Hi All,
The answer is...11.
Rifle:
BL-C(2), good loads on my 30TC, 7mm-08, and 257 Roberts
H414, good loads on my 7mm-08, fair and still tweaking 257 Roberts
Hunter, good and still tweaking on 257 Roberts, just starting with 7mm-08
No luck so far with H4350, R19, IMR4064.
I see a trend here. I'm not having luck with the extruded powders and doing o.k. with ball. The BL-C(2) is so good in the 30TC I haven't bothered to try anything else. I'm hoping that Hunter can replicate or improve upon H414 so that I can settle on just the one powder for 7mm-08 and 257 Roberts. If that works out I'll just build decent loads with the extruded powders and not replace them when they run out...until I get tempted by R17 or IMR4831 or...
Pistol:
Bullseye, good with 380 auto, o.k with 9mm and 45 ACP
Power Pistol, good with 9mm, o.k. with 380 auto and 45 ACP
Titegroup, good with 9mm and 45 ACP, can't easily measure for 380 with my equipment.
AA#7, o.k. with 45 ACP, not so great with 9mm
Blue Dot - loaded some 45 ACP just to have high flash.
I'm less fussy with the pistol powders, probably because any accuracy problems caused by powder/primer/bullet are overwhelmed by problems caused by the shooter!
