I think I'd do a 6mm Vias instead of the 6mm Remington case necked down to 22 caliber. First of all it's way overbore, and will probably eat barrels rapidly. A 6mm Vias will push a 70 grain bullet faster than a .220 Swift can push a 50 grain bullet if that matters much. The Vias is simply a 6.5x55 case slightly shortened (about a millimeter), and inproved to something like an Ackley design. There is a 22 Vias as well. By the way a 6mm Vias shooting 70 grain bullets is good for about 4,000fps in a 26" barrel, but really starts to show it stuff with bullets 85 grain and larger. It ought to easilly push a 105 grain Amax to 3300 fps. I shoot a 6/250AI out of a 26" barrel, and it will push a 105 grain Amax to 3100 fps (max). Needs another .075" of neck length, or better yet just ream the chamber with a 6mm Ackley chamber reamer setup for the 250AI headspace. That barrel's gonna last a long time. Of course you can do the samething with that reamer and make it a 6x55AI, and make your cases out of generic 6mm Remington cases. Use a 1:8 twist barrel that's about 26" long
When you start to look at 500 yard + ranges, you want to be thinking about the 6mm bore size anyway, and after 700 yards you need to be looking at the 6.5's
