Re: 308 velocity's
If it makes you feel any better, I shot some Alliant Power Pro 2000MR through the chrony today. With a 1:12 twist, 175 Custom Comps shot 2808fps out of a 28" barrel. I was using 47.7 grains of powder. I found a good load at 975yds with a 2.5" dispersion using 48gr. I think I was in the 34MOA realm.
