I just saw Federal .40 180gr at Walmart for about $25, said it was on some kind of sale. I didn't get any but I'm thinking I should now, if I plan on carrying 180gr for self defense should I be shooting it at the range to be used to it or won't it make that much difference? This is just for target shooting in my gen 4 G23. How does it compare to the WWB I've been buying quality wise? Here's a post I found on Slickdeals about it: http://slickdeals.net/f/3831782-Federal-40cal-S-W-ammo-Walmart-100pack-25-96-9mm100pack-19-96 Wanna kill these ads? We can help!
