Here is one from way out in Left Field:
I have Winchester load data that indicates they (at least once upon a time) loaded 150gr bullets on top of 748 powder in 303 British.
I was curious to here from the folks in the know how their mileage is/was with Winchester factory ammo.
I have been loading with BL-C2 with very good results, but I find myself with a fair chunk of 748 that could use a good home (it didn't fair well with my 7.5 MAS loads).
The table is open...
