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.

.45 ACP: The standard US pistol round for about 75 years. Typical .45 ACP loads are subsonic. [54].45 Colt: a more powerful 45-calibre revolver round using a longer cartridge. The .45 Colt was designed for the Colt Single Action Army and adopted by the US Army in 1873. Other 45-calibre single-action and double-action revolvers also use this round.
The .45 ACP (Automatic Colt Pistol), also known as .45 Auto, .45 Automatic, or 11.43×23mm [1] is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol.
It is essentially a .45 ACP case, necked down to .357, resulting in a cartridge similar in form to the earlier 7.65×21mm Parabellum and 7.63×25mm Mauser cartridges. It was created to be a low recoil target cartridge that would function reliably with multiple bullet types, FMJ to cast lead wadcutters without the feeding problems that straight walled pistol rounds sometimes exhibit.

According to Guns & Ammo magazine, Performance is on a par with the 10 mm, yet pressures are much milder. Factory ammo is loaded to +P .45 levels, but the lighter bullet weights make recoil comparable to .45 hardball loads. Felt recoil is a little sharper but still very controllable. [5]
For comparison, Hornady's 9249 load for the .500 S&W Magnum cartridge offers slightly less energy at the muzzle, achieving 2,868 ft⋅lbf (3,888 J) by driving a 300 grain (19 g) FTX bullet at 2,075 ft/s (632 m/s). Buffalo Bore's loading for the .500 S&W cartridge offers much less energy at the muzzle, achieving only 2,579 ft⋅lbf (3,497 J) by ...
The .45 ACP, when loaded up to maximum standard pressures (none of these loads were listed as +P) will outperform .40 S&W in most weights. A quick look at the .45 GAP (which is loaded to .45 ACP +P pressures) shows that the 185 grain bullet is pushed to 1090 fps, for 488 ft. lbs. of muzzle energy; .45 ACP +P should be equal to or (since it can use a slightly slower, less dense powder) slightly ...
The .460 Rowland / 11.43×24mm is a rimless, straight walled handgun cartridge designed in 1997 [1] by Johnny Rowland and developed in conjunction with Clark Custom Guns as a derivative of the .45 ACP [2] with the goal of producing a cartridge which can achieve true .44 Magnum [3] ballistic performance and be fired from a semi-automatic platform.
