I read that some folks load 180gr bullet in a 38 Special case with what seems to be at 357 velocity/pressure range. I understand that this is done, so they can chamber the cartridge into a 357 lever rifle.

I would like to here comments from folks in this forum.

TIA,

YEP just back off on the go powder a bit(not with 110 or 296) and have fun. a good rule of thumb is to look at the diference between 38 loads and a 357 load with the same powder and velocity and use about that much less from a magnum load.

WARNING--OVER CURRENT MAXIMUMS---USE AT OWN RISK.

With that out of the way: Start out with around 11 grains of 2400 under that 180, I have worked up to 13.5 grains(carefully-with a chronograph). This was an old Elmer Kieth load.

Works well in all my guns-HOWEVER they are ALL chambered for the higher pressure 357. These loads are stiff enough, I wouldn't even THINK of launching them out of something like a k-frame 38 or the like.


Have fun-But work up CAREFULLY.

Some .38 special brass is NOT up to .357 pressures... Don't use a gun you like, wear gloves and safety glasses.
