R3;

I was just hoping that IMR4227 would have a little more velosity for the amount of powder that is dumped into the 38spl case.
All 38 loads were tested in my L frame 357 magnum for safty and the at near or compressed loads were just under or at the start of a +P velosity.

You can use 50% less powder for the same velosity if you switch to w231 powder and also have less powder flakes dropping out of the brass and revolver when the cylinder is opened.
I actually had to stop testing one day when a "Standard load" from the IMR data, actually froze up the cylinder in my snub nose form the powder flakes getting into the cracks of the revolver. Removing the yolk screw was the only way to get the revolver to work again.
It just needs lots of pressure to burn clean and this is not going to happen in the 38 spl loads in the manuals.
Looks like the lawn is going to get nice and green this coming spring............................

later.
