I know it has it's own forum... but I am loking for lighter load data for practice and accuracy.

So many want to push the chronogragh to it's limit..
I am looking for tip and loads to go easy on the brass and the pistol.

After 40 years of handloading, this little bugger has some new challenges!

Just commenting to get the thread moving. I don't have one, but would like to. I'd like to have one and hug it, love it, and squeeze it down to .17!

I vote it the "Cutest Cartridge".

i don't have one either [i use the brass to make 30 cal bullets though]
i recall handloader done an article when the round first appeared, it was pretty detailed so it wasn't recently.

From Wiki:

http://en.wikipedia.org/wiki/FN_5.7%C3%9728mm

quote:

FN's 5.7×28mm cartridge cases are covered with a special polymer coating for easier extraction with the PS90 carbine due to the high chamber pressures and lack of case tapering.[32] In addition, this coating ensures proper feeding and function in the magazines.[32]

This tells me the PS90 is a blow back and requires case lubrication, here probably a teflon coating, to properly function.

How do you get the lube back on after reloading?

Don't use a POS90.
