Q: When does something bigger make sense?
A: When the other stuff gets boring.
For me, it's as simple as that. We don't need to get "Freudian" about it. Shooting all kinds of wheelguns is how I get my yuk-yuks. Sure, they make for a good defense. And yes, I hunt sometimes, but when I go to the range, those big wheelguns are my fireworks. I'm not limited to just the big bores, either, but they sure are fun. I like the arcane and the diminutive, as well. (Dixie Gunworks had this 2mm revolver for sale at one point. You can't image how disappointed I was when I found out that it didn't actually shoot anything but caps!
)
Let me further illustrate my point:
At first, I was happy with .22 rimfire. Then I graduated to rather tame wadcutters out of a .38 special. I thought that would hold my interest. Nope. I played with the .380s, then the wonder 9s, but that got old. Then I bought a .357 with a 4" barrel. That held my interest for a while, until a friend introduced me to Mr. 44 magnum. That somehow made the .357 seem less fun. My brother got into reloading, and had the dies for 357, so I kept asking him to make me ever-hotter loads for it. I got a Dan Wesson pistol pack. I love to shoot it with the 2" barrel and the rip-snortin' rounds.
But, that has become boring. I now have a DW SuperMag in .357 Maximum. I bought a Super Blackhawk in 44 magnum. I saw the muzzle on a S&W 25-5, bought it, and now I have .45LC fever. I'm sure that will develop into a full-on 454 Casull infection by the time this decade is out. And yes, someday I will be shooting .600 Nitro Express out of a Z-Frame S&W revolver, commenting on how tame the Y-Frame loadings were. There is no end to it.
Sounds like an introduction at Muzzle Blast Anonymous, doesn't it?
Since the hunting laws and ever-present government have conspired to make my hunting choices .22 LR, birdshot or slugs out of a shotgun, I will never hunt in this state with any of my hand cannons, or rifles. But, about the only time I care about what someone else thinks is when I see them cringing in the next station at the range, when I fire one of those suckers. That's why I always ask for the station at the end.
If you don't know what I meant by "fireworks", I guess I could explain it this way: In my little corner of the world, it's my little dab of risk in an otherwise dull life. The big boom and flash is a surprise, kind of a like one of those scare-houses on Halloween -- Which I love, by the way. I'm not saying this applies to everyone, but I'm attempting to explain what makes me tick. If I was hunting with one of these cannons, I think I'd pick whichever had the biggest "fun factor", because it is likely the one I will be most comfortable with, and likely the one I would shoot best with.
Is that enlightening, or do I need to stay in a padded room for a spell?
