Okay so I just took out my Precision 22 for the first time today and was really blown away how awesome it was. Anyhow long story short I do not shoot often, maybe a handful of times a year, but I like to buy stuff like I 3 gun every weekend. Anyway I would be shooting 100 to 200 yards max. I have both a 5.56 can and 30cal can so the real advantage would be that I already have mags and ammo for the 5.56 but should I just opt for the 6.5 or even the 308? I would be trying to shoot tight groups with this set up at those distances. It looks like there are a handful of 5.56 rifles available but I can't seem to find it on Rugers website so I wonder if they stopped making that version?
