I had a really good conversation with a co-worker today about all of the various calibers that dont really ad anything to the realm of ballistics and we decided most were created as just an excuse to sell more guns and ammunition. For example,
Just the opposite, most were designed to captue a very special niche...a niche you might not be part of. Some guys will say a 223 and a 220 swift are redundant, others will say a 220 swift allows them to reach a tad further, and they are right. Now if you don't sap prarie dogs often enough, these might seem redundant to you.
The various short action magnums that dont really offer anything new to ballistics per se as compaired to their big brothers. The only reason possible for their existance is to boost sales of short action rifles.
It is quite reasonable to introduce 'the same thing just a little different'
Without that concept, we'd have 30-06 and 357 magnum and that's it.
Lots of times these 'pretty much the same but a little different' are addressing shortcomings in the original...like non-belted magnums, because there is no reason for a belt on most magnums.
or a cartridge solves one shortcoming, but inadvertantly causes another one, so then a 3rd comes along that addresses both issues. To the outsider this may seem redundant
And the latest the 30 remington ar. Its just a short action 308, why not just build a 308 ar?
Just speculating here but COULD IT BE DUE TO THE FACT IT CAN BE UTILIZED IN THE AR-15 RECEIVER WHICH IS MADE BY 100 DIFFERENT MANUFACTURERS AT VARIOUS PRICE LEVELS AND QUALITY LEVELS, NOT TO MENTION THE 100,000 OR MORE IN PRIVATE HANDS ALREADY AS OPPOSED TO THE AR-10 RECEIVER WHICH IS MADE BY LESS THAN A DOZEN MAKERS, IS MORE EXPENSIVE, AND A LOT LESS ARE ALREADY OWNED BY PEOPLE?
All this can be quite confusing, which ones are better which ones can you even find? In the ammunition shortage we face today, perhaps in an effort to sell more guns the manufacturers have really come up short. If they had left it alone there would be more ammunition. Its a lot harder to make 2 calibers than it is one, and keep them in inventory.
Really? You are complaining that it is confusing? Heck, if you froze cartridge development some time back in 1920, it'd still be confusing as all get-out.
There's a solution to this. Two solutions in fact. #1 LEARN MORE #2 BE SATISFIED WITH WHAT YOU HAVE AND DON'T WORRY THAT THE GRASS MIGHT BE A TAD GREENER ON THE OTHER SIDE OF THE SHOOTING RANGE
Finally, we've had thousands of different overlapping cartridges for 130 years or so. We've only had an ammo shortage now. The two items are totally unrelated.
You know what would fix the ammo shortage? BAN GUNS.
Just because something would fix the ammo shortage, doesn't mean it is a good idea
