Most popular light bullet seems to be around 350 gr in the LFN. Keep in mind that 350 gr is a heavy bullet in any smaller caliber and it WILL kill game cleanly as a heavier bullet if you were to run the same bullet to 1100 fps as you plan for the heavy bullet.
But I would love to sell you two molds, and to eliminate any confusion about your loads get a 350 gr WFN for the light loads, and a 420 gr LFN for your heavy loads. You'll never get your loaded ammo mixed up with the two completely different looking bullet noses. Also, the slow WFN's will hammer varmints and, with decent shot placement, any game up to deer.
If your bore is good you won't need gas checks for either bullet, as 1100 fps is a mild load for this gun.
