Just wondering if anyone has found an accuracy load for the 168TMK? Heck, I guess any 168 accuracy load? I have some new 168TMK I'd like to pair up with the Barnes 168TTX. I've never loaded a 168 anything in a 300 Win Mag, always left them for the 308, 30-06 and 300WSM. I read of 73gr IMR 4350 as an accurate load, anyone have anything, I'd like any and all input guys! thanks.
300 Win Mag 168 TMK accuracy load anyone?

Little late posting but over the years (40!) 78 grs R22 has been real accurate for me in multiple 300 WM s. It ran 3175 FPS or so out of a 24” barrel. Many shy from R22 due to temp sensitivity but in my hunting rifles always did well. Also shot 74 grs of Imr4831 which was a tad slower but still quite accurate. (Sub-moa)
Work up to these loads as I found them NOT to be powder puffs!
Also, +1 to Scotty, regarding trying Noslers accuracy loads. They re generally very good. BTW, my loads were always with a 165 BT at around 3.5 oal. Typically .040-.070 off lands in rifles I had. Good luck!
