Jewell trigger problems

[Nader]

Steve,
I'm with Jerry on the sear engagement screw( the one closest to the muzzle,you know, the "Boom" end of the barrel, let's see if we can mis-interpret this). There is a rather loose screw holding this adjustment in place,no lock tite or anything, and if you drive your rifle around enough to different matches eventually it will vibrate loose.Easy fix ---big results.

That's strange...

"Loose screw"? Stange; all my Jewell triggers have nylon coated adjustment screws so as to eliminate the requirement for "locktite" or any other material to hold the screws after adjustment.

Thank's Virg,
I'll send mine back to Jewell and have them "nylon coated". I'll tell them that you told me about it.

Here's a quote from the Jewell trigger manual; note the bold section (I em-bolded it):

"ADJUSTMENT PROCEDURES (BR and HVR)
The trigger has been adjusted for most applications when shipped. Personal preference, however, may require adjustment on one or more settings.
All adjustment screws are filled with Nylon inserts to maintain their set positions. The use of external locking compounds is not necessary.
Screw (1) sets sear engagement (in = less sear engagement).
Screw (2) sets overtravel (in = more overtravel).
Screw (3) sets pull force (in = more pull force).
Initial Adjustment Procedure:
1. Ensure that rifle is unloaded!!!
2. Cock action, turn screw (1) inward until action fires. Back screw out approximately 3/4 turn.
3. Recock action, turn screw (2) out until it contacts tab (12). While applying pull on the trigger shoe, turn screw inward until action fires. Turn screw inward another 1/4 turn.
4. Recock action and measure pull force. Turn screw (3) in for more pull force or out for less pull force. Do not exceed specifications for pull settings.
5. Operate action for your particular method of shooting and adjust as needed.
Note: Rapid firing practices may require slightly more sear engagement or pull force to prevent unwanted firing.
Cleaning: Flush after each barrel cleaning with lighter fluid. The use of lubricants is not recommended.
SAFETY (OPTIONAL) BR and HVR
The safety, when applied, rotates a cam (14) to a position that pushes the sear of the upper level (Fig. 1) off the sear of the trigger shoe and blocks movement of the operating parts, allowing the trigger shoe to move freely. The safety cam is spring loaded to either the fire or safe position, as selected. Rotation of the safety cam is made possible with either a single, bottom activated lever, or the top activated multiple-link arrangement
Care must be taken on installation that there is positive clearance between the levers and stock, as some stock or trigger guard material may require trimming. Ensure that the safety levers can operate to the full range of travel."

Hope this helps,

Virg,
I'm good with that information and sincerely appreciate your input.In common, real practice however,the sear engagement screw will not hold it's setting over the years and will need to be checked and reset( especially if the bolt begins to sporadically decock on closing,or begins to slam fire when the bolt closes).A very slight turn usually fixes the problem for a couple of years.Trigger weight of pull( the spring is the culprit in this case,this screw usually stays put) wont hold consistant over the years either and since this works in harmony with the sear engagement it should be checked and adjusted as well. Many guys( I used to be one of 'em) run these adjustments way too light and get burned when something changes and the gun goes off when closing the bolt.A little more sear engagement and a little more trigger weight seems to make my guns shoot better. It certainly makes them more reliable.
Just tryin' to save Steve a trip to the gunsmith here,it's a pretty basic -quick fix and then he'll know what to do when it happens again a few years from now.
