I just picked up a Mark X Mauser in 6mm and it will be what i carry in September on a Goat hunt. I am looking at using 100BTSP Power Shok or possible a 100gr SST depending on what shoots the best. This rifle has a 26" tube any ideas on the velocity gain? I was thinking maybe 100fps. Visited the ranch yesterday and saw a couple 15" and one buster 17" or better. This rifle is also a heavy barrel.
