When I couldn't find a Jewel trigger for one of my Sako's, and finding a Canjar single set trigger was like looking for chicken lips, I installed a Timney and adjusted it to right at 1 lb. It installed easily, adjustment was also no bother, and it passes the bolt-slam test with no discharge.
Since then I've put them in two other rifles and find them to be completely reliable and well made. Another excellent option is the Jard triggers. I've got four of them in my Cooper rifles, all set at 10 ozs, as they're only for my bench guns used for live varmint shooting.
