Reading an old magazine that I inherited from dad, there is an article in there about a World record Grizzly was shot with .45 cal. Though it is smaller then I would take after griz. , it obviously did a good job.

A buddy shoots the Wolverine ( an older model) and he has no complaints. All be it our experience is limited to mostly knight and TC MLs. The longer the barrel the more powder that gets burnt, creating more speed, and the more accurate it is suppose to be.

If interested I can track down the mag with the griz story in it for you and email it to you.
