Understand the possible implications of this pretty popular in caliber very unpopular in amount of ammo on hand per owner of said caliber.
Add the potential for this situation odd ball hell 30/30 is one of the most common rounds in america I have a set of dies for em. Dont own one but i have dies have 30-06 dies too.
And place yourself in a sweet spot for horse trading if you pick up every fired shell you come across and just sit on them till needed...
My thoughts exactly when i picked up my reloading gear used (paid $150 or 200) its came with several dies 30/30, 30-06, 9mm, .308, 7 mag, and .222 rem, I could have sold all the stuff i dont need. But 30/30 (last I read) was the most prominant cal. in the US, followed by the 30-06 may be switched now. But none the less I kept both dies. 9mm and .308 are obvious, 7 mag is bit in this area as a hunting round so it works out great, and .222 rem was a very popular target round before the .223 rem came about. So to you reloading guys think of trade value in picking up dies that you dont shoot, brass is cheap right now. Pick up some good, small rifle, large rifle, small pistol and large pistol primers and a few pounds of general rifle and pistol powder and you are sitting on a gold mine!!! Not to mention guy down may not have a .223 7.62x39, .308 but i bet he has a deer rifle in 30/30 or 30-06. Also just a little tip 7mm-08 can be sized to .308 check your put up brass boys!! I pick up all the brass when i hit the range, I take a 5 gallon bucket and actually empty the trash cans. In SHTF brass will be a valuable commidity so hold on to what you can (and if you hard up from cash you can always scrap it)!
P.S. Spell check isnt working so oh fucking well
