RE: Loads for 7 mm R.M. and 140 gr TSX
I run H1000 w/ 140TTSX . . . . found it to be a bit more consistant than 22 when the temps dropped. I shot 22 for a while but when I would go from 70 to 20 degrees I would lose like 150fps and groups would go from .75" to 1.5" with a shifted POI.
But maybe you'll have better luck than I did
