Anyone have an idea of what velocity (ballpark) you'd get from the following 40S&W load:

40S&W - 180gr Lead TCFP w/4.2gr of Win231

I've been loading this round for a few years and don't recall where I got the load data from.... its not in my reloading books. Or maybe someone has a load range for 180gr with Win231?

Thanks

The Lyman 49 manual lists the lowest w231 40 S&W charge for the 175gr TC Lyman @ 4.3 gr.

They list a velocity of 796 fps for that load.

Don't have the 4.2g data but have the 4.5g W231 - had it going 927-938fps, 1.125" oal, using Federal small pistol primers. Fired from a G22 with a lone wolf barrel.

SO?

I use 3.8gr 231 w 180 Rainier's for IDPA mouse farts.
they squeak by in the low 700 fps for 128 to 130 pf.
they function in stock glocks.

they are so soft its almost cheating!

Yeah, I'ld like to see them ammend the IDPA rules to allow only factory equiv. vel ammo. It seems the point of IDPA is to run realistic combat scenarios & realistic guns. Then they allow mousefart loads, makes no sense to me. When I do shoot a match, I always use full power ammo. I've even had guys comment, "wow, pretty hot ammo". Not really, just factory spec. Practice like you play.:whistling:

I would have no problem with that at all. I would just like it to be a level playing field for everyone. With power pistol I needed to be around 150 Pf just to run the gun. But I like PP. its fun to shoot and I have 8 pounds of it at home.

I would like to change that stupid 10 round rule. I know you are stuck with it but it makes no sense to me at all. I would never down load my carry gun in real life. If I wanted low capacity I would carry my lady smith or a 45. The only thing worst is when a revolver guy makes the course and limits everyone to 6 rounds. Yes it does happen here several times a year.

That 175gr should be moving a little faster, so maybe I'm getting around 780fps?
