Chronographed following load thru newly acquired 16 inch 357 R92. Could only fire 3 shots (must appease the neighbors, you see):
170 Gr. Speer Uni-cor FP, 13.3 gr. Alliant 2400 in Rem brass, 1513 fps avg.
1st shot - 1515, 2nd shot - 1513, 3rd shot - 1511
sd - 2
Not a large sample, granted, but looks hopeful. Primers rounded, no flattening whatsoever. These bullets have a very large meplat and just ever so slightly "kiss" the bottom of the chamber mouth, not enough to see in some cases. Looks like room to increase charges, but want to load some for accuracy testing at 1513. This bullet doesn't look to be manufactured anymore in this config, altho the same prod. # still exists in a bullet with a little more ogive and smaller flat (tip). So I'm going to hoard these and try to get 50 good loads to keep on hand for game. Would love to get more of this one, tho.
