Not to beat this issue to hard, because sometimes people can make to much out of it, But because those guns have brass frames you want to shoot them with lighter powder loads , and avoid the heavier loads. Shooting the heavier loads can stretch the frame..
Beautiful firearms, the sheriff's model is just butt kicking nice,, That metal will get a nice patina with a few cylinders fired off...
Thanks!! and the manual recommends around 16 grains as a good load to start with but also gives a max load. It was 25 or 30 grains IIRC.
