My goal is to slow them down within safe range and have gun cycle reliably while maintaing a 30-35gr charge.
These are plinkers not hunting rounds
I'm not overly familiar with 458 but I know the Xtremes can be pushed real hard. The 1500fps is a recommendation. A few guys here push them much further with no problems.
If you can, ask Keith Hodgkins. He's a 458 guy.
