www.gunsnammo.com has some for $59 for 500 rnds.
Has anyone tried this stuff in a Walther PPK(or anything else for that matter) and did it cycle OK and have reasonable accuracy.
Oops, didn't see the .380
I tried it in my .32 and it keyholed @ 15'
I pulled a bullet and shoved it right down the barrel without it engraving the rifling at all.
That doesn't mean it will be that way for you.
The surplus FN worked great, OTOH.
