I have never been the type to be satisfied with one bullet for any of my rifles. With that said, for varmints I use the Sierra 75gr HP @ approx. 3500 fps. This bullet shoots one ragged hole in my Sendero. I can push it faster but what's the use? For larger stuff I use the 100gr Barnes Triple Shock. These, along with the 100gr Nosler Ballistic Tip, shoot 1/4" groups. I usually push these around 31-3200fps.
For powder I use IMR 4064 for the 75gr'rs and RL22 for the 100gr pills. Usually CCI BR2's, Rem 9.5 or even 9.5M's get the nod for primers.
What would be nice is if Swift would come out with a 100gr Scirroco in both .257 and .264. Those would rock the whitetail species. Later, Johnny K.
