Re: 140 TSX or 150 Scirrocco
Gene I shoot both the 140 and 160 TSX in my 7MM STW Remington Sendero with the 140gr I am at 3613 fps and with the 160gr 3276 fps and there are no signs of pressure from either load but every rifle is different. I would say with the 140gr you should be able to get around the 3500 fps mark pretty easy if you have a 26 inch barrel. Dont worry about a Barnes X with close shots I dont think there is a cartridge that can push them fast enough to come apart they are probably the tuffest bullet I have seen and they take game down quick if you do your part.
Fast, Flat, and Accurate
