Reloading for the new .277 Fury from Sig

[Jim Kellogg]

These were just loads for velocity today, hence the large jumps in powder, chosen for their estimated pressure. Except for the 1st load, they're all over 65kpsi and right up to the limit, so don't be using load data from some guy on the internet(me) and not looking into everything first. But, to give an idea of what this round will do for anyone thinking about loading for it...
5 shot averages, 18in barrel, 2.950 COAL, 140gr BD-2, lever evolution. 29F OAT, because with this powder, it matters.
45.5gr - 2832
46.6gr - 2876
47.8gr - 2955
48.4gr - 2972fps

You did not list the powder, but your loads look very close to mine. I am using 145gr. Hornady ELD-X bullet. I took apart a factory load with 135gr. bullet and the powder was 48grs. No pressure signs at all. Powder looks like may be 4350. Oh yeah, factory load was 3030 out of a 20 inch barrel.
