Anyone have recommendations for a plinking load for the 585 Nyati ?

Hammer

650 gr woodleigh .577" black powder projectile in front of 140 gr of IMR 4350 (AR2209).

I have gone up to 155 gr of Imr4350. Awsome perfromance on thin skinned stuff

1200 grain cast lead bullet from NEI mold. Start out with 90 grains H4831. It goes "Whoooooooooooofffff....WHACK!" The 'whack' part is the bullet hitting the backstop. Recoil is about like a 45-70.
