The books show this cartridge will run on just about anything, and maybe even on a stiff charge of floor sweepings...
On hand (and let's stay there, please), I've got:
Varget
R15
H414
H4350
CFE223
H4895
... along with some others mentioned less frequently for that bullet in this cartridge:
TAC
Benchmark
H4831SC
R22
I worked-up loads for the 120 TTSX in this rifle, and found this:
R15: Good groups, but slow
Varget: Meh groups and velocity
H414: Crap groups & good velocity
CFE223: Fair groups, and excellent velocity
My question: is there anything I can extrapolate to the 140's, from the 120 results in this particular rifle? I was really surprised that neither R15 or Varget got me the velocity I was expecting with 120's. Could it be they'd be more suited to the 140's, than 120's? Or, would the 2 that got me velocity with the 120's, but more likely to do so with the 140's?
Or is it all simply a crap shoot, and I'll need to work up loads with all of them?
What says the peanut gallery? (I mean, besides, "You need to go out and buy ______ powder that you don't currently have!")
