TeleCaster I get it. I don't look at the 264WM as a cartridge for high round count. Better things for target shooting like a 6.5Creedmoor,260, or 6.5x55.But the 264 is a wonderful hunting cartridge.
So no I don't view all cartridges through the lens of a target shooter or hand loader.
But I do like to poke a little fun(all good natured) at folks who think some new invention from the factories is truly "new" and "cutting edge",when in fact most of them have lineage that can be traced back to the first half of the last century,but are hawked as the latest and greatest with a few minor tweaks,better powders,and modern bullets.
Even the cutting edge 6.5 Creed evolved based on reshaping the 250 Savage case;and people were necking down and blowing out 404 Jeffrey cases to 30 caliber a long time before the 300 RUM saw the light of day. Short magnums go back to the 1950's, when some smith blew out 348 Winchester cases,cut an extractor groove in them,and necked them to various calibers.At least a couple of boutique 7mm Magnums today are nothing more than derivatives of a case design dating back to 1912 or thereabouts.....talk about anachronisms! LOL!
Belts served a useful purpose for some of our most useful and effective BG cartridges, likely invented without giving a thought to target shooters and hand loaders.Who cares about them? If the companies depended on the hand loaders to stay afloat, they couldn't remain viable.
So I chuckle when savants comment on the latest stuff,declaring it so good that other stuff be relegated to the scrap heap. In a sense most everything you can fit in the magazine of a bolt action rifle out there today is an "anachronism", in a sense.
