I know how hard it is to find ammo for about anything right now. 223 especially. But i can find some ammo online right now to hold me over till all this paranoia dies down.
The question for me really is. Spending all day at the range. At 100 to 200 yards. Will a 26" heavy barrel make a difference in accuracy? And is paying more for the same scope with 4-12 power over 3-9 power worth it?
