Just some info as I was trying out the Comp Electronics Pro Digital. It was 12 noon and 93* F. Not a cloud in the sky.
Ten feet from muzzle. So FWIW here are some numbers.
Guns used SW M 640 2 1/8 barrel and a SW PC M 327- R8.
First the 357 data.
Handloads of 158 gr LSWC using 10.0 grs of Blue Dot. Not my favorite but trying to use it up. It works well at full loads.
From the 640 snub:
Avg 1136
ES 61
SD 22
A lot of "spitting" Maybe a mag primer would help but that's why I don't like Blue Dot.

So what does all this mean? I have no idea but it was fun.
Actually, I see no reason to carry the 357 mag loads as they are just to hard to control and follow up shots. I seem to like the Remington Golden Sabers 125 gr 38 Spl +P
Based on a previous thread you can see where the increase in barrel length of 3" made a 141 fps difference on my loads of the 158 gr LSWC. They where very nice to shoot out of the bigger gun.
