This is strange. I am confused. Help


--------------------------------------------------------------------------------

Hey guys I have a question, I have been loading for my 445 supermag Dan wesson and been having a blast pun intended. Well to my problem. I have been making some loads up and went up a grain in powder over the last reload and guess what my velosities went DOWN. Before you ask the weather was warmer by about 15 degrees today over the last ones. So why would my velosities go down? I made up several different loads up and noticed that most of my loads went down with adding more powder. I just don't get it. Please help I am really confused.

everything was the same as the pervious load except the powder was from .5 gr to 1 gr more dependant on load.

thanks

Simple: You're "over the hump". Past a certain amount of powder, pressure continues to rise sharply, but velocity stays constant or goes down. Back down before you break something.

In 130 gr 38 Super loads with LIL'GUN the velocity, recoil, and noise, go down with overloads.

In 357 mag 158 gr loads with LIL'GUN, the gun keeps getting louder, and the recoil keeps getting bigger, but the chrono stays the same from 18 gr all the way to 26 gr.

And when I asked Hodgdon about the 38 Super, they wrote back, "of course, the efficiency goes down."
That didn't make me any smarter, it just tells me to accept it.
