Considering both measures. For the next session switched over to Warne lever actuated QD steel rings and Loctite on the base torx screws. I don’t have a competent GS within easy driving distance and don’t want to send the rifle away at this late stage. We’ll see what solution I can rustle up.

Since you mentioned the Thunper, I happened to run across a box of 338 Lapua brass in the shop yesterday and got this photo, just for perspective on ‘other’ 458 wannabes.

450 Rigby on the left, 460 G&A in the center and an unaltered 338 Lapua on the right.

Spent time time stamping the first 10 cases as “460 G&A” yesterday. Will post some pics of the stamped bases when I finish a few more. Need to turn out 30 stamped, formed cases to load cartridges which will pass muster upon arrival in Zim.
