if i were you i would multi task and take the old barrel along on the range trip. if the new barrel keeps malfunctioning, put the old barrel back on and see what happens.

i checked with those in the know and the firing pin is supposed to protrude .035 to .040 on the recess that the rim sits in. use an "EMPTY" case and place it in the recess to see if it is setting there the way it's supposed to and is free of dirt.

also make sure the feed ramp of your mags is clean and gunk free. they need to feed smooth. if the cartridge skids along the surface it can cause misfeeds and the cartridge might not enter the chamber straight. this may explain the scuffing on your cartridges that you mentioned.

did you strip the bolt and remove the firing pin? a 1/16 pin punch will knock out the pin that retains it in the bolt and then you can remove the pin and spring for inspection.

good luck.
