thanks, i've been trying to research it online but as always, cannot find a concrete answer or a reliable one. I know everyone has their own preference but just like the .223/5.56 is very popular and easy to come by, I would like to get a rifle in a larger caliber that may give me the same options.
7.62 x 39 would be the easiest I think off the shelf. It's been a couple weeks ago, but walmart in Anderson said they had 50,000 rounds of it in stock. Probaby gone now though.
I don't think I have ever seen the racks at Kmart without 243 Winchester, 270 Winchester or 30-06 Springfield. On my last trip there I know there were at least 10 boxes of each.
