Well, just ran a few .690 round balls and MAN, ARE THEY HUGE. I compared em' to my .395's and 490's and I can see why frontiersman liked the smaller calibers. You get a lot more balls to the lb. with something like a 40cal then you do with a 75cal and with proper placement the 40cal will kill a deer just as dead BUT it's still cool to have something that'll shoot such a big ball. I'm going to try using the same 85grs of 3fg that I'm using with my shot load(85grs 3fg same measure for shot making it 1 1/8 oz load) and see how it groups. Also, I have to use jean matrial for patches because even the Wally World pillow tickin' isn't thick enough. At a later date I'll get some jean colth or other thicker cotton cloth to use but for now I have a couple blue jean legs that I can use. :thumbsup:
