Hello, right now the issue is none of the clips won't line up with the feed guide on the reciever. The clips do however hold rounds fine.With Mosin strippers it sometimes helps to stagger the cartridge rims as you place them in the clip. Kinda like an Enfield clip.
With SKS strippers that were tough to push through I'd take a spent cartridge and CLP the clip and run the spent cartridge back and forth till it smoothed out.
