It was cold today, gauge on the car showed 32F as I pulled up to the pistol range at TCGC this morning for a quick shoot. Blue skies, no wind. I'd loaded some Acc #7 8.7 gr with Berry's 115gr RN 9mm that was the same as I'd shot last weekend with some success. Today....phew, where's that barn door boss? I was getting a drop of close to 12"-14" at 25 yards, with a recipe, that the weekend before, had given me a pretty flat and accurate trajectory for the same bullet, same distance. So, I did what anyone would do under the circumstance...and threw a couple of mags in my pants pockets and 'snuggled' them somewhere warm while I stood in the sun in a feeble attempt to get some warmth from it. Next ten rounds started in about the right place, and then, as the cold got to them (I was not rapid firing obviously) each shot got lower and lower!? Mmmm! Next mag...something similar. Can anyone share their own thoughts on cold weather shooting/reloading and powder choices?
