In my experience, Powerbelts may shoot great but aren't designed to be pushed as quick as I want in a modern inline with some of the new powder substitutes. They are too soft, and if pushed to quickly have a tendency to grenade.Why bother with sabots for elk. A 295gr Powerbelt in .50 is an elk killer. Or if you want heavier, step uo to the 348gr. The Powerbelt bullets are underrated in my opinion.
