Sometimes an article appears that just resonates with me, but before I talk about this one I need to clear the space a little.
One of the problems that beset gun manufacturers is that they are, in effect, doomed by the quality of their product. My Swedish Mauser, for example, was designed in 1896 and made in 1906, and after probably several hundred rounds through the barrel — maybe over a thousand, who knows? — it can and does still shoot minute-of-angle (MOA) groups at 100- and 500-yard distances.
So from a manufacturer’s perspective, they produced a rifle that has lasted close to four generations, and counting; there’s no way they could stay in business with that kind of production cycle, even assuming that the number of shooters would moderately increase every year. That’s no basis for a business to operate.
Fortunately, gunmakers are blessed with a restless clientele who are always on the search for the “perfect” cartridge — flatter trajectory, higher velocity, harder-hitting, lessened recoil: you name the goal (or combinations thereof) and there’ll be a market for it.
So it’s no surprise that the manufacturers will come out with some new wunderkind-cartridge that will require a new rifle with a different chamber size, different barrel bore / rifling twist, and so on.
I used to have a problem with this, especially when — as it must — such “improvements” come at the expense of a cartridge doomed to reloader-only status simply by virtue of being old. There’s only so much room on the shelf, after all, and only so much profit to be made at whatever production runs.
The 6.5x55mm cartridge used by the aforementioned Swedish Mauser is a good example of the above phenomenon. That 6.5mm (.256″) bullet diameter has been proven to be perhaps the perfect dimension to create the compromise between performance and recoil for most small-to-medium-sized game (and amply adequate for ahem anti-personnel requirements).
One can play around, of course, with the cartridge casing size and/or length to change the propellant quantity that will slow or increase the bullet’s velocity. So the 6.5mm bullet can appear inside the 55mm casing of the Swede, the 47mm of the 6.5mm (BR) Lapua, the 51mm of the .308 Win (a.k.a. 6.5 Creedmoor), or the 63mm of the .30-06 (a.k.a .25-06 Remington): the list goes on and on.
And that’s just for the quarter-inch bullet diameter. Now take it up to 6.7mm (e.g. the .264″) and OMG 7mm, and all hell breaks loose.
So now you can go and read 6 Dying Rifle Cartridges that Deserve a Second Chance, and see if you agree. Your own choices for redemption can be posted in Comments.
For Readers Of More Recent Vintage, I first talked about this topic a couple decades ago, in Nothing Good Since 1955.
And yes, I know that all the cool kids swear by the 6.5 Creed; we Olde Pharttes know full well that the 6.5 CM is popular only with shooters who’d never shot the 6.5 Swede, which is a superior performer anyway.
In cartridges, as with all things, history is important.
