The 270 SS should get around 3300 with the 140 Berger classics and rl26 in a 26" Bbl. My 270 WSM shoots them them at 3350fps seated deep to fit in the mag. I let my buddy use it when we went Audad hunting. He hit a big bodied ram quartering to us, head to the left. He shot it standing with his bi pod on a boulder at 225 yards. Hit the ram right in the shoulder and the bullet blew up in the vitals, destroyed them. He took it like nothing happened and ran 20 yards in a dry creek bed and dropped. The the 140 Bergers blow up at closer ranges sometimes but it still drops deer sized game. At medium and long range it performs well. Overall I like hunting medium size game with it. Next bullet I will be trying is the 165 matrix. On another Audad hunt my hunting partner shot one with a 300 Norma with a 230 Berger at 450 yards and it was DRT. They are tough animals.
