I love the accuracy of my 7mmSTW, but kinda surprised I am not getting better performance. Only getting a hair over 3100fps with 160gr accubond with 80gr of H1000. Some claim to get that with 78-79. Its a sako 75 26" barrel. Might try RL25.
I found the newer h-1000 extreme to be much milder than the original h-1000.I had to add 2 to 3 gr more to acheive the same velocity.
