I'm probably going to work up some handloads this winter and see if I can get a 125 or 150gr SST or Ballistic Tip to shoot consistently under 2 moa.
I've had pretty good results with 1680 powder in a PSA KS-47, and also in a Ruger #1. Both would easily stay under 1½" for 5 shots. Using the Ruger I took one deer with the 123gr Hornady SST, and also some hogs with the Nosler 123gr, which were available at their Pro Shop for a while. Both are .310 bullets, and both are pretty frangible on game. I'd like to see somebody make a bonded 123gr bullet that holds together a little better. At some point I'll try the various 150gr .311 bullets in the Ruger, which has a long throat.
FWIW 1680 also works well in the .218 Bee, and subsonic in the 300 BO.
