25x47 Lapua load data

[bbyars]

Shot to 1000 today and gained a little more speed. Some where between .335 and .35 G7 is matching on the 134 ELDM at 2700 fps, gonna confirm tomorrow. Still havent measured the jump but im seating right at 2.8'' COAL with a .135 freebore. After this match ill probably play with some varget and see if i can boost the speed a little, H4350 seems a little slow in this barrel.

Appreciate this. Look forward to what you find out. Seems like a few guys are running above hornady published bc

Upped the axial form factor on 4dof to get to match. Think that came out to .9
