Re: Lighter Loads
try 200 LSWC (hard lead tends to work better at lower velocities than soft) and Unique. make up 10 each of loads starting with the min and going up in .3gr increments. Unique has less of a spiky perceived recoil than the faster burning Bullseye. also 200gr is less zingy than the lighter 185 bullet. 5" bbl will burn up most all the Unique powder.
when shooting min velocities the gun and the cases are going to look and be 'dirtier'.
is it arthritis thats gettin to ua? i'll use 6.2gr U and Missouri hard LSWC. YMMV
below that and accuracy suffers. above that (6.6 feel factory) kinda hurts my hand for longish sessions. good luck.
