So the standard 223 only gets 3050 fps with a 55 gr bullet...
3350 fps is now 22-250 velocity...
Only need a slightly longer magazine such as the 6.8 spc...
Ain't marketing wonderful?
First off, an 18" barrel is used to get the 3350 fps, a 20" barrelled 5.56 with M193 will get 3275 fps routinely. My 22" 223AI Montana gets 3600 fps with a 55 gr bullet.
Never seen a 22-250 get less than 3600 fps, granted a 24" barrel with a 55 gr bullet.
The 6.8 magazine doesn't have the spine in the middle which makes more difference than the slightly longer OAL.
I thrilled for the effort but I think it's nothing more than marketing. Am I wrong?
