Because the 270 Winchester bullet is slightly narrower than the 7mm-08 bullet (.277” vs.284”,) and they have the same mass, the. To keep this race as fair as possible, we used Nosler’s AccuBond Long Range bullets in each rifle and kept barrel length and rifle weight identical. Read this blog post for a more in-depth explanation of Maximum Point Blank Range and its advantages for most big game hunting. The distance at which this bullet then drops 4 inches below point-of-aim establishes its maximum point blank range.
This means we zero high enough to keep all bullets from flying no higher than 4 inches above point-of-aim at any distance. To conduct this race we have pushed 150-grain bullets to top velocities in each rifle, zeroing each for a maximum point blank range for an 8” diameter target. Once again we’ll go to the judges’ score cards, but first… How much difference will this make in ballistic performance? Obviously the 270 will propel that bullet a bit faster than will the 7mm-08. This means it will hold 62.8 grains of water while the 7mm-08 Remington is limited to just 47.8 grains when both are topped with 150-grain bullets. The main point is this: the head and body diameters of both the 270 Winchester and 7mm-08 Remington give both the same storage capacity except the 270 case is. (But who wants to go around bragging up his favorite “seven point two one three six em em?”) 284” bullet, commonly known as a 7mm even though. At any rate, the 7mm-08 Remington is merely the 308 Winchester necked down to accept a. Historians say Winchester engineers actually used the 300 Savage, a 1921 release, as the parent cartridge for the 308, but if you compare the dimensions of all three, you’ll see that Savage likely based its 300 on the 30-06 case which was itself based on the 7x57mm Mauser which sprang from the 8mm Mauser… Cartridge development is an incestuous business. First, the 30-06 was shortened to make the 308 Winchester. The much younger 7mm-08 Remington (a 1980 release) is also related to the 30-06, but a couple of generations removed. It’s basically the 30-06 case necked down to hold a. The famously flat-shooting 270 Winchester has been around since 1925.
We can shorten the gentleman's wait time with a quick ballistic comparison right here, including some handling, weight, and recoil differences between these two excellent mid-power cartridges. A subscriber to my You Tube Channel (Ron Spomer Outdoors,) requested a 270 Winchester and 7mm-08 Remington comparison.
