Just bought some ammo from WalMart today. I was told that they don't impose the 6 box limit anymore.
I bought 8 boxes of .308 ammo as follows;
4 boxes of Winchester Super-X 150 gr Power Point for $17.97/pack of 20
4 boxes of Federal Power-Shok 150 gr soft point for $13.97/pack of 20
I will mostly use the Federal for target practice and intend to buy a lot more of it later. Come to think of it...I should have bought all Federal since it is cheaper and based on the ballistic report, it actually performed better! Bought Winchester since it has better online reviews.
While there, I also saw some Weaver mounts and Grand slam steel rings and for less than $27 total, decided to give those a try. They look solid and good quality.
