuTrigger Questions?? - 10/21/10
I have a Savage with their Target AccuTrigger, which they claim can be set down to 6 oz. pull. However, I have had issues with it "false firing". You get a click, but no fire. I'm sure it is part of the AccuTrigger safety system. The cause seems to be closing the bolt too quickly, but at times it happens even when you close the bolt very slowly. When it happens once, it seems to repeat the cycle a few times. It was pulling this trick on me about 10 out of 50 shots.
So I took my AccuTrigger apart to see what I was dealing with here. I have modified a rimfire AccuTrigger before, but this one is a bit different. The parts seem to be better in quality and finish, compared to the rimfire version. The AccuTrigger leaf is stamped and shows some evidence of not being totally cleaned up. It also sits very loosely inside the real trigger, with lots of side to side clearance. It would seem it may benefit from some spacer washers to center and tighten it up some. Did not do it this time.
I checked the pull and it was surprising lighter than I thought it was -- 7 oz. A couple of questions:
1. The article on the Adjusting the non AccuTrigger that is below says not to put any lubricant on the sear itself. I found this one has a liberal amount of moly or graphite paste on it. What are your thoughts on lubricant or not on the sear? I just put back what was there for now, and used a dry graphite coating on the other parts, as I did with my rimfire.

2. This AccuTrigger seems to have most issues with lock up on closing the bolt. On my rimfire if that happened the blade leaf would immediately go tight indicating a lock up. This one is different. The leaf stays loose, but when you pull the trigger it just gives a click, instead of firing. Any idea what is happening different there? It does not seem to be the leaf that is locking the mechanism. Also, I can't seem to replicate that mode of lock up in the shop. For now all I did was cut a turn off the leaf spring to lighten the leaf pull, but I don't think that is going to solve the problem.
After the minor tweaks described I had the gun out to the range yesterday, and had two "click" lock ups instead of 10. It is probably tolerable now, but I would like it to be more reliable without increasing the pull.
