The way I look at a 357 maximum chambered barrel is one you can shoot:
38 special target loads
38 special standard
38 special +P
357 magnum
357 maximum
All out of the same barrel ! That covers a lot of different rounds and there is no greater variety than 38/357 ammo and components .
Anything from paper target loads to hog and deer hunting loads can be easily covered .
I will admit , I could probably do everything I wanted with 38/357 magnum barrel ...it would be nice to have the 357 maximum option there if I wanted it .
