RE: Patches......why not?
I'd say maybe if shooting a soft lead(patch needs to bite the bullet) with a light load(fast twist at speed would be harder to transfer spin to the bullet). The high end charges would probably burn through a patch unless using a wad/buffer material. I think it would pretty hard to find a patch/bullet combo that would load easy enough with a large bearing surface of a bullet compared to a ball where just the line around the circumference is wedging the patch in the rifling
sorry justcaught the slow twist part
