Bending over to pick up brass on a gravel-strewn range can be a genuine pain in the back.
And in the Cowboy Action/SASS game, we pick up our brass and shotgun shells after each person shoots because we all reload, use different calibers and appreciate getting our brass back.
The real problem is that, after you get your gunbelt and your shotgun belt on over your, um, belly...it's almost impossible to bend over at all.
(Ref only. Actual belly may appear larger....)
The general consensus is to employ an EZ reach tool and some sort of handled net or can.
I settled on a bait net (with 18" handle, extended to about 30") and a Harbor Freight EZ Reach grabber.
The wood handle on the bait net perfectly fits into a 1/2" PVC coupling fitting. This allows an easy extension with about 10"-12" of PVC pipe.
Bait nets can be found at Walmart or any decent Rod and Reel shop.

I've found the $10 one-piece (non-folding) Harbor Freight "EZ Reach & Grab Pickup And Reaching Tool" with rubber cups to work flawlessly, although I did put a drop of Super Glue on the mounting screws to make sure the rubber cups don't unscrew. Been using the original one for years now. The rubber cups are surprisingly nimble at picking up small cases, even amongst gravel.

I also use this pairing after regular target practice to salvage spent .380ACP, 9mm, .45ACP and whatever other casings are laying about, saving much wear and tear on my lower back.
