Is it true ?
Sir Larry has suggested it should be verified by home testing.
I will get around to it, dissect a round and chronograph

Powder charge appearance and weight and corrected MV for a barrel of what length ?

I have yet to shoot that Norma .458 WinMag ammo with 500-gr Swift A-Frame.
Maybe I will get to it when checking the deer rifle zero this week, same rifle,
but the deer bullet is the 404-gr Shock Hammer.
