Here are my thoughts on 6.5 Creedmoor based my experience. So I have killed a couple under 150 yds and had satisfactory results. With that said, I also killed a doe at 648 yards. I was fortunate and lucky I suppose to have made a near perfect shot and the doe only went about 5 yards. After dressing the deer, my opinion is that the wound channel was pretty small and would not be very forgiving for a marginal shot, especially on a larger deer. All were taken with 143 ELD-X. So, I don't think there is a certain range where the 6.5 Creedmoor is suddenly no good, but I do think at longer distances it can really be unforgiving for marginal shot placement. I am more of a 7mm Rem Mag guy for an all around deer and elk.
Good discussion folks.
recoil management has to the CM
Long range precision also to the CM
Effective killing at 400 to 600 and beyond Has to go the 308 IMO due to a bigger bullet 165-178 and bigger in custom barrels.
With that said, and I have dropped dozens of game with both, bullet choice is critical. I found the Barnes LRX do fantastic on 100-400 in both calibers.
the Noslers and some other lead core bonded bullets do better on thin skinned game than than the solids in the 6.5 beyond the 400 mark.
only exception is pigs but that's because I always go for the high neck or ear hole shot. Pretty much everything drops them. Whitetail, axis, blackbuck, fallow all seem to drop better past 400 with lead but again that's just my experience
so with all that said I recommend trying other bullets for the 6.5CM get some practice on pigs and meat hunts. My favorite is the neck shot due to the disruption of the nervous system.
Last note, "big bullets make big holes" while the 6.5 is more controllable especially in lighter rifles and lighter shooters, 308/7.62 is a bigger bullet.
For what my 2cents is with gents.
