But can he slap a mag in that fast with a gun that has no wide beveled mag well added onto it??? Those race guns sure have all the amenities to help a competition shooter load quickly. I'm sure with some practice even you could load a magazine that fast into a beveled magazine well.
I've seen autoloaders that the clip won't even fall out of that fast.. Tell you what I saw in Europe years ago. Guy, American, was shooting trap with a pump shotgun. On the doubles, he'd fire one, keep the gun mounted and eject with his left hand and catch the MTY AND drop it into a pouch on his belt and still make the double! The gun never left his shoulder!
Anyone who shoots a sabot bullet has had the problem with loading the next round with a dirty barrel we have all struggled with it.
Between muzzleloader shots I have done some research and testing on my own to find out what works for me for the next shot. I have been using a product called bore butter and when the muzzleloader is just sitting around I leave it caked in the barrel for protection. Have also found that if I lube my sabots with bore butter they really slide nicely down the barrel....
