Loaded for same rifle for a number of years that a mate owned. He took most of his best animals with the 140gr BT, 52gr W760 (H414) & Federal 215M magnum primer. 139gr Hornady didn't shoot as good as the BT's in that rifle. I have a BSA Royal running 50gr behind a Speer 145gr, mild to shoot. As always, approach this load weight with caution, IIRC it had a bloody long throat which is common.
