My hunting load for the .25-06 is 55 grs. of H4831 and a 100 gr. Nosler Partition. It shoots 1 inch @ at 100 yds. or a little less. I use Remington LR Mag. Primers since I'm hunting in cold weather. You would probably want standard primers for warm weather. Or, I would cut the powder charge 1 grain with the Mag. primers in warm weather. The bullets are seated just off the rifling. The deer don't care for this load at all! The load is on the warm side.
As always, you mileage may vary!
Lock and Load!
