If your shooting a stock SKS, stripper clips just work so well! I've bought two cases of the Czech stuff mainly for the stripper clips. Turns out the amo itself is decent too. Like others mentioned, I have lots of Chinese and Romainian ammo that I load up on strippers before every range visit. They make the SKS so much fun to shoot. Non stop action.
Those who toss them are crazy! If I couldn't afford cases of ammo on stripper clips or didn't have access to the Czech stuff, I'd still pay for them. In fact I bought some from SKSNub here on CGN when I bought my foirst SKS and case of Chinese ammo.
