264 WM test loads.

[264WM]

Just finished shooting some loads through the Crono.
160gr Woodleigh PPSN with 71gr H570 3 shot average 3083 fps.

130gr JLK VLD with 64gr H4831 3 shot average 3095 fps

130gr JLK VLD with 65gr H4831 3 shot average 3133 fps

130gr JLK VLD with 66gr H4831 3 shot average 3198 fps

130gr JLK VLD with 67gr H4831 3 shot average 3239 fps

Will take advice on better powder on the 130gr JLK VLD

I'd also try 7828 between 66-69, but retumbo is awesome between 63-66 grs and work your way up
Hope this helps

I am shooting 66.5 grs Retumbo with 130 Accubonds for 3350 fps from my 27 3/4" tube.

The book I am using is the old Hodgdon #20 which has some confusing information. It has the old H570 loads that give lower speeds on a lighter bullet with more powder. For instance it has 140gr speer with 72 grains giving 3187 fps then it has 129gr hornady with 73 grains at 3014 fps. The books H4831 load for the hornady 129gr is almost the same as what I shot the 130gr JLK with my crono at 18 feet they show 67gr at 3251 for the 129 gr at muzzle.
I am going to test the H570 with 72gr on the 130gr JLK.
