Tried 40 gr of H4831sc under a 100 grain Sierra Pro Hunter. Manual hints at 25-2600 fps. My goal is to save the barrel while getting productive trigger time. Accuracy compared to my hunting loads ( 44 grains) is unchanged and point of impact is dead on at 100. The heavier charge hit an inch and a half high. Groups ranged from 11/16s to 1 3/16 for 3 at 100.
There is slight shooting on the case shoulder, but there's a substantial increase in copper fouling. Seems strange...
My little Savage has been unfussy and eager to please. Am glad I took a chance on her!
