Can anyone tell me if there is a diff between a regular CZ mag action and the action being used in their 505 chambering. Did they just open up the bolt face or is it new.

same action they just opened it up to accomodate the big gibbs case.

you made me go get mine in 416 Rigby and check. A 505 Gibbs loaded round is just a "hair" too long. The box must be 3.8" oal. The round slipped into the magazine, but I had to take it out the bottom.
