First impression.. wow. and damn. gonna need a recoil pad
Rem 5r .308 just under 500rnds thru it. Barrel must just be comming in or something as All loads increased velocity throughout the test.
All loads shot round robbin sometimes in reverse order.
temp 85-90* wind 15-18mph 90-160* near as I could tell as I was next to a tree line with wind from the tree line.
Only measured verticle dispersion because of wind.
my pet load has been 42.5 Varget with 168 amax or 175 SMK, great shooters but not enough for 1000yd f-class hence the test for more velocity with 178gn bullit.
All loads shot @ 200yd with 178 amax .020 off lands.
Winchester once fired brass.
BR2 primers
I wont detail the Varget stuff other than say with 178 amax today best vert group was .739" with 44gn Varget @ 2602fps which is just good enough for 1000.
ES @ 35 which sucks.
Now for the Alliant. FPS average of 4-5 rounds
46.5gn 2623fps es13 3rd best vert of .731"
47.0gn 2628fps es 20
47.5gn 2680fps es 21 Best group .369" verticle
48.0 gn 2721fps es10
48.5gn 2744fps es21 2nd best @ .725"
49.0 2779fps es. alot 1 shot @ 2811fps!
First shot with 46.5 flatend the primer a bit and I thought this is going to be a short test. But it did not get any worse. Most primers were fairly flat and occational very light ejecter marks but it never got any worse thru the test.
Overall I am impressed. more speed, tighter es and better groups than my varget loads.
