I'm still working on my Steyr .243. Using 85 gr TSX, I'm getting about 1.2" 5-shot groups at 100 yds, and 3120 fps from a 20" barrel with 45.5 gr of H4350. I seat the bullet .050" off the lands.
I also shoot 62 gr VGs with this rifle. The last trip to the range I played with seating depth and saw that reducing the jump helped tighten the groups. I'm going to try that next with the TSX loads.
Any other suggestions?
