Hey Mechanic:
A good "sealer" for your brass 410 cases is Lee Liquid Alox. It works fine, will hold your stuff in, and you get the extra benefit of lubing your bore every shot, slick deal. Just a dab will do, don't over do it. Best or only way is to warm it up, and seal your cases, and let it "dry" overnite if possible. It will harden up really good. Now, don't know if you can rough house throw them in your hunting bag, but I love the way they do for me. Also, the 444 cases work better for me than the 303 and any others I've tried. I really like the 444 cases for the 410, but I use the all brass magtech. You can buy oversize wads especially for 410 at CIRCLE FLY. Just Yahoo or Google for circle fly and they have lots of stuff and cheap too. Of course, there are lots more suppliers out there, just search.
Hope you got your stolen guns back and they have found the scum that done that to you.
I lost 3 fine ones in Shreveport several years ago, police said they would be traded on the streets for dope.
Best,
