I shoot the R14 matches, the Ant Hill matches in Supply NC, right on the coast about 1hr50min from Bragg and the Sir Walter Gun Club matches in Creedmoor, also about 1hr50min from Bragg and I just started shooting the IDPA matches in Oxford, right at 2 hrs from Bragg...feel free to post or pm any questions about any one of these....
The schedule of all USPSA matches in NC by weekend (for example, Range 14 is always the second Sat of the month) and some of the IDPA matches can be found here:
