I ran the numbers with the .277 130TSX doing 3300, and the .284 140TSX doing 2950.
5" difference at 400 with a 200 yard zero, and 3" difference at 400 with a 300 yard zero. I was surprised at the BC of the 130 grain .277 TSX it is .413, impressive!
I have had some crappy luck with factory guns not shooting, and throw in that I am a lefty I have basically no selection of factory fodder in a lightweight/mountain rifle platform. When I go the semi-custom route I get exacly what I want, and It shoots! Flimsy stocks, 5 pound triggers and more than 1 MOA seem to be the norm with most factory guns under 1k.
I just assumed you hand load, but with the disclaimer of a factory round and a short action you cannot beat 3300 fps with a 130 grain pill.
