I cannot decide between the .300 winchester magnum and the .308 for hunting. I'm in texas (fairly small deer) and I will be hunting those deer at up to 750 yards (not always that is the farthest possible shot) and elk at farthest ranges of 550 yards. Maybe the occasional moose inside 400 yards. .300 winchester magnum pros and cons I know of. pros: 1. It retains a fair amount of energy at far distances 2. Semi wide range of bullet types and sizes cons: 1. Recoil makes it a hard gun to practice with and I want to be able to get very good with my gun 2. I hear it eats up barrels and I am getting a custom rifle with a nice barrel and do not want to worry about every missing a shot because the barrel has been worn down. .308 pros and cons I know of pros: 1. Immense variety and sizes of bullets and has better over the counter ammo. 2. Lower recoil than the .300 so I can practice more and get much better at it and make much more accurate shots 3. has a fairly flat trajectory (better than the 300 win mag) cons: 1. This is this is the only one that I know of but it is worth three bad points at least. I do not know if the .308 will kill an elk at 550 yards. I just can't decide which caliber to go with. Thanks for the help.
