For me so far in my tikka varmint stainless, I have used 140 VLD's with H4350 and RL17. Loaded anywhere from 3.005" to 2.885" which is from lands to .120" off. None will fit in the mag, which is 2.835". I have not tried mag length yet. 8 loads using 40.5gr. H4350, and 39.5gr. RL17, 4 seating depths each powder, largest 3 shot group at 108 yds. is just under 3/4", two under 1/4", 1 at 1/2", and the rest at just under 3/8". I don't know velocity, as my chrony wouldn't work, and I have yet to try seated to fit in the mag, or higher charges. 6 of the 8 loads have the exact same point of impact, the other 2 1/4" to the left. Strange, but I doubt that I will be getting rid of that gun any time soon!
