I am happy with it. I could probably get tighter groups with 100 grain vs 110 grain, but if I need to take a long shot with the Barnes Spifire TMZ, I like having 110 grains of powder and velocity exceeding 2000 fps to get it out there as flat as possible.
Did you chronograph this load? If not, you really don't know what (if any) difference the 10 grains of powder will make.
I know that with my TC Triumph, I got exactly the same size groups with the same point of impact with 100 gr or with 110 grain. The only reason I'm shooting 110 grain is I bought a couple boxes of 30 grain pellets at about 75% OFF. I'll shoot two 30s and one 50 till the pellets are gone, then I'm going back to loose powder.
Back in the old days, when I shot primitive shooting matches with the mountain man club, my 50 calibre percussion rifle's two best accuracy loads with patched round ball were 95 grains and 39 grains ffg. No idea why. I shot the 39 grain loads for the targets at 25 yards or less, and the 95 gr load for longer competions and for deer hunting.
Ever shoot a squirrel with a 50 caliber? I've tried it three times and got all the squirrels. Sure makes mush of their heads!
