Results time.
All loads are 4198 and all velocities average. No test for accuracy.
a. 20 grains: 975fps
b. 19 grains: 925fps
c. 18 grains: 900fps
d. 17 grains: 840fps
The steep drop off in velocity at the 17 grain mark is very telling of a load that needs more love.
Looking like 21 grains will sit in the 1025fps mark and 21.5 about the 1050fps mark.
Penetration test - try over 2 feet of wet clay before I got bored digging!
