Well I sure am glad I have a Ruger No. 1 in .375 H&H and .458 Lott. Heaven help me if I had to defend my caliber choices all the time...
If I had a .375 Ruger I'd have to be talking about just as good as or shorter actions and barrels.
If I had a .405 I'd have to continually mutter "Big Medicine...San Juan Hill!"
If I had a .416 Rem I'd have pressure myths to dispell and belts to excuse while babbling about being as good as the Rigby.
If I had a .450/.400 I'd be trying to figure out what Woodleigh bullet to use while disputing the actual caliber of the gun and claiming it is so pleasant to shoot compared to X.
If I had a .404 I'd have cult members hanging out around the house chanting ".404...magic bore" and one squeaky voice protester on the street with a sign saying .423 that nobody liked.
If I had a .450... it'd be outlawed, unobtainable, and not as good as a .470.
If I had a .458 2.4" I'd always have someone dragging it down by calling it a .45-90 and there'd be a slew of questions about the voodoo involved with modernization of an ancient cartridge.
If I had a .458 Win Mag I'd be like Cool Hand Luke, constantly shakin' it in the bush to keep the powder from clumping.
Since I have the .375 H&H and the .458 Lott, I need not burden myself. My bases are covered and I can can sleep at ease knowing I have two Swiss army knife calibers.
So if we were to return to topic...shoot it well with a .458 and 450-500 grain bullets...loaded to accuracy...keep shooting it...run after it and shoot it again. Pose for picture. Not terribly complex.
