In the .40sw does 5.6 grains of Win 231 fill the case and make it a near compression load with xtp 155's?

WELCOME TO THR!!!

I have used a 6.0 gr load of 231 in a WW case with a 155 gr XTP, and that is not a compressed load.

Good Shooting

THANKS... THANKS --- I nearly made a real bad mistake. Something just didn't look right when I loaded a sample 15 rounds. Cases were way to full for "common sense". I posted this question and then began some double checking... I had set the scale wrong. I destroyed these cartridges... and did another ten. Better to loose a few reloads than mess up a gun.

I triple checked the scale against known weights this time. I want to start with 5.6 grains. Now a "visual" (I use a good light) show cases are "about" half full.

I am not an expert (I follow the books carefully) and this web site is new to me BUT I can't thank those behind this enough.

High-pockets88: If you are not yet aware of it, there is a Hodgdon (i.e., the owners now of Winchester powders) data reloading center. You can easily download the data for .40 S&W and 231 powder.

I just checked it, and I see that a 155 XTP over 231 in a .40 S&W case has a MAX load of 6.0 gr. So, your start point of 5.6 gr. is just about optimal. Hodgdon shows that MAX at a LOA of 1.125"--so, also check your LOAs; .40 S&W is touchy about pressure.

Here (http://data.hodgdon.com/main_menu.asp) is the link to the Hodgdon Data portal, if you don't have it yet.

added on edit: when you say you 'destroyed those cartridges,' I presume you mean you took them apart using a bullet-puller inertial hammer. If you don't have one of those yet, get one.

thanks jfh -- the web site was what I needed. I do need to get an "inertia puller" - will look one up from MidWay on my next order...
