Real quick.......can anyone tell me how the 6.5 creedmoor compares to the 6.5 swede????
Thanks Trystan
SAAMI MAP specs are one difference: 6.5x55 = 51,000psi, 46,000 CUP 6.5 CM = 62,000psi, no US CUP standard
Cartridge length is another: 6.5xx = 3.150" 6.5 CM = 2.825"
Within pressure standard limits, achievable velocities for 129-130g bullet are about the same according to Hodgdon: 6.5x55 = 129g @ 2827fps, 45,300 CUP (98.5% of SAAMI MAP) 6.5 CM = 130g @ 2735fps 59,500 psi (97.5% of SAAMI MAP)
The 6.5x55 with long/heavy bullets is best used in a mid-length (7x57mm) or long (.30-06) action while the CM was specifically designed for a short (.308 Win) action length.
