The FNGC that I have been using are a LBT style bullet that Cabelas sells. I really like the way they shoot. I will have to check and see what other weights they have them in. I think as DM says, the lighter bullets would be more pleasant to shoot and in a hard cast bullet the 300 grain is probably more than needed for deer and Black Bear. For elk and moose the 300 would be fine. I shot one elk with the 300 grain XTP. He went down like a bag of rocks.
