P.O. Ackley was a notable gunsmith famous for developing wildcat cartridges from parent cartridges like the 30-06 Springfield. For many of the wildcats listed above, and several of standardized commercial chamberings based on the 30-06 cartridge, there are "Ackley Improved" versions with sharper shoulders increasing case capacity.

A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

The .30-06 cartridge, with the 173 grains (11.2 g) bullet was called cartridge, .30, M1 ball. The .30-06 cartridge was far more powerful than the smaller Japanese 6.5×50mm Arisaka cartridge and comparable to the Japanese 7.7×58mm Arisaka. The new M1 ammunition proved to be significantly more accurate than the M1906 round. [22]

The .35 Whelen is a powerful medium-bore rifle cartridge that does not require a magnum action or a magnum bolt-face. The parent of this cartridge is the .30-06 Springfield, which is necked-up to accept a bullet diameter of .358 in (9.1 mm). This cartridge is more powerful than its parent, especially in killing power on large game.
Headspace positioning of rimless, rimmed, belted and straight cartridges Several different rimmed, .22 rimfire cartridges, which have a uniform forward diameter, and which have headspace on the rim, allowing any length of cartridge shorter than the maximum size to be used in the same firearm Firearms chambered for tapered rimmed cartridges like this .303 British cannot safely fire shorter ...
