Re: Do you shoot or reload 6mm 08
I don't own a rifle or load for the 6mm-06 but here is some info that may get you started.
The 6mm-06 is based on the most popular cartridge in the world. It is a simple process to neck down 30-06 (or even better .270 Winchester) brass to accept .243" diameter bullets. Trim to 2.494". The result is a 6mm-06 case.
Like all wildcats, there is no official SAAMI pressure limit for the 6mm-06, nor is there a set cartridge overall length. In this situation, the chambers of rifles can and do vary, which affects pressure and velocity--a fact that reloaders should never forget.
The 6mm-06 became popular shortly after the introduction of the .243 Winchester in 1955, which made a good selection of 6mm bullets widely available to reloaders and wildcatters. Certainly experimenters had necked down .30-06 and .270 Winchester cases to accept 6mm bullets long before 1955, but it was the .243 Winchester that really brought the .24/6mm caliber into the limelight. The 6mm-06 has gained in popularity ever since, and has become one of the most popular wildcats. The introduction of ever slower burning powders has made this once seriously over-bore cartridge a viable proposition.
The 6mm-06 is at its best with the heaviest bullets in the caliber. The 100 grain and 105 grain spitzer bullets are a particularly good choice for medium size big game at long range.
The 105 grain bullet can be driven to a MV of around 3200 fps. 6mm-284 data can be used as a starting point for working up 6mm-06 loads. As always, and especially with a wildcat cartridge, start with the minimum load and work up slowly, checking carefully for signs of excess pressure. Verify results with a chronograph, and stop testing immediately if you get unexpected velocities. (If you are reloading for a wildcat cartridge, a chronograph is a necessity.)
At 3100 fps the ME of a 105 grain bullet is about 2240 ft. lbs. The 200 yard figures are 2663 fps and 1653 ft. lbs. The trajectory of that load looks like this: +1.5" at 100 yards, +2.3" at 200 yards, 0 at 258 yards, and -3" at 305 yards.
