Just tried some 444 Marlin Leverevolution rounds in my 30-284. As long as the rim was set in the groove of the cartrige under it the bolt picked it up fine, except for the last round. The rim seemed to hang up on the mag lip.

Didn't notice you wanted to stay with 45 cal until after I posted this, sorry.
