Re: Chapuis Brousse 470 NE

Today, the Chapuis is finally mine! The paperwork is done, and I got rid of some hard earned cash.

Since the french girl liked the Norma 500gr FMJ rounds, I will try to duplicate them. The Norma cartridges is loaded with 114gr of Norma MRP-2 powder. As the MRP-2 is not being sold anymore, I will try a load of 106gr MRP. Quickload predicts similar barrel time and pressure curve as the factory cartridges, giving the same velocity of 650-655ms. The first cartridges has been made, and I really can't wait to burn som powder at the range this Saturday!
