Weird trigger delay? ***UPDATED***

So this is pretty weird. Brand new build. It's a new Bat Action with a new Jewell trigger model Hunter Varmint Rifle w/no options, one pound pull.

There is this bizzare half second delay when you pull the trigger until it strikes the round!!!???

Now it gets weirder... I can not seem to feel it when I pull the trigger with NO round in the chamber. :o

I have this same trigger on another rifle and it does NOT do this?

Thanks
 
Re: Weird trigger delay?

Ok... little more info. I found an email that I did not pay attention to from my gunsmith that built this:

"The trigger seems to time with a little cock on closing. This is not adjustable on this action. If it should bother you, either the cocking piece or the top lever on the trigger has to be modified. "

I'm not sure if this is what I'm experiencing or not, or what this means. I have a call into the gunsmith.

Donovan- yes Tula Magnum primers. And first time ever using Tula.

Milo- Not sure never experienced anything like this.

Thanks
 
Re: Weird trigger delay?

What Donavan and Milo said is the first thing that comes to mind. Two other things come to mind
that I can think of - 1. is if the cocking piece is catching the trigger housing on the way in. You can check that by removing your bolt and look down the channel in the action that the cocking piece travels down and look to see if the trigger housing is protruding out into the channel at all. If it is you can usually just take a brass punch and lightly tap it back where it belongs.

2. The trigger to cocking piece fit is off a little. In this instance I would have a gunsmith look at it that knows how to properly fit it.
 
Re: Weird trigger delay?

Looks like you posted while I was posting.

Question- If you hold the gun muzzle down and let the bolt drop does the bolt stop on the action or does the cocking piece stop the bolt on the trigger?
 
Re: Weird trigger delay?

Also, check the firing-pin protrusion - on several BAT actions, we have found protrusion, at 0.46-.048", to be less than the specified 0.052-0.55". On my BAT HBR rifle, with Wolf primers, this proved to be a deal-wrecker! ;) On several recent builds,pals of mine have experienced the same thing - too little protrusion, thus, inconsistent ignition, including hang-fires.

Bolt stops on action.

Just realized that my Rem 700 bolt assembly tool does not fit this BAT.
 
Re: Weird trigger delay?

The more I understand about hangfires and the Russian primers the more I think that is what this is. I'm going to try CCI magnums next weekend.

Thanks
 
Re: Weird trigger delay?

I'd talk to the smith to start with, it really shouldn't have left the shop knowing something was awry. Then look into the load.
 
Re: Weird trigger delay?

One other possibility. If you are shooting in cold weather and there is any oil in the bolt that can and has caused slow firing pin drops. I sold a Mauser 96 built in California and sent it to Montana in the winter and he called complaining that it mis-fired on every round. He degreased the firing pin and inside of bolt, left it dry and problem solved.
By the way, in all of my match rifles it is the cocking piece that stops the bolt first.
 
Re: Weird trigger delay?

I have ugly savage and I can feed them cheap wolf primes. With a pretty gun maybe its like a pretty woman nothing cheep.
First I would look a the primer strike. If it is too lite check a fired case against one that you have fired. Excessive head space will do that. Other problems have ben addressed by others. Merry Xmas Larry
 
Re: Weird trigger delay?

sounds like you have a timing issue between trigger and bolt: get it fixed ASAP. I'd call BAT first. They have different trigger hangers to time the trigger and it sounds like your smith may or may not be aware of this.
 
Re: Weird trigger delay?

It almost sounds like too much sear engagement,meaning when it is released it is on the ragged edge and finally trips or the over travel is also set to short and the same thing happens.

It coule simply be an ecvess of trigger / sear engagement?

I think the BAT has the trigger fixed by mean od a screwed hanger?

If the case, I suggest to check placing a card shim between hanger and receiver and try cycling.... Or simly lppsening progressivelu the ganger screws.

If problem solved, the sear height is to be altered, or a permanent shin made.

FWIW

Several years ago (more than I care to admit) I had the same experience with a custom built 22-250.

I was led to believe (mistakenly BTW) that better accuracy could be achieved by using small rifle primers in cases of this size. At that time, Remington made 308 cases that used small rifle primers so I decided to try it.

After forming up a few cases by simply running the 308 cases through the 22-250 sizing die (BTW, those were the softest cases I've ever seen; they were so soft they felt like beer can aluminum) I used 38 grains of W-760 and Win small rifle primers. It sure was a surprise the first time I pulled the trigger. There was a weird delay in ignition that felt like a hang-fire or maybe something wrong with the trigger. Like you, I checked the trigger and firing pin and could find nothing wrong. Every round acted the same way. After going back to my normal loads with large rifle primers the problem went away.

I concluded that the faulty ignition was caused by using small rifle primers in a case that was originally designed for large rifle primers. Use of ball powder may have also contributed to the problem. Most shooters agree that ball powder needs strong ignition.

Needless to say, those twenty small primer cases went in the trash and I have had no problems with my 22-250 since.

Hope this helps. Let us know what you find.

Good Shootin' !

No hangers, this is in a chassis - AICS.

Magnum primers in .338LM

Thanks

I have not heard from the gunsmith yet. Sure hope it's just this box of Russian primers.
 
Re: Weird trigger delay?

Now that you mention it's a 338 LM, if it's a hangfire, I'll bet it's not enough powder in the case. You never mentioned what powder you're using.

Like I said before, you need to eliminate the hangup first, get it out of the equation, and you don't want that anyway.
If the smith couldn't fix it the first time, he may not be able to on a return.
