Most of this is mine...

 

I don't know about the International Space Station but I ran around for three weeks with two pieces of 10mm brass lodged in the windshield wiper tray of my pickup after I was shooting at the local outdoor range.
It was only parked about 25' behind the firing line.

 

That is so close to the truth. Even with a 26# recoil spring.

i regularly loose about 30% of my brass. i think it burns up on reentry. My G20 only tossed full strentgh loads about15', while the P220 tosses 25-30", accompanied by 30% brass loss.I think I need to get a 48 or 50# recoil spring.

Lol, same with my P220 Hunter : (

Yeah, I need to notify the neighboring Zip Code when I'm shooting the Witness Longslide !

I lose more like 50% of my brass, between the distance it flies and the fact it's a hay field I shoot at, it's tough to recover much

Wonder if you set up one of those open tent shade structures nearby to capture the brass.  Might work for me as I set up on the prairie with a Caldwell shooters table.  Standing offhand would be another problem needing a bigger tent!

when I am going to shoot a bunch of 10mm, I set up one of those portable sun shades and hang screen on the right side and back. it stops the brass and really cuts the losses.

😀

I built this collapsible net. Set it on a tarp and stand by the net to shoot. It's easy to transport and stores nicely.

I took the idea of the Catch-All, Brass Catcher

.... and increased it to this:


I can set it up, on the Bench:


Or on a TriPod for standing, offhand shooting
It's been 99%+ affective

I have a flat bottom firing pin stop on the way, and 3 extra power mainsprings (aka hammer springs)to try, 25, 28, and 30 pounds. I'm hoping that this will slow down the slide enough to reduce the distance the gun throws the brass. Don't want to increase the recoil spring if I do not have to.

I have to chase down my 10's also , my brass catcher got a girl friend and that's the last I saw of him
