20 degrees today, heavy atmosphere, DA -2500, Sealevel.
Loaded three, five-round loads:
Vv N550 all
Lapua brass, 2.005
CCR 250 primer
.337 bushing
B2O; 2.263 all loads, which is .020 off in my TRG
45.9gr
46.5gr
47.0gr
The two best groups were 45.9 and 47.0 at .283 and .313.
47.0 is *OVER max recommended load* for 175 SMK/VLD but I wanted to stretch my comfort zone with the cold temps, .020 off and light neck tension. I got only SLIGHT ejector shadow. No bolt-lift-effort.
The 46.5 shot an appalling 1.0" group so it will never be seen again. ;-]]
I left the chrony at home because I would be in shadow of the mountains all morning and it would be useless. I wanted accuracy before speed. Will get speed later.
Suppressed. .338P-1 (Recently discontinued)
Loved working with these bullets. Beautiful. Tips on the Tangent side of Hybrid. Slightly sleeker than the 185 Scenar.
See you at SHOT, Dave. :wink:
Buy them and ENJOY.
