Shot this with my Droid so the quality sucks, but man ... I love big bore rifles. This sucker produces about 7,500 lb. ft. when loaded up. Compare that to your average .300 Win Mag around 3,500 lb. ft.
You going to put up the vid of me? LOL Man that gun was fun! I felt a physical adrenaline rush after shooting that thing at a relatively fast pace. I just felt like firing it again, and again, and again while screaming at the top of my lungs.
I like big bores too and regularly shoot a .458 Lott...not close to the power (5800 ft lbs) of the .460 WB though! My "real" big bore is a .50BMG.
What are your ammo costs? I was buying Lott ammo from a well known mail-order company for $94 per box (Hornady 500 grain solid) plus shipping and found the identical ammo at American Shooting range in Houston for $92. I noticed they also had a fair amount of WB ammo although I can't remember what calibers.
