I was looking in the Lyman 49th edition and it lists the max load for IMR 4350 at 81 grains for a velocity of 2629 for a Swift A Frame 375 H&H.

It seemed quite high so I called IMR and they said the max load should be 76.5 - does anyone have any suggestions - I am going to pull the bullets. Based on Lyman book I did the starting load at 77 - I am wondering whether that is even safe.

I am shooting a Winchester Model 70 that was made a few years ago.

The A frame is very accurate and I am trying to duplicate the Remington Factory Loads that I have had for a few years. Any help would be greatly appreciated.
