“Why the reinvention of cartridges? Anymore, it seems rifle buffs neck down and blow out the shoulder of some existing cartridge, then say they can load it with anything from H4831 to Cream of Wheat soaked in nitroglycerin and have magic bullets emerge from the barrel.“
The only relevant 6.5 mm short action round besides the Creedmoor is the 260 Rem, which was also evaluated. The Creedmore has a 30 degree shoulder, which has emerged as the best for accuracy, and the Army ended up preferring it. The Creedmoor is also set up better for long bullets.
The 6.5 Creedmoor has also become extremely popular with civilians, both for target shooting and hunting.
Thanks. Appreciate the explanation. Seems like it’s all about overall cartridge length these days.
There are a myriad of wildcat short action 6.5 round- 6.5 LR, 260 AI etc, they all use a steep shoulder/short neck and are great mid caliber long range rounds. The 260 and 6.5 creedmore are ballistically very similar, as are the rest the of the field of 6.5s.
They also tend to give good barrel lie unlike the long action 6.5s- the 6.5/06 etc tend to last at full power, maybe 1200 rounds from a quality cu rifled Krieger or Obermeyer, much less from button rifled tubes.
