A labor intensive 6.5mm that really screams???
I thought some of you would like to know what I held in my hands this afternoon. A gunsmith in Idaho showed me a 6.5 that just might be worth the effort of case forming. It was called a 6.5 lrt (his initials). It was a 25 wssm necked up and the shoulder was blown forward a bit and given a 45 degree angle. It was tight necked and throughted for the 142 MK. He said his charge was 49 grains of RL22 and it was 105% density. He also claimed that he just finished chronographing it and it was shooting the 142 grain bullet at 3050 with just a 26" barrel! This load produced a standard deviation of 7, and shot a .5 inch group at 200 yards. I thought it sounded pretty efficient because my 6.5-.284 pushes the same bullet with the same charge at 3100, but it has a 30" barrel. This short fat thing might actually be working like they say it does!
If it's not far, it's boring.
