Have not used either the bullet or the caliber, but have used the Barnes 110 gr. TTSX (b.c 0.377) in my LH Tikka T3 Lite in .270 Win. Loaded to 3400 fps using Re17, it is fast and flat shooting to 600 yds. (longest distance at which I have used it, checking zero during F-Class). I killed a mule deer buck with this load, held for 300 yds. and hit right where I aimed, though deer was actually at 250. Deer took a leap and turned a sumersault and that was that.
I have recently started using H4350. Accuracy is better, but I am not able to get quite to 3400 with safe pressure. That is ok, much prefer consistent accuracy.
Hope that helps.
