[QUOTE="bettingpython, post: 1379189, member: 4307"] 1:9 twist rate will handle the XM193 55grain or the M855 62grain green tip ammo that sports world has available most of the time just fine. I have used both for the oil cap rifle match and at TDSA's carbine 1 class. If you plan on spending premium money for the expensive 69 thru 90 grain ammo for long range shooting in an AR then go for the 1:7 barrel twist rate. I am assuming USSA is using some steel targets for some of their stages in which case you can not shoot the 62 grain m855 since it has a steel penetrator and will punch holes in their targets, you'll likely be shooting 55grain lead core stuff for everything.
