LAX 180gr FMJ Plated (IC 5/17/14) Pull-down

[4949shooter]

   I put another thread together with everything in the reloading section (maybe sticky?). Everything to date I have also forwarded to LAX. If they just pick the PPU out, I think it will be fine ammo for shooting.

Thanks. What is the price on the LAX?

  It's $110 for 250: http://www.laxammo.com/ammunition/handgun-reloads/reloaded-10mm-180gr.-250rds-w--ammo-can/22-85

Just what did it take to fix the PPU brass to actually hold the bullets?

Well I repulled the reloaded rounds I put back together.  I resized and deprimed the two of the PPU cases and here are the results as measured...





Next I did a dirty annealing process on my gas stove, heated the cases till the started to discolor, could have probably heated a little more, water quenched, then resized again with the RCBS sizer and here are the results as measured...





As you can see they did close up and hold their size better.  I was seeing 0.3970" and 0.3975" on other multi fired brass with just resizing.

I think these were hard/brittle and possibly on the thin side...0.0100" thick at the mouth.  Their manufacturing process and or alloy are suspect in my opinion.  Reloading also work hardens the brass even more.
The annealing process is used to soften the alloy to make in more malleable.

9x25

I don't think so but if I were to rework them to 9x25 the neck could crack or split, loading them to the level I load at would be taking too much risk even in a fully supported chamber.   I have one PPU case that is not annealed and could test the results of working it into the 9x25Dillon cartridge...

Making Changes to the LAX powder being used for the following reasons...

Originally I looked at this powder and it looked like Power Pistol (these would typically run 1200 to 1230 fps), after further research and studying the why the velocity numbers were so low, IMR4756 powder fits much better for the loading data and yield.
Hodgdon shows 180 gr Sierra JHC 7.6 grains at 1155 fps 34,400 psi.
