I know very little about this caliber, I am deciding whether or not to buy the kit in addition to my 5.56 and start to reload this caliber. Anyway I saw a box of 40 round count Winchester 123 gr fmj at WalMart for $21.00. I think for reloading this might be an okay deal? My friends who don't reload say to just go buy bulk (2000 rounds) of steel cased ammo somewhere which I think may be easier said than done. I reload for all of my handgun and hunting rifle calibers. I just don't know if I "need" another new caliber. If I did choose to I ended up on the 7.62 over the 6.5 and 6.8
