I am planning to shoot the BullShop 460s w/100 gr of Triple 7 ffg to see if I get any accuracy degredation compared to using 70 grof powder. I am going to have some of the BullShop 620's for sabotloader!
Are you going to let him know they are 620's? 80 grains of T7 with them ought to bea pretty stiff whomp. Could surprise him, or ruin the range session for him if he not prepared for the recoil. Recoil will beclose todouble what he normally shoots.

May oughta prepare him for it.
Happy Hunting, Phil
