Hello Tony. I read your link to Greybeard. Thats neat. I am racking my brain trying to think of something I can wrap with tape to try this out. I may have to buy a new gun just to do this.
The 44 mag info I mentioned was in response to the 44 mag handi you mentioned in post #5, not the 45/70.
I do have several 32 mad revolvers and a 32 mag rifle. I may try wrapping some .308 110gr bullets and see how those work. They don't shoot worth a darn in my 30-30. I think the twist is too fast.
