re: First hunting rifle. Stainless barrel? And caliber question.

I have a custom 270 made on a Remington 700 action that's 416r stainless. I had them cerakote all the metal parts.. they gun smith that built my rifle shoots 800 yard matches and all of his bench guns are stainless. I highly recommend the cerakote. I hunt on the ground and my gun gets wet muddy etc. A quick wipe down and it's good to go .
