PRS, NRL triggers

[Rob01]

I make every effort to keep my jewells clean at all times.


I also beat the hell out my Jewell triggers and have had but one problem occur with a Jewell that happened during load development and a blown primer. Literally ten of thousands of rounds in temps from -30 to 100 degrees and they’ve always worked.

It’s hard not to have confidence in them.

That’s good you keep them clean. Must be working. Had a buddy that swore by them also until his trigger locked up at the 2012 Snipers Hide Cup in Wyoming and luckily he carried some lighter fluid with him and got it working again.

I'm calling mostly BS on this statement.
I run Jewells on 3 Bighorns, 2 Kelblys, 2 Vudoos, never had an issue,, ever. And I've shot in some horrible crap. This whole Jewell thing has been beat to death with failures. I've seen it happen a few times over the years. It's ALWAYS been attributed to either a WAY hot load/ large firing pin. As far as single stage/ 2 stage, it's a chocolate vanilla thing

Call it all you want but the match that two went down was at Rifles Only in south TX and it was windy and dusty. No hot loads. Glad yours work but wouldn’t run them myself.

I've got three TT diamonds and a BixNAndy TacSport, all single stage. Run them around 1lb. Have seen a LOT of dust and adverse conditions over the years, no issues.

TT diamonds have been really popular for last couple years in PRS but they’re very sensitive to blown primers. There are def guys running hot and blowing up in bad weather. So they’ve been getting a little bit of a bad rap as unreliable, but I’m personally not sure it’s totally deserved.

I run a single stage flat shoe diamond at 8oz in 3 diff guns and have never had a A/D, N/D (yet) which -is- becoming a problem in PRS. We have safety protocols so that when it happens it it should end up in the berm, but I’m def hearing about about ad/md more and more often as guys push triggers below 8oz regardless of brand. You bash a gun on props and slam the bolt fast or shoot in 35F weather with cold hands and people start bumping triggers, shit def happens. If I go down to 6 ounces I can’t get enough feel on my finger pad to cozy up on it before sending it so 8 is my self imposed lower limit.

bix n andy is also popular but i don’t have any experience

After looking up the TT Diamond triggers, in relation to being sensitive to blown primers, I got curious. It looks like they are for bolts guns only. Having shot a Rem 700 for many, Many years, and being familiar with their reliability, how would a blown primer effect the trigger mechanism? In an AR platform a blown primer can end up wedged beneath the trigger mechanism, rendering it nonfunctional. 80's vintage Malaysian 5.56x45 has blown primers back into the action a couple of times. Took it out of rotation and it's range ammo only.
Be gentle, I'm not a gunsmith, just an interested bystander.

I've had three TT AR Diamonds. One just stopped working - got locked up. The other two mysteriously increased their min pull weight after a few hundred rounds.
For two of these, TT was sure I had a 'pressure issue' - i.e., pierced primers. Absolutely not. But, it clear they believe/know there is something about the way the trigger is put together that it is affected with the blow by from a pierced primer.

I have seen a bunch of triggers fail at matches over the years. Jewel no more/less than any others. I have witnessed AD (not ND) with TT, Tubb, Bix. I had a buddy DQ at a national match with a defective TT. They apparently had a batch of lemons and recalled/replaced them. Short answer is maintain & test your gear, especially if you are out west in the dust. A spare trigger in the truck is never a bad idea also. Nothing is perfect.

As to single-stage or 2-stage; I am 2-stage all day everyday.

I haven't taken one apart to see how it fails (they won't replace it if you do). But they are -very- gracious about handling the issue for you if you send the trigger back the first time it happens. They warn you about the the issue and the second time it happens, they're less gracious (as they should be).

If you are blowing primers that much then the trigger is not the problem.
