The first shot out of a reallycold, cleanbarrel is the one that I'm the most interested in seeing. I do wonder if a warm barrel starts to affect the group size, and shooting out of a cold, clean one is the only way to determine if the load will fly true.
Even shooting in thesummer vs. thewinter can affect POI here in New England, soa hunting load can'treally be tested for until the cold weatherreturns. Our ML deer hunting season is in December and barrels canget icy cold. I guessthat you don't experiencethatshootingphenomenon in Louisianaveryoften, eh?
