I snubbed them till I shot one, and it made me embarrased to own a Gold Cup....The 52-2 Master is the firearms equiv of a lead laser. You do have to load specific 148gr ammo, and having a set of recoil calibration springs is a must. Once you dial it in with a load, 38spc wadcutter is a no brainer to load and very forgiving. (I don't get the expensive to feed post, 2.8 of Bullseye under a 148gr cast solid base WC, wheel weight +5 zinc...Leave about 15 thou protruding and a mild crimp. Brass lasts forever it seems. I will admit I never actually used store bought ammo). I spent a year playing with one and have mucho respect for them.
BTW...We were in Bandera, Kerrville, Lukenbach last week, and if the schedule wasn't so hectic I would have treated to Mamacita's. Next time for sure. Todd
