I've used steel cased ammo, in both my 223 and my SKS=7.62x39, and My Mosin's with some decent results and the Mosins giving me the better of them. It's not the best, most precise consistant ammo, and I don't believe it ever claimed to be. Brass is better, just all around.
Still I would order some to at least try out and just plink with. Like marylandeer said if nothing else helping practice form and have fun with. I've tried the Silver/Brown Bear and Wolf ammo and don't see much difference. Many are against steel cased ammo and won't touch the stuff, but I like to shoot. If my ammo doesn't hurt my rifle, then I'll shoot it.
Sense you guys are using a pump and auto louder I guess I should mention that there has been some debate about steel cased ammo wearing the inside of the chamber out. Like in the case of an SKS or AK. But I can't speak from experiance about that in particular. All I can say is that I have had a lot of fun with steel cased ammo for only pennys and nickels a shot.
Hunting with it? I suppose you could use it in a spot, but I would opt for better ammo dedicated for hunting, and the -06 has a TON of great factory loads at a fair price. Federal, Hornady, Winchester, Remington, take your pick.
