I recently made the switch from .45 LC to .45 ACP, so I am pretty clueless on this. I have a Kimber Pro Eclipse II and a Les Baer TR Special. So far I have just shot FMJ factory and commercial reloads....and not a single jam or misfeed. I thought that I would slowly work my way donw the food chain on ammo. What is the most misfeed prone ammo? Looks to me like semiwadcutters because of the little ledge on it.
