Cheap and reliable semi automatic rifle under 600? Looking from any calibur from 223, 7.62x39, .308?

I would definitely get a .22LR pistol. It's a range gun and you don't have money for ammo. Considering that you are planning on getting something for concealed carry later, I would look at some sort of trainer pistol.

You could get into something like a Smith and Wesson J frame in .22LR - but you said you had big hands and you aren't really planning on carrying this. So, instead I would take a look at something full size, like a CZ Kadet II. I have one, and it runs about any ammo I find for it, is quite accurate and runs exactly like a CZ 75.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
