I can hit aa 8* paper plate at 200 yards iron sights with the mini-14. The 7.62x39 round isn't accurate past 150 yards,so I hear. The .223 is better in my opinion. High capcity mags are plentiful for the mini-14.Stay with PMI,that's the best after market mag for the mini-14. Reliable high capacity mags for the mini-30 are unknown to me except for the Thermold 30/45 round mags that seem to be very expensive and scarce. If you want a 7.62x39 get a SKS-D/Sporter model. This gun takes the AK mag. A way better value and a lower price tag of the mini-30. Plus the rugged 30rd AK mags are $10 a piece new.
