Greydog, those results are not skewed. they were taken directly from Hornady's website. please reference it for yourself. the 7mm-08 load is hot and the 308 load isn't? both are factory loaded ammo using the same type of bullets. how do you know whether one is hot and one isn't?
I'm only interested in comparisons I can verify. I don't do comparisons based on what it says on Hornady's website or in someone's program. I only go by what I see over the chronograph and in the field. I know it is pretty tough to break 2900 with a 140 in a 7mm/08 because that has been my experience in over thirty years of shooting them. At the same time, I know it isn't too tough to break 2900 with 155's out of a 308.
Having said this, there are some combinations with which the 7mm-08 is a real overachiever. I am always amazed that it can push heavy bullets as fast as it does.
In truth the 308, with a good 155 shoots slightly flatter out to 500 meters and at 1000 it's pretty well a wash if the 7-08 is shooting a 150. With 168s, the 7mm-08 enjoys a much better BC but the higher velocity the 308 can achieve almost makes up for it and the 1 moa difference in drop is insignificant at 1000yd.
In the end, the choice of one over the other is as much a matter of perception as reality. I like the 7mm-08 and I like the 7x57. In fact, I have another 7mm barrel (a Benchmark HV taper) I'm fitting to my open "F" class gun for this year as we speak (write). Maybe this will be the one that finally beats the 308. It will be the first. GD
