You will not regret it. I have the 30-378 and 6.5-300 in Accumark and really like the way both shoot. My 6.5 likes the 127 LRX the best in both Weatherby factory and my loads using US869. It handles the 140's ok but the group seems to open up a bit. I have never elk hunted with it since I have the 30-378 but would not be opposed to it. Good luck and like my Pop always said you can save gas in a VW but there is no substitute for cubic inches. Oh...and if you don't reload, I will buy all the 6.5-300 brass you want to sell me...LOL
