Hey i noticed that you have and shoot quite a bit with the 6.5 wsm. I am getting one worked up as we speak. Benchmark 24" barrel 1:8 and a sako action with a McMillian stock. I have retumbo and VVN570 at hand. Which did you prefer for loads? I want to try and preserve barrel life so might back down a little if needed. I am not sure what powder is easier on throats?
