However, on the contrary to what some competitive shooters and sportsman believe, and as mentioned above, for reloaders there are quite an array of bullet sizes and shapes to choose from. Bullet weights from 125 gr to 250 gr are offered by premium bullet makers such as Nosler, Sierra, Barnes, Woodleigh, Swift, Hornady and other major manufactures.
Measuring the power factor is a quick and easy way to measure recoil, but has some drawbacks. While the power factor measures the momentum of the fired bullet, it doesn't take into consideration the firearm weight or the contribution from the ejected propellant gases which together makes up for the total recoil impulse from the firearm.
A bullet at 125 gr in the .277 Wolverine caliber will stay supersonic at greater ranges than the 300 BLK, when comparing the same bullet weight and construction. To use the .277 Wolverine to fire a heavy sub-sonic bullet for short range, factory-loaded ammunition can currently be found using 175 gr bullets.
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.

Despite the weight, recoil is significant and shooters must be sure to choose components (i.e., scopes and bipods) that can handle the force. The sheer size, weight, and power of these rifles make them rather impractical for hunting use. SSK only manufactured three of these rifles and as of 2014 no longer produces the ammunition. [1] [4]
Bullet energies for .380 ACP loads vary from 190 to 294 ft⋅lbf (258 to 399 J). [12] The table below shows common performance parameters for several .380 ACP loads. Bullet weights ranging from 85 to 95 gr (5.5 to 6.2 g) are the most common.

Critical cartridge specifications include neck size, bullet weight and caliber, maximum pressure, headspace, overall length, case body diameter and taper, shoulder design, rim type, etc. Generally, every characteristic of a specific cartridge type is tightly controlled and few types are interchangeable in any way.
