Cabelas doesn’t even list 5.56 or 7.62x51 now. Nor the powder, brass, or bullets to reload those calibers.
At least, not here in the Rogers, MN store...
I was in a Cabela’s on saturday, and they actually had a bin of 30rd AR-15 mags (limit 2).
Also, they had 7.62X39 in plenty (steel case),
but no a single cartridge of .22LR.
You can either cast or swage bullets. Casting is pretty cheap, swaging requires heavy press and dies. At this point is not normally cost effective for an individual.
There are a lot of manufacturing facilities in Texas who could easily make jacketed bullets.
