What velocity are you getting for the 210 and 215 gr bullets? If I recall correctly, you're running a 28" barrel?
Thanks -- Todd
28" barrel on mine and its 5C rifling. We are at 4100' ASL. My load is also in Lapua brass. I got 2995 with the 210's and am getting 3035 with the 215's.
I see the rifles vary here with Velocity, but not a ton. I had a Snowy Mountain rifle come across the bench with a 26" that shot 2980 with 77 gr. Most go over 3K with 78 gr. On average they shoot better at 77 and are at max. But on occasion there will be a rifle that is good at 78. If there is such a thing as a common sweet spot for this load, it would be 77 gr.
