so update, the skb action is clean and lightly oiled. The same shells function fine in my Rizzini BR550, which is also a inertia trigger and the skb functions fine with factory shells. I am just going to go back up 1 die on my MEC press. My gunsmith says I could put a lighter spring in but it doesn't look easy to access and not worth the gunsmith $ in my view.

This ain't a dress rehearsal , Don't Let the Old Man IN
