Those Loads...
Lloyd,
Here in central GA, the shooting is a year round event; any snow that we get is cause for rejoicing by the local population (mostly by the kids who get a day off from school if the weather even threatens to snow).
I've been wondering why you folks that hail from the north lands don't (maybe can't) shoot in winter. Seems like shooting in the snow would be fun, but, I don't live there, so I just don't know. Winter is prime shooting time here for me, as the weather is generally mild (although wet!)
What are your .41 and .45 loads that you are shooting? My favorite .41 load is a Lyman 410456 over about 18 grains of 2400. In the 45 Colt, I shoot a Lee 255 grain PB, but haven't found the optimal powder/boolit combo for my gun yet. I've tried various charges of Unique and WW231 so far. What I have on hand that I haven't tried yet is 2400, H110, Bullseye, and Herco.
I hope you enjoy that shooting trip.
