I currently have a built Tikka 270wsm shooting 165gr bullets. This is my go to lr rifle for any animal i hunt. It covers all my lr hunting situation in my opinion. However, i would like to build another lr from my sa savage. Needs to work in sa mag fed. Not interested in a light varmint round or real heavy hitters. Looking at a .260 or 6.5x47. I would like something that does what my 270wsm doesn't, but I'm finding that hard to do. I want a purpose built caliber, hunting performance is the number one goal, elk, deer, antelope. Suggestions?
