Search 7mm GT on here! It takes some time to from brass, but with 60.7 grains of H4831sc and a 29" barrel, and 180 gr Bergers I am getting a "validated" 3010 fps. and have never shot a group over 1 MOA with any load
It willl consistently shoot .5 MOA with fairly regular .4 and .3 groups, at 300 yds. I would even let you use my reamer
. I really want to see someone else build one but all of my buddies are being cheapskates!
My rifle weighs in around 13# and kicks like a kitten, could be the weight, but even in a lighter rifle it shouldn't be bad. There are also some new 6.5 ideas on here lately that are looking pretty good, 6.5ss and some others as well. If you want a wildcat.
