Recently I have had [strike]a thing[/strike] an obsession with large bore rifles, and one of my latest acquisitions is a Browning 1885 High Wall, chambered in .45-70Govt. I am currently thinking about purchasing a dangerous game rifle in .458WM/Lott (Mistake No. 1)...do you see what kind of train wreck I am heading for? So I got to thinking (Mistake No. 2)...what about reaming out that wee little chamber to make it a nice roomy .45-120 (Mistake No. 3?). That should allow me to load the rifle with a 450gr. jacketed bullet at about .458WM or even Lott velocities when I wanted a little extra thump (buffalo, large bear, Africa perhaps)...while allowing me to download to .45-70 velocities (for plinking, deer, et cetera). If I decide to ream it out I will be: A. Consulting with a certified gunsmith to perform the work & B. Using .45-120 brass for all of my loads to prevent throat damage and leading. Of course I would love to hear from anyone that has already tried doing a modification like this in a strong modern firearm like the 1885/No. 1/No. 3. Any advice as to how to proceed (specifically with load development)...or have I finally fell off the apple cart? Thank you in advance for helping me to sort though my "eccentric" ideas, Mav.
