I don't see what powder you were using, I suspect H110. I shoot 21.0 gr. of H110 out of my Maxi Trapper behind the Hornady 180 gr. SSP, and I am getting 1885 fps.
I am trying to find some load info for the Hornady 140 gr. FTX in the Maxi, no luck so far. I'd really like to get a good load for that bullet to use as a long range (relative) varmint load in the Maxi. I am envisioning an Armadillo going "POOF!" at 150-175 yards...
