I put a moveable trigger shoe on a Wright Allen trigger. Also, made a feed ramp and made a recoil lug. The recoil lug on the original 52 Winchester sometimes isn’t deep enough to do the job properly. Here in lies the problem with this receiver. I added a middle action screw that screws into the feed ramp.

So how was it rebarreling a 52? What barrel brand, twist and length did you go with?
I’ve done enough of them, that it’s pretty easy for me. It’s a Hart Barrel, 16 twist and 26 inches.
