Jewell trigger springs?? Help!

[wyo]

Just recieved my Jewell for my model 70. Its factory set for one pound and they sent springs B & C. I want to install spring B. The directions don't say where the provided springs install. If I want to change out the A spring for one of the others how does one do that?? The directions don't give that info. Any experienced help would be appreciated.

The trigger spring installs in the trigger spur between the adjustment screw,number 3 in the attached instruction drawing) and the lower rear bushing. Just remove the adjusting screw and current spring and then put in the desired spring, reinstall the adjusting screw and set for the desired pull force.

Spring force ranges,typical):

Spring A: 8.0 to 56.0 oz.
Spring B: 2.0 oz. to 16.0 oz.
Spring C: 1.5 oz. to 3.0 oz.

Thanks Fred for the info. I thought, as I studied the instructions closer, that #3 was where this adjustment/change was made but wasn't sure. Your answer confirms that and I appreciate the help. As far as installing went, it just required enlarging the hole in the reciever slightly and pinning on the trigger. Everything functions flawlessly. I'll have to enlarge the holes in both stock and guard but I wasn't nearly as concerned about that as I was the fit of trigger to action.

Be sure to check for the "safety" that becomes a trigger problem.

It is often necessary to slightly reshape and polish the striker ramp for proper safety function. As it comes from the factory, with the safety "on" pulling then releasing the trigger could result in the sear not resetting,engaging the striker lug) so that when the safety is subsequently moved to "fire" the striker could release and the gun would fire.

This problem also occurs with the factory trigger. Particularly those made within the last two years of production by Winchester.

Please do not be offended by the following cautions. I am not presuming any particular skill or experience level on your part. There will be others reading these posts that could also be affected and/or influenced.

I do quite a lot of trigger replacements and adjustments for a variety of shooters with different intended uses for their rifles. IMHO I generally do not recommend trigger force settings below 3 lbs,48 oz) for field hunting or 1 lb,16 oz) for informal target or varmint hunting from a rest.

Below the 1 lb,16 oz) trigger pull force level is the realm of the serious and experienced target and benchrest shooters that are firing from stable rests. Below about 3 oz pull force it becomes difficult for all but the very experienced shooter to maintain both trigger contact and safe control.

The 2 to 16 oz range of the "B" spring puts you into that realm and therefore places a serious burden on you for added safety in your own use. Also be reminded that should you allow others to "try" your rifle you should also be careful to warn/caution them as to the very low force and energy required to fire that rifle as apposed to what they are used to and expect.

Very good point Fred. I let a shooting buddy shoot my 7mm Rem Mag
700 after installing a 2 oz. trigger. Even though the rifle was on the rest it went off long before he was ready even after me telling him to beware of the light trigger pull. A couple of months later I had received my 6 X 47 Shehane with the Jewel 2 oz. trigger or less installed in it and this same guy wanted to shoot a pop bottle filled with water at 600 yds. with it. He had looked thru the scope and lined up on the bottle and turned his head to say something to me. He touched the trigger while looking towards me. I suppose with it being 17.5 pds. it lay still because the bullet actually hit the pop bottle just below the cap. You have to continuely remind your partners about the light triggers. They have no clue as to how light you are talking about. Bill

The advice is appreciated. I tested the safety as per instructions several times and have been dry firing it repeatedly with a snap cap to become familiar with the trigger. The setting from Jewell is 1lb.. Excellent, crisp feel and it works, as mentioned before, flawlessly. I feel fortunate that it was basically a drop in fit to the reciever at least. I've already opened up the inletting in the stock and modified the Williams trigger guard and it wasn't really hard to modify either of those parts. Fairly basic file and dremel tool work etc.. Again thanks for the helpful insight Fred.

Since you both seem to be interested in the best triggers possible, you might find these reports of interest:

Trigger Commentary

Firing Cycle

Several of us trigger nuts spent an inordinate amount of time and money over three seasons of "spare" time designing equipment, shipping it back and forth and doing the testing that supported these findings.

Great read FredBohl!!!

Thank you for the comment. It is always encouraging to think someone actually reads my reports and finds sufficient value to have made the effort worthwhile.

To all that have read those reports:

Due to the untimely passing of one the fine shooters that was a tireless participant and benefactor in the projects, both projects have gone on indefinite hold.

However, we would certainly welcome reader feedback,both supportive and critiques) on both subjects. If there is sufficient interest we may try to continue the research with the intent of eventually generating enough data to suggest some possible equipment or technique improvements.

I also thought the articles a good read. I'm printing them to save.

When someone wants to shoot any of my guns with a less than factory trigger, they must dry fire the gun successfully a couple times before I hand them a round. Also the gun must be in firing position on a bench/rest.
