I really like this, and the general idea has floated around between my ears before. However, the practical side of me gets in the way by reminding me that my SBH Bisley in .454 can be loaded down to .460 Rowland levels (most of my loads are around this level anyway) and the gun isn?t that much larger. Also I can pick up a conversion kit for my Kimber for a bit less money to play around with the round.

Keep the updates coming, I love these types of projects!
