This is always a fun topic.
I purchase vegetable wads for over the powder, and gas checks for over the shot fron Sage Outdoors. Great people, great service.
I use a similar load in 327 brass. 2.5 or 3 gr of Titegroup, veggie wad, fill the case with #12 shot and crimp a gas check over the top. The pattern will cover a paper plate at 10 yds with a four inch revolver.
I also bought the components in 41 cal but have not loaded any for the 41 yet.
