I had a Browning xbolt 270wsm and ran federal fusions 140 or 150s... I can remember which. They were hot! 3300 fps plus. I could never duplicate those velocities handloading.View attachment 1286974So here are 2 cases from my nephews 270 WSM Factory Federal loads shooting CA. loads. It was almost impossible to work the bolt after a round was fired. What do you think? A little hot? Sorry for the fuzzy picture I just couldn't get the camera to focus.
