I have historically shot 140 accubonds in my .280 I played with some 140gr TTSX this past summer and they shot very well. I shot one deer at about 75 yards or so and was impressed. We do shoot the 80gr .243 in the rifles for the kids and no complaints there either. I have played around with the GMX, they give similar results on animals but haven’t given me quite the accuracy as the TTSX. I do get more rounds down the pipe between cleanings with the GMX’s. But then again every barrel will vary.
