.308 win - Accuracy Powder

[Willoughby]

my fouler group was .5moa with varget -before load devlopment
why ?
because is just happened to be the correct amount of powder
to have the bullet exit the barrel
while the vibrations were at the the chamber end of the barrel
ANY powder will produce good accuracy
if
if
if
you find the right amount for your barrel & bullet
some powders will be consistant regardless of ambient temperature
Varget is one of the latter
mag primers are actulay called for in some 243 & 308 load data
over pressure is readily seen in the primary overpressure indicator -the primer
after each upward increment in load development the primer should be inspected for pressure signs
