Good article, RIPP. Interesting that the ballistics are quite similar to the .35 Whelen, although with smaller bullet.
Contrary to the COTW listed ctg. dimensions, the shoulder does appear somewhat larger than the Whelen ctg.
more in line with the 9.3x62, ie: .454" rather than the .445"listed. The .445" might/must be a typo.
Seems to me we had some .318 Express ammo in the store in Vancouver & I thought it had the same shoulder dia. as all standard case Ackley ctgs.
