.357 Magnum shotshells

[Travis Warren]

Good day everyone. Been reloading for about a year and a half on a Dillion 650. I just got setup to reload .357/.38. I was gifted some capsules and shot to make shotshells with and was looking for some reloading information for charge weight with Blue Dot. Any input would be appreciated

Weight the shot cap when it is full, and look for the lightest bullet data for 38spl, and see how close the weights are.
I think 100gr bullet data, reduced by 25%, and a shot cap at 80gr or so would be about right

Thanks Wes. This matches pretty closely to another "rule of thumb" formula I read earlier. Thanks for taking the time.

Check online for data from Speer they are the ones that usually make the capsules
