My Nucleus action needs a bang-switch

[EchoDeltaSierra]

Hey all... build parts are coming together nicely and I now need to decide on a trigger. The "best" trigger I've shot any amount is my Timney 40X triggers installed on the R700 actions in replacement of the stock ones. I currently run a bit over 2 lbs pull weight and don't think I want or need much lighter. This rifle will be my PRS/hunting/field rifle so I want a durable and weather resistant versus a more bench style trigger. I've also done a fair amount of trigger brand reading and have gone through the thread here by people experimenting with triggers on the Nucleus.

That said... my two main questions:

1. Stay with a single stage or switch to a 2-stage? I run two-stage triggers on gas-guns but have never shot a bolt-gun with a 2-stage.

2. What manufacturer? I wanted a Super 700... but... now I'm considering Huber and Bix'n'Andy, but am curious what others might recommend.

Please just don't toss out your favorite brand... this is specifically for a Nucleus; thus should be a low-maintenance durable trigger that matches the quality of the action.

Thanks in advance.

I have run multiple Timney models, trigger techs, and a jewel. I currently use a Timney CE 2 stage and I don't know how I feel about it. I think I will go back to a single stage. Out of the single stage realm I prefer Trigger tech. Never had one go down.

I went from Jewell single stage to CE 2 stage to Bix and Andy Tac Sport 2 stage. Bix and Andy is by far my favorite.

 

[Danrobberg]

I also shoot a bix and Andy two stage. The tac sport is a fantastic trigger. You can adjust the pull weights on both the first and second stage as well as the length of travel on the first stage.

Have you tested this with a Nucleus action? Have you compared this to a Triggertech?

 

[Chili47]

Triggertech!

 

[BurnOut]

I have a TT Diamond on mine, and really like it. That said, I truly prefer the trigger shoe on the Timney 510/517, and wish that I could get the TT feel with the Timney shoe.

 

[nexusfire]

No I have not. Is there something unique about nucleus?

 

[Notdylan]

FWIW when I ordered my Huber I spoke with Mr. Huber over the phone and he mentioned something along the lines of Ted (Nucleus designer) using a Huber for testing/timing design with the Nucleus. I'm sure the other triggers work great too but I really like my Huber.

 

[ThePretzel]

For the Nucleus action you can't go wrong with a TriggerTech if you want a single stage or a Huber for a 2 stage.

The Calvin Elite triggers have been problematic for many with the Nucleus action, contributing to light primer strikes.

 

[EchoDeltaSierra]

No I have not. Is there something unique about nucleus?

The design of the Nucleus is unique; similar to other actions, but literally unlike anything else.

 

[Lonestar1027]

I use a Bix n Andy Tacsport on my nucleus and love it. No complaints, really digging the adjustability of the 2 stage.

 

[Diver160651]

I have a bunch of Huber’s and a couple of Timney’s that I bought and a bix as people raved about them; But they’ve all been moved to my least used guns.

It’s funny you’ll see a guy raving about a trigger, especially light ones who will rave about a trigger and then you watch them shoot and they squirm behind the gun trying to find the comfort before pressing.

I’m not saying everyone does this, But dang there sure seems to be a disconnect between mating the finger and the final press for a lot of people.

What I am suggesting is that none of us are going to be truly a good guide for what you will ultimately like. Luckily all the hi triggers carry a pretty good resale value

What trigger sear height did you select for use with the Nucleus action; stock or something else?

 

[Sutherlandsd]

My trigger tech diamond flat is nice in my Nucleus. No problems so far.

Could you please elaborate?

I went with the standard height sear.

 

[clyancey]

For what it's worth, I put a Tubb T7T (2 stage) in my wife's Nucleus and it seems to work as well as the T7T I have in my Mausingfield (which has worked excellent in hunting conditions for 3 years). Expensive but I think they are worth considering if your already considering a Huber.

 

[BLKWLFK9]

Right now, I've got a CE 2 stage flat shoe on my nucleus, but I ordered a T7T for my John Hancock. I'm excited about trying out the tubb trigger. That's not to say I dislike the CE. It's a nice trigger for the money. I got it on sale for $160 and it's a hell of a trigger for that money.

 

[1moaoff]

TT Diamond is phenomenal... try one!!!!

Starting to put them in all my rifles.

 

[Northernjets]

Has anyone tried using a Cadex DX-2 in one yet?

 

[ram]

I went with the standard height sear.

Did you measure the distance from the trigger pin to the cocking piece per the sear compatibility table on the TacSport website? On my Nucleus action, the table would indicate a low sear instead of the standard medium sear.

Do you have any cocking on close with the TacSport two stage?

 

[hereinaz]

Huber triggers don't pass the bump test.

I love my 2 stage Huber on my comp Nuke. It has such a clean break and I believe is does have the best shot timing. Such a very nice trigger, but Hubers don't pass a vigorous bump test.

I chose a Diamond TT for my hunting Nuke. Love it too.

The Huber has a little more cock on close than the Diamond TT in my Nukes.

 

[EchoDeltaSierra]

Could you expand on the “bump test” you refer to?

Ram, initially I did not. I was in a rush to get this rifle ready for Gap Grind and just threw it all together(including load development) in about a week. I decided to break it all down again today after you asked the question and measure, and low and behold it looks like a low top sear might actually be better. I'm showing about 4.0mm from top dowel to cocking piece on mine. You? I had no real issues during load development but had light primer strikes on 10% of my shots at the Grind. I'm wondering(hoping) if this is the culprit.
As for the cock on close, there is some but I'm not too worried about it. The action likes to be run quickly, so I hardly notice it. These issues aside, I'm still super pleased with it.

Lonestar, thanks for your reply.
I too measured 4.0mm. I,m trying to decide between the TacSport two stage and the TT Diamond Pro.

 

[Lonestar1027]

I would buy the tacsport again in a heartbeat. Never tried the TT, but I can't imagine being happier with a trigger. The BnA is so adjustable and crisp it's absurd

 

[craigos]

dont buy a geissele - wont work

Per GACS on the super 700 thread, they have the issue with the Nucleus fixed with the new replacements for the recall.

How do you measure this?

 

[ram]

How do you measure this?

With the action upside down and the bolt closed, measure from the top of the trigger retaining pin to the surface of the cocking piece.

anyone running a tubb T7T on a nucleus? since my geisseles are SOL thinking about the Tubb ... am a 2s guy

Craig, I'll let u know once my T7T and JHR arrive. Lol

 

[Skunkworx]

I’ve got mine mated to a t7t. @northern50 runs one on his as well.

Awesome, now if i can only figure out if the new MDT ACC chassis has clearance for the T7T. thanks Skunkworx....

 

[Skunkworx]

That I can’t answer, I’ve got mine sitting an a manners gen 2 mini chassis. It accommodates the t7t with no mods needed.

What trigger is on your most used gun?

 

[PinesAndProjectiles]

I'm running a Huber two stage and I have had zero problems with it. I find that I prefer a 2 stage over a single stage.

I haven't had the chance to try many of the other triggers out there.

I'm sure they are good also. If you can, go to a match and fondle a few of them.

PM me if you’re comfortable. Curious where in MN you are located. This is a project I’m working on with Villiage Pine in Hugo.

BnA tacsport with default sear bar, Calvin Elite 2 stage worked fine on both my nucleus.

Cock the bolt, bump/drop the buttstock on the ground-- click or worse, boom at the worst if you didn't test it...

Safety on or off? Also, how old of a model trigger?

 

[ThePretzel]

Safety on or off? Also, how old of a model trigger?

Safety off. This test is just to make sure that if you're carrying the rifle while it's loaded (hunting, at a match while moving during a stage, etc.) and drop it that it won't go off by accident. It also helps to run the bolt aggressively hard several times once you've adjusted your trigger for the same reason, to make sure that if you start running the bolt unexpectedly fast in the heat of the moment at a match or in the field that your gun won't go bang without you touching the trigger.

I get that part and have years of experience handling firearms in harsh millitary conditions. That said, I’m super mindful of moving any of my bolt guns with safety off and when climbing or doing other more severe activity either open the bolt handle or take the rifle to condition 3.

It’s a fine balance between a field and match trigger, yet precisely what I’m looking for.
