I agree with 65BR. I loaded some 130TTSX to 3100fps last fall and was banging my 400 yard gong with authority. Shot a nice buck at about 90 yards.... devastating. I don’t think my 270 has much if any advantage over it with my usual load of 130 hornady SP. But if I’m in open country with the 270 I’d probably load 140 AB with a much higher BC.
