OP
I can appreciate your zest for the power wagons of the pistol and rifle world. While it is not my thing, I am one of the gawkers when you guys send the pressure wave across the shooting line. Our indoor range allows big bore handguns and I get looks just firing full house 44magnum.
One thing I have noticed is that they seem a bit challenging if you decide to sell.
Have fun and as others have stated reloading will be an absolute must. I started reloading for 357 and 44 due to cost and they are cheap compared to the big boys.
It's always fun watching people's reaction at the range when something that sounds like a cannon comes out.
Thankfully, even if I don't shoot it much, it will always say least make for a good conversation piece. I see no reason I would want to sell it.
