I have killed more deer with theHornaday 300 gr. XTP in the last eight years.
I recently upgraded my NEF Sidekick with a new breech plug and now shoot 85 grs of BH209 and the 300 gr XTP and am still getting great groups. When you got a good setup, you need to stay with what is proven.
All ya gotta do is look in my deep freezer at all the meat in it.
