One day last week I used a GRAF BRO. catalog and called the tech reps at the bullet and powder companies at the 800 numbers in the catalog.I asked for load data using their product in the 416 Rigby. One of them,who makes a 350 gr. 416 bullet,said" Just use any of the data you find for any 350 or 400 gr.bullet". I THINK it was the Speer rep,but I can't swear to it.

<br>Point is,I reckon they figure it aint no big deal.Maybe they are wrong.
