I just had to try Superformance in my #1 7x57. Decided to try the 150 Partition with it.
Started at 51 grains, and went up to 53 grains. 53 grains graphs 2850 and shot 1 moa.
No undue pressure signs, and no head expansion of the case. I'll take it!!
I had already established a good load with the 140 Accubond, but had not graphed it,
so today was the day [140 AB, WLR primer, 51 grains of Norma 204 in a Frontier case]
Chronograph says 2925 average for 3. All good.
Finally, I have a quantity of older Remington 150 Cor-Lokt bullets, originally designed
for the 7mm Rem Mag. Imagine my surprise to find a load of 4955 [49.5 gr] that shot a
ragged hole at 100 and 1.5" at 200 with this bullet. Graph says 2860 fps
Now to find something to shoot with one of these loads.
