I started shooting 2000 MR this summer based on Speer data. It easily bested RL15, Varget and H4895 for velocity with comparable accuracy in my 20" 1:14 Ruger. Getting 2630 with 66 grains and a 250 Speer HC. 67 Grains gets the 225 Sierra going about 2665 and hitting to a similar POI. About 1 MOA for the Sierra and about 1.5 MOA for the Speer. Brass seems to be holding up well. A 3" zero at 100 gives a pretty useful "hold on hair" trajectory out a fair ways with those velocities. Planning to fill my antelope tag with the Sierra.
