Wow. Some body didn't get their coffee this morning. Ok so here we go. I'll run some numbers for you. 800 yards in a 10 mph wind.
115 berger at 3200. 16.5 moa of come up, 5.4 moa windage, velocity 1787, energy 815.
140 eld-match at 2850. 18.8 moa of come up, 4.5 moa of drift, 1824 fps 1034 ftlbs.
This was ran at 1000 ft elevation. I ran 2850 for the 6.5 because that's what manuals list it at and that's actually slower than my loads but for arguements sake I ran 2850. As you can see, the 257 does not "spank" a 6.5 at 800 yards. I don't know what else to tell you.
I ran the very best 257 bullet available. So to make it fair, i would have to run the very best 6.5mm bullet available which is the 147 eld-maych and the 150 smk. Sierra lists their 150 at 2800 with a 24in barrel. So I'll run that number for you with a .710 bc.
18.9 moa come up, 4.1 moa come up, 1866 fps, 1160 ftlbs of energy.
You can THINK I'm a supporter if you'd like. I stay 100% as completely honest as I can. I just proved my arguement what have you done other than just spew off at the mouth? It's clear your on a mission against the 6.5 creed because of your hate for the supporters or whatever it may be.
