What is the typical groove depth seen on conical paper patch barrels and what are the limitations on the bullets ability to obturate the bore?
I have a .408 land, .427 groove rifle that shoots 289 grain bullets. I'm having trouble locating a hollow base bullet but a flat base is avaliable.
I'm worried the soft lead bullet won't be heavy enough to slug up and fill the rifling.
