I've seen 3 of these guns in 6.5 creedmore shoot now including this one. All shoot very good groups like this one. I don't think I'd hesitate on one of these if you are ok with reloading or running limited types of factory. The 6mms can be a bit more of a bugger. I'm with Jerry though. Looks like it just needs some tuning. I've found that seating depth is going to fix things the most. My 6XC needs to be jammed 20 thou to get the best results. 15 thou jam doesn't cut it. Doesn't take much to cause an issue.
Must be running the standard vld's and not the hybrids ?
