One advantage of the very low-cost but powerful MN rifles also is the ammo which so far has not really gone up much, if buying in bulk.
The Ammo section at 'Gunbroker' last night displayed lots of x54R ammo with current bids (or "buy now"), which are equal or less than the lowest wholesalers-with shipping a constant cost.
One lowest-price seller in Stillwater, OK published a photo of the warehouse where many crates of the ammo are heaped up in nice, neat stacks.
And for short-range, although 7.62x39 ammo has gone up, it is much more widely used than M-1 Carbine ammo,
i.e. by many millions of SKS, AKs, Mini 30s.
