Winchester m70 coyote light 270WSM

FINALLY! After 3 months, great lengths and around 200 rounds (50 different loads) 4 different bullets, 2 different powders, numerous adjustments to the stock...I have achieved what I consider successful results. Ended up with 150 grn nosler accubond, 4831SC, Winchester brass and federal match primer. averaged 2900fps (20fps spread)at 3300ft elevation...
100 yrd zero, holding bottom right corner of square.

some times it pays to be stubborn... before this load the best was about 1.5" group... most were 3" this was the last test ladder before it was going in for a new barrel!

H4831 seems to be the powder for the 270 wsm at least mine likes it

I tried with magpro ... it was FAAAAAST but i could NOT get better than 1.75 inches... and but couldnt repeat that with the exact same load days later... temp sensitive??
