I went with H4350 with the 130 TSX in my .270 after testing alongside H4831sc and my favorite R22. The bullets are long enough that the other two were ending up with compressed loads and I also think the H4350's quicker burn rate may have helped bump up the bullets to fit the bore better. In any even the accuracy was much better, with the same velocities.

Let us know how they work for you.

Too close for irons, switching to scope...
