I am having a gun built and having a hard time trying to choose 6mmBR or 6.5cm, I have not competed and probably will not for a while at least. I really just enjoy load development and shooting small holes at my house too around 300 yards. My question is, if I go with the 6BR and decide to compete, how big of a disadvantage do you think I would be at in a match shooting past 700 yards? I’ve read the stats on wind drift etc but wanted first hand experience other than charts comparing the drifts. I chose these two calibers due to ease of case prep and barrel life. So not interested really in the 6cm or a 6BR wildcat.
