I picked up a Kelblys tactical SA for a deal and have an itch for a 25 short mag of some flavor. I have a 7 saum so I don’t want to run the risk of mixing up brass, it will be shot suppressed out of a 20’ barrel. Thinking the 25-300 wsm will have little more horsepower than a 25-6.5prc. Looking for a nice 800 yard and in deer rifle. Anyone have any experience with one? I’m thinking 270 wsm brass maybe better to start with than 300 wsm.. suggestions?
