I,too. have a LW Super Grade.
It groups 5 shots well under an inch with145 LRX and StaBALL 6.5 with 210 primers. Seating depth is critical with 3.10" being ideal. 2900 fps was easily achievable with 50.5 grains.
Still experimenting with the 150 grain Sierra. 2850 should be achievable with StaBALL. 3.00" OL seems best so far.
With other powders I would not exceed 2800 with the 145 LEX or 2750 with the 150 grain as the Hodgdon manual shows a 100 fps advantage for StaBALL.
Cheers,
Walt
