The parts came this morning and I got them installed relatively easy. The extractor detent has a little notch that only goes a particular way. If you're looking at the side of the parts, the notch goes toward the inside of the bolt and the solid side is outwards toward you.
The mag spring and follower works right now. Bolt stop screw stops the bolt like it's supposed to.
The extractor pulls the shell out of the chamber now, but doesn't eject it. I think that is due in large part because the broken extractor on the other side is allowing the shell to twist some while you're pulling back on it and when it does slip out of the extractor, it tensions toward the inside of the receiver. I think that will fix itself when I'm able to get the right side extractor later on.
Will try to shoot it later this evening to see how it does. For the time being, I loaded up 10 shells all with titegroup and 1-1/8oz shot with the lightest published load I could find. 15.0 grains, Winchester primer, supposed to be 8,000 psi and 1090 fps. That's about 2500psi below saami max for the 12 ga.
I'm mainly starting out as low as I can just to proof check everything at first to see how it does before stepping up to "regular" low brass velocities. I'm pretty sure this load was meant for cowboy action shooting with those old guns anyway and in fairness is pretty anemic, but the gun needs to earn my trust.
I loaded up five shells with #6 shot (one is the test load that I won't be holding and just to see if the gun frag's, and depending on how it does, I'll shoot the other 4 into a paper target to see how it patterns. And I have five other shells loaded up with scrap shot that I have salvaged ranging from #7 to 9 shot just to see how it does.
Less powder, more lead...shoots far, kills dead. Just hopefully not on both ends
Going to try to get some pictures and/or video later this evening. I think it'll be fine.
