I've used a Dremel cut-off disk to cut Czech stripper clips in half. I then pinch the cut ends closed (or else the rounds will fall out) and paint the other end red so I can tell at a glance which end goes down!
I have used stripper clips for the SKS in CQB shooting (against the clock). I found it best to put 5 rounds on a 10 round strip, so a big handle was available for handling.[/QUO
+2 Works!!!!!! and no mods........so when the C.P are re elected and allow 10 round mags on semi autos, we can all use our original stripper clips !!!!!!!!!!!!!!
