As expected, .690 balls shot better than the .678 balls I used initially. Most accurate and regulated load increased from 80 to 90 grains which is plenty for the old gal.

I have only used 2f goex. Wonder if 3f would better replicate the powders they used back in the day. I may cut back to 70 grains of 3f and try that. No real reason to as it shoots fine now. Just curious I guess.
