I'm looking ahead to next years hunting season, and plan on hunting ina "Traditional Muzzleloader Only" elk hunt. I shoot a .50 cal GPR.I wasthinking aboutbuying a fast twist barrel, because a round ball may not pack enough punch. Before placing my order, I wonder if a fast twist barrel is necessary? Acouple guysshoot "smooth rifles" at the local range, and are very accurate at 100 yards. I've shot slugsin my shotgun, and they are accurate enough at 50 yards to hunt with. Has anyone shot bullets like the Hornady Great Plains bullet or similiar(solid bullets only, no sabots per hunting regs)in their muzzleloaders with slow twist barrels? And if so, what were the results? If I can shoot these bullets accurate enough out to 75 yards I can save myself $200.
