I shoot a 243 and 7 rem mag with 95 and 180 grain bullets. I have a 270 win BDL I shoot 130's out of. I have a 22-250 and 223. I am looking at something new, I just don't know what yet. I am thinking another magnum long range rig. I have always wanted a 300 win with 215's but is kind of close balliatically to my 7 except a little more energy. 300 RUM sounds entertaining but when getting to that size it starts to get more spend to shoot which I am not terribly opposed to. A couple questions to help with my decision. Also if you have any personal suggestions of preferences or thought processes on the topic go ahead and let me know what you are thinking. 1) This most likely will be a factory rig, so how much velocity can I expect to get out of 215 grain Berger's in a 26" barrel on a 300 win mag and an RUM? 2) How much velocity will I expect to see out of 230's? Any other caliber suggestions are cool. I am leaning towards more horsepower rather than less. Just because I guess.
