My starting load grouped at 2" as the powder charged increased the group spread to 6" at max load. With the heavey bullets start load was 3" and increased to about 7" At max load.
Cal 25 06, bullets sierra 100gr, hornady 117gr, powder H4350 barrel 22". bullets seated 3thou off.
Is there anything obvious that might help with this combination ??
Thought powder might soot lighter bullet. ??
