So what you're saying is, if Remington had created the 260 Rem with a faster twist and ammo that actually shot well with bullets that people actually wanted to use, it would have been popular. Yeah... so, if Rem had done the 260 right (basically making it a Creedmoor), it would be so popular today that elitists would be trashing it as the hipster cartridge of choice and the Creedmoor would have never needed to be developed!
Instead, the 260 was spec'd with a 1:9" twist, a 2.035" case and a 2.8" COL, meaning it wouldn't properly stabilize the heavy-for-caliber bullets (not talking soft points here) and you'd have to cram bullets down in to the case to make COL. Obviously hand-loaders can seat bullets out to whatever COL they want and most LR 260 shooters build with a faster-twist barrel.
The point of the Creedmoor was to make something in a factory configuration where you don't need to buy a custom fast-twist barrel or hand load to be able to make use of high-performance projectiles. It worked and has become the best selling cartridge of the last few years.
Do any of the LR shooters here that trash the Creedmoor because they like the 260 even use a SAAMI spec, 1:9" twist 260 Rem? Or use factory ammo?
