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 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.
