I have had my .25-06 shoot very good groups with 87 gr HP bullets, but have settled on the 100 gr Nosler BT for a hunting bullet.
The most consistent accurate load in my rifle uses IMR 4350 to push the bullet over my chronograph at just over 3,100 fps with a small shot-to-shot variation that is somewhere around 11 - 15 fps for 5 shot strings. Group size with this load is a bit under .75". Hotter loads have produced higher SDs and more inconsistent groups for me.
