I'm loading .38 Special using Bullseye powder in .357 magnum cases to shoot in a Colt Trooper Mk 2. Do I need to make any adjustments to my load from .38 reloading tables? Do I just use .38 data with the exception of loading to .357 magnum COL? Am I right in assuming that with a larger case the same charge will result in less pressure and reduced bullet speed? It's been a while since I loaded pistol rounds and my records of what I did in the past are AWOL.

Thanks for your help!

You're correct, BUT to assume you will get equal accuracy as your .38....uh, uh. You'll have to work up an accuracy load. You might try magnum primers as well.

A Chronograph will become your best friend.
Slug your barrel, load for target velocity, have fun.

BTW Colt's and S&W M52s usually have a .355 bore.

You would want your cylinder throats (assuming a revolver) to be the same or larger. Frequently, there is a constriction where the barrel screws into the frame. You can cure that with firelapping.

I would go with swaged wadcutters for this type shooting.
