The size of this media won't get stuck in the flash holes. You'll be surprised how shiny the cases come out. Could they be shinier? (not sure if that's a word) Probably. But I go to a range to shoot quality ammo, not participate in a shiny case contest.
dont waste your $ on the pet store stuff, you're paying more because it says "pet" on it.
go to Harbor freight, use the 25% off coupon to buy a 25 lb box for $23. (less the coupon of course)

you'll have enough media for dry tumbling for years and years and years.
as noted the Nu Finish is a nice additive for polishing, and get the cheapest dryer sheets you can find and throw one of those into eveyr batch for dust collection. It'll help your media last longer and keep your brass from coming out dusty.
ive been told that used dryer sheets work well too, so maybe try them too.
i will say, once i went wet with stainless i've never looked back. although i do still use my vibratory tumbler with walnut for rough cleaning and lube removal. I dont like putting dirty (picked up off the ground) brass through my case feeder so 10 mins in walnut gets the grit off, likewise for case lube removal after sizing. I still do my main cleaning with stainless pins, lemi shine & dawn though as it saves me from cleaning the primer pockets and you cant beat the results for the time invested.
the frankford arsenal kit goes on sale for around $129 a few times a year and is regularly on sale for $150 or so.
