I am on a mission to try and build a suppressed 10/22 that will faithfully cycle when using CCI Quiet 22LR ammo. We all know that this ammo is really weak, but I want to try to build something that can shoot this extremely quiet ammo.
I've done all of the polishing of the bolt, rounded the back of the bolt to help with the hammer resets, changed to a quality extractor, installed a Kidd buffer, new bolt spring for sub sonic ammo and deburred the receiver so the bolt is slicker than dog slot in the receiver.
Two questions:
1 The bolt seems to meet a lot of resistance when it hits the hammer. Would/could I install a lighter hammer spur spring? I know this could cause light firing pin hits on the cartridge causing misfires.
2 Could I mill some of the bolt material away (only in non-critical spots) to hopefully lighten the weight enough to allow the resetting of the hammer?
The firearm tries to cycle, but I think the hammer strut spring is so strong, it's not allowing the hammer to reset. So both option may have to be done to accomplish my goal.
Any other recommendations?
