Wait times in IL for FOID cards are variable, but you should see it in a couple weeks.
Currently, there are no round limits on magazines in IL, so no worries there. Your biggest problem these days may be finding ammo to shoot.
Get you FOID, get your guns, and go shoot.
" Of every One-Hundred men, Ten shouldn't even be there, Eighty are nothing but targets, Nine are real fighters... We are lucky to have them...They make the battle. Ah, but the One, One of them is a Warrior... and He will bring the others back."
