Timney triggers work, but they don't have the quality parts like a rifle basix, Shielen, etc. The quality of the sears, etc. allow a good trigger set up that won't wear and change. Especially important the lighter you set your trigger.
My timmney got very very light with time (about 200-300 rds) I became concerned it would fire upon release of the safety. It took me about 15 minutes to take the action out of the stock and find the right size allen wrench and then which screw adjusted weight. It has been fine for about another 200 rds. Maybe I should check it before it is time to go deer hunting.
I am new at the rifle building game. I have a 7MM Rem Mag barreled to a M98 action. I added a Timney trigger to it several years ago. It has operated pretty well. The rifle will shoot a 3 shot group under 1/2" at 100 yds. I used the 140 gr Barnes X Boat Tail bullets. I did have some trouble with the lock nuts backing off and the set screw working forward. This gradually increased the trigger pull tension and hte groups opened way up. I found that it was my own fault. I was in testing mode and failed to put any "Thread Lock" on the lock nuts and set screws once I had the desired tension, creap and backlash set.
I am building another rifle (6MM x 284 Winchester) on the M98 action. I am in the trigger selection process now. I am open to any suggestion that you guys have? What would you recommend. The only names I am familiar with are Boyd, Timney, Jewell and Kanjar (Unsure of the Kanjar Spelling). I only have personal data on the Timney. I would prefer a trigger with a wider shoe.
