Finally got a chronograph and took it out yesterday.
Temp: 57
Wind: Swirling
Humidty: 39%
Elevation: 600ft
I did a full 50rd load workup (5 rounds each per charge) : Hodgdon lists 25.5-28.5 for 8208XBR but i always skip the first charge and go a little over max checking for pressure signs along the way. Standard disclaimer, don't do what some random guy on the internet does! So 26.1 - 28.8, and I found 2 accuracy nodes
Powder: 8208 xbr 27.6
Primer: rem 6 1/2
Brass: lapua (1 fire formed, the rest new same lot)
Bullet: 123gr Nosler CC
COAL: Mag length
Barrel length: 20in
make: Shilen SS
FPS AVG: 2462
Powder: 8208 xbr 28.5
Primer: rem 6 1/2
Brass: lapua (1 fire formed, the rest new same lot)
Bullet: 123gr Nosler CC
COAL: Mag length
Barrel length: 20in
make: Shilen SS
FPS AVG: 2591
(For those of you not doing the math at home, that's 1200 FPS at 1k yards)
