I'm convinced that every rifle round that comes on the market now days is redundant, just marketed to boost sales. I mean, you just HAVE to use the latest and greatest short magnum. You are inadequately armed with a normal old .30-06 or .30-30 or .308 or what not.
Well, I don't even keep up with all the short magnums. I used to be on top of every development in firearms and some of 'em had merit, like the short action light rifle craze that beget the short magnums in the first place. I love my little M7 Remington, light and handy. But, that's a rifle, not a caliber. Everything that needed doing got done as far as calibers in North America are concerned IMHO. I ain't interested. I have reams of ballistic charts for my firearms and have compared the latest and greatest and know my limits afield and frankly, my .308 will kill anything I wanna kill to my range limits shy of 400 yards. Yeah, my 7 mag is a little flatter and lays down one heck of a lot more energy out at range, but I hunt nothing bigger than deer and hogs.
I could live without that 7 mag, but I thought I was going elk hunting when I bought it and the biggest caliber I had at the time was a .257 Roberts, so it was a good purchase at the time.
In my old age, I've settled on my calibers. I'm not enticed by the latest, greatest stuff. I'll probably not buy another rifle, but if I do, it just could be a lever action .30-30 because I don't have one and they're traditional. It's almost like a handgun collection that is missing a 4" .357 Magnum revolver not having a .30-30 lever in my collection. But, truthfully, I love that M7 so much in .308, I doubt I'll ever use anything else in my rifle collection for hunting. That one rifle gets it done for me. They make it in short magnum calibers now. I still prefer the .308. Why would I need more on hogs or deer? Hell, I could elk hunt with the .308, not a bad choice, really, for elk to 300 yards with a Barnes bullet. I don't need no stinkin' short magnums. Considering what I hunt and the ranges I hunt 'em at, an accurate .30-30 is really all I need. My hunting needs were answered in 1894, yet every year the gun rags tell me I need more.
Ah, marketing....
