I have found Barnes 168gr TSX to be the best bullet for my 300 Win Mag. I use 78.0 gr of RL-22, WLRM and seat them at .040 off the lands. Accuracy is sub 3/4" and muzzle velocity is 3140 with a 26' Lilja. I can go a little faster, but sacrifice some accuracy. I have found the finicky thing about all Barnes bullets is the seating distance. Once you find your "sweet spot" there, you've got the best round there is for terminal effect. I'm shooting the 168gr TSX in 300 Win Mag and 300 WSM (very lightweight) and the 210 TSX in 338 Win Mag. I have friends who are experimenting with the new RL-17 in 300 WIN Mag and 300 WSM with significant increase in velocity. I'll be trying the RL-17 as my next project.

Interesting. I've got a 26" Lilja too, but evidently I have a tight chamber. 78 grs of RL-22 gave me 3350+ fps with the 168 TSX. It also gave me hard bolt lift, so I backed it down to 74.5 grs which still gives me close to 3200 fps. I've found the same thing with other powders too. I have to back off 3 or 4 grains from most published max loads with everything.

I was tinkering with some loads for 180 and 165 grain tsx. I got 3120 with 77 grains of Rl22 with the 165 and 3000 with 75 grains of RL22 with the 180. Both are about 2 grains over Barnes data and slightly less than Hornady data. Neither produced sticky bolt, flattened primers, or expanded case bases in my M70. I haven't gone any higher than that so far. I didn't shoot for accuracy.
