If Wolf shipped that spring with the recoil spring, I would use it. It might have to settle in and develop a "set" at first.
Rechambering rounds. Measure for bullet setback on your loads like we talked about before. Very important. New cases, bullet profile, ramp contour, expander plug diameter and crimp all make a difference. We are pushing the envelope with this load. A reduction in case volume from bullet setback would be bad. That is a another good reason to stay conservative in your loading.
