In 1925, Winchester introduced the .270 Winchester, previously known as the .270 WCF, based on the 30-03 Springfield case necked down to .277" (6.8 mm). Although the .270 Winchester was not an instant success, within a few decades it became one of the most popular big game hunting cartridges for mid sized game worldwide, because of its relatively mild recoil and flat trajectory within ...
The table below shows how the rounds compare. Reloading data for 200-grain (13 g) bullets for some of the cartridges is not available. Extensive loading data for the .338 Marlin Express is not yet available. The powder used in the Hornady loading is also not yet commercially available as of Feb '09.
A typical .30-30 factory load fires a 150-grain bullet at 2390 ft/s, while the current 7-30 factory load fires a 120-grain bullet at 2700 ft/s. Muzzle energy is just over 1900 ft-lbs for both of these loads, but the lighter weight 7 mm bullet has a higher velocity and flatter trajectory.
These bullets include most Barnes' bullets over 110 gr (7.1 g) and any conventional spitzer bullet of over 115 gr (7.5 g). Hornady's 117 gr (7.6 g) round nose bullet is made for such firearms which have the slower spin rate. Norma loads this bullet in the Weatherby's H257117RN ammunition for owner of such rifles who require a heavier bullet.
The .280 Ackley Improved (.280 AI) was the result of the .280 Remington case modification by P.O Ackley, who pushed out the sidewalls at the shoulder to near parallel and steepened the shoulder angle to 40 degrees in order to increase powder capacity, thus along with increasing the allowable pressure, resulted in increasing the bullet initial velocity by approximately 100 fps.
The widespread availability of .30-30 loads, which can cost less than some other calibers, is another factor. New rifles continue to be purchased and cartridge sales are strong. Because the majority of rifles chambered in .30-30 are lever-action rifles with tubular magazines , most .30-30 cartridges are loaded with round-nose or flat-nose ...
