I have a commercial Ross in .303 that shoots into two inches at 100 yards (open sights) with between 39gr and 40gr of H380, Woodleigh 215gr with an OAL of 3.15". This length is about as long as my magazine will comfortably handle and it seats the bullet at almost precisely case neck length. In the middle of this range of powder charges it chronographs at 2000fps give or take. Regards Tom.Information
