Hey Les, I initially worked up a good load with the 185vld's myself before going to the 210vld in my wby. The load I had with the 185vld was rem brass, Fed 215GM mag primers, 78.0grns RL22 and a COAL of 3.728 touching the rifling, this gave me 3043fps average. Accuracy was around .5moa. I decided to play with the 210's and discovered that I could push them nearly as fast as the 185vld's in my particular rifle. The 210vld load was rem brass, 215GM mag primers, 77.0grns RL22 and a COAL of 3.730 touching the rifling. Velocity was 3,000fps. These bullets have a long bearing surface and are "sticky", I think that's why I could run the 210 almost as fast. With the much better B/C of the 210, it was a no brainer ballistically to go with the 210. You may not get the same results in your rifle however. I was not concerned about fitting the shells in the mag, I could have one in the chamber and one would fit down, with these bullets that's all it should take. Not sure where to get ballistics for the HSM stuff. These are one shot one kill bullets if you put them where they're supposed to go.
