Corbon`s new 180gr.JHP/1300fps load looks good and I can`t wait to get my replacement boxes (for the batch that was loaded too long OAL) to try them out. The bullet is a 180gr. Sierra,a decent bullet but I have to wonder if it`s ideal for the load? Most .40cal bullets are meant to be fired at .40S&W velocities. I`m wondering if say a 180gr. GoldDot,Starfire,XTP etc. might be better suited. Perhaps a 180gr. bullet that *underexpands* at .40S&W velocities would be just the thing at 1300fps.? Marcus
