All I ever shot in my former 7mm RUM was the 140 TTSx. I used both 7828 and Retumbo (I got more speed out of it too) . In fact, in it and the 300 RUM, I found Retumbo to be the best for both accuracy and speed. I live right down the road from Barnes for the past 26yrs, so I live in Barnes Country, ha. But I am going to try the Hammer bullets as soon as Steve gets the 358 worked out. I am using a 358 Norma mag and his bullet will come in at 220gr. I have shot elk and elk sized Plains game with magnums and lightweight Barnes. I like the flat trajectory/speed/less recoil, but the bigger caliber makes a bigger hole...that's just a quirk I have, as I used a 300 winmags and 180 XBT for years with great results on the same sized game. Here in Utah the 7mms are very popular ( I like the 280 the best, but I don't shoot that far, not near as far as most on this website do or aspire to.) Good luck, and I agree, our new president will be looking into the trade deal. Goodness, I never understood why Canadians can't get US products like that...oh well...
