Oh yes, thank you very much kind sir. Just logged on to do that. I was posting from my phone and didn't want to fidget on it for too long.
Now this is for .44, but Rattlesnake Jack has used this in a .45-75 and .45 Colt with the same success. However, making these in .32-20 may prove somewhat fiddly.
If anyone else has any more ideas, don't be shy.
