I'll put my 2 cents in here, simply because I have had both 7mag and several varients of 6.5 and would use either without hesitation. I have found the 6.5 PRC to be the most accurate round I have ever shot- might be due to the rifle- CZ 600 Alpha (ugly and heavy but amazingly accurate) After not having shot at all for months, I took it out and sighted it in, took half a dozen shots at 100, then proceeded to blow through all my remaining ammo hitting a 6" gong at 300yds without a miss. Every range session was the same. Again, might have just been the rifle, but I have never shot like that with anything else. As far as real world results go, the 6.5 in any variety seems to produce noticeably more emphatic kills than any I have had with the 7mag. Every deer shot with the 7mm has run off (sometimes100-150 yds!) or stumbled a bit before dropping, then kicked for 2-3+ minutes before expiring. Most of these have been heart shots, a few were lung- those usually being the runners. The 6.5 however, every deer has dropped in its tracks. I don't know if it's the longer bullets with higher S/D transfering energy more efficiently or what, but there is a clear difference. I once shot a buck with a light loaded .375 H&H head-on and it dropped him like he had been hit by lightening. Very quick but simply dropped straight down. My son shot a 160lb doe with the 6.5 head-on and it literally knocked her over backwards- full on end over somersault and didn't twitch again. I don't know what it is or how to explain it, but the 6.5's seem to out perform what their onpaper data shows. On a dozen deer for each of these, the results have always been the same. There is a reason the 6.5x55 has been the number 1 Scandinavian cartgridge for Moose and Reindeer for decades. If someone was to give me the choice to hunt with the same exact rifle in either a 6.5 variety or 7RM, I'd take the 6.5, and that is coming from someone who currently owns and likes a 7RM and doesn't have a 6.5 at this time! These are just my own personal observations, I'm sure there are others who will say the opposite is true for them. Everyone has their own opinion, but I certainly wouldn't say that 6.5's are overrated nor inferior to the 7mm varieties. None of either variety will make up for poor shooting, and any of them will ultimately result in the target's demise.
