I've tried Superformance in an 8 twist 22 Creed with 80gr bullets and (so far) all SDs have been high and accuracy poor. It's possible that I just haven't found the right combo, but early results haven't been good.
FWIW - RE17 has produced excellent accuracy and low SDs.
The reason for the question is I have been getting superb accuracy with 75 grain Berger VLD's and Barnes 62 grain TTSX's and would like to venture into the 80's. I have a limited supply of Superformance, thus the question before going heavier.....
