I recently purchased a 7mm STW with a 26" barrel.I was curious what others are shooting in theirs.I've tested H-1000 in mine @ 80,81,82,83,and 84grs. with a 150gr. bullet and they all shot very well.I didn't have my chrony set up so I don't know what my velocities where,but I'm going to try out 83.0grs. of H-1000 for my 140gr. bullets and 82.0grs. for my 150gr. bullets.
