I spent some time trying to improve the bad EB20 trigger by smoothing out rough spots, greasing, shimming and adding a trigger shoe. The trigger shoe is a really nice addition, which I got about 10 years ago from SD custom designs, Steve Darrel? The trigger is still bad but feels nicer to shoot.
I shot it over the chrono it was quite cold this morning but still produced 5fpe. I'll add a hammer spring guide and check the power. The .22 version must sit very close to the limit.
