Phil, Congratulation on a beautiful Rifle! Well done sir!

I am enclosing an email address of a double rifle shooter/reloader 450#2 NE. He has extensive experience loading for the 450/400 3 inch using lighter bullets and maintaining regulation! His email addy is NE450No2@aol.com Please contact him and tell him I sent you! (He Killed a coyote with a 9.3X74R scope double Chapuis in March. Hit the animal with both barrels at a witnessed and lasered range of 270 yards.)

There is also another source of bullets. Hawk Bullets .

They make the .411 in 3 differant jacket thicknesses. Hawks are much softer than Woodleighs and require a bit less powder to achieve the same velocity.

Let me know if I can be of assistance!
