[QUOTE="Fiftydriver, post: 780663, member: 10"] Roy, I am working on or will be working on some 270 bullets as well, the 150 gr Barnes tsx should show some promise in spite of being a flat base bullet. In spite of conventional wisdom, a flat base bullet will actually fly to 1000 yards and well beyond. Driven out of my 270 Allen Magnum it will clip along at a solid 3500-3600 fps depending on barrel length used. Its listed with a BC just shy of .5. With one of these tips, I would think it would crowd .6 BC pretty hard. A .6 BC bullet at 3550 fps is not to **** bad!!! The sierra 150 gr SPBT Gameking would also be a other great choice offering around .6 BC in finished tipped bullet but I am afraid that at the velocity potential of the 270 AM, it would pop like a big Blitzking on big game and really make a mess and not penetrate very well. The 140 gr Accubond will certainly be tested as well. IF Noslers new 150 gr LR accubond actually gets here and actually has a BC of .625, it will bring new life into the 270 AM but you can wish in one hand and crap in the other and see which fills up first. I think you know what I mean with that mental image!! [/QUOTE]
