Good choice to sum this all up! Never did like 338 wm.Well, I traded the 338 off and sold the .270! I had been drooling over a CA Mesa in 300WM for two years. I haven't used a 300WM in many years, but have killed a solid 2 dozen nice animals with it, like the round a lot. When it all got down to the wire ( and sitting around here healing up from this new hip I just got!) I decided that "make do, won't do anymore"! I ordered the Mesa a few days ago and I will shoot the 150 TTSX as fast as I can get it to! ha Weatherproof, very handy, flat shooting ( I don't shoot at unwounded game past 375yds , just a personal whammy thing) and nice to look at. So thanks for all the advice guys, I still appreciate all the knowledge and stories!
