We don't yet know enough of your load data. e. g., powder, weigh, and OAL to see if your chamber is merely slow or you are using less than a max charge weight.
Having said, that, it is really difficult to get enough velocity with that bullet to make it an interesting long range item. The exception is the "Gee Whiz!" feeling one gets when connecting.
Have you considered a lighter bullet that will yield a flatter trajectory at the expense of some wind drift?
