I was going to build a 7stw, or 300 win, but am setting my sights on a 300 rum now, because a friend who has been loading for quite a few years, has told me that he can work up 2 loads, one for long range, hard hitting, flat trajectory for killing Elk out to about 600yds, and one tamed down for my bush hunting that will shoulder bite me like a 300win. Which will be 75% of my hunting, but both can and will happen in the same day at times, when we hunt out to our tree stands which gives us clear views from very low yardages, out to over 700yds. My question,,, is the 2 load idea a reasonable idea? Poking fun at my vast knowledge is OK too. I have a tough chin.
