Another thing, the 12FV feels very nose heavy to me with a plastic stock. Out in the field I would need a bipod to shoot long range on the ground but the plastic stock still worries me. You won't be shooting the 12 out the drivers window to often either at gophers. I have a 12 and a 112 both BVSS's pushing 13 pounds each, carry those around all day and your arm are an inch longer. Barrel life, during WWII the average barrel life on a M1 Garand shooting 147 grain steel jacket ammo was 10,000 rounds before they were considered worn out. And they used steel bore rods to clean the barrels, no wonder muzzles eroded.
