After one of those embarasing happenings on a "Cold" winter duck hunt with a load taken directly from the powder makers data @ a 7K psi level, I no longer go afield with loads showing less than about 8K & use the fastest powder & hottest primer which can be loaded to a desirable load within those parameters. Have had no problems since adapting this criteria. I have noted over the years that Hercules/Alliant data has showed an "Extremely Limited" number of loads with less than about 7500 psi & these were always listed as "Target" loads. Reckon there may have been a reason?? Other makers did not seem to be quite so "Honest", which resulted in my embarasing moment. The load had been a particularly effective one "Untill" the temps dropped. This load incidently used a rather slow powder in combination with a mild primer but was a 1¼oz (12ga) load & in the makers "Field" section, not a load developed for clay target shooting.
