Would like to see that myself.

It'll have to perform to beat H-100V in the Roberts with 100's. Mine shoots the 100 TTSX at 3,266 into sub inch groups. That's pushing 25-06 data. And with no pressure signs. StaBALL should be more temp stable than H-100V.

48 gr H-100V with the 100 TTSX topped 3,300 fps, but at the cost of some accuracy. And still with no pressure signs.

47 gr seemed to be the magic load and the one I went with.

LA 700 with 24” Brux. Long action allows longer COAL and slightly more case capacity. But these are not compressed loads to begin with, so not an issue.
