Some here know that I've been messing around with a 43 Spanish rolling block for the last couple of years. For those trying and failing to get accuracy with smokeless powder, I think I know why and a possible fix. As black powder shooters already know, black powder will bump up an undersized bullet but smokeless will not. The 43 Spanish came into being before smokeless powder so undersized bullets wasn't a problem. With smokeless powder, you have an undersized bullet rattling down the bore and accuracy is pretty much nonexistent. I was pulling my hair out (I have none to spare) trying to figure out a solution and I think I did. Paper patching. It allows me to increase the bullet diameter without increasing the diameter of the bore riding nose section. It seems to work and it's not as difficult as I expected.
