Re: 140 TSX or 150 Scirrocco
How are you testing these, John? Are you correcting for atmospheric conditions? Did you test the 150 Scirocco the same day the 150 XBT measured a .510? If so, you might wonder why the Swift measured so much higher even though it's advertised lower than Barnes advertises the XBT.
In any case, if you test the 140 TSX on the same day as the 150 Scirocco, I'll eat a box of them if they measure a BC 93% as high as the Swift as advertised. It will be much lower. Enough to increase wind drift substancially at long range.
