I have been having fun shooting Lee 7/8 oz. slugs with a modest load of powder (makes nice big holes in paper). I would like to begin testing some slugs from Ballistic Products and it seems that Longshot powder will give speeds more suited to hunt deer. In their slug loading manual BP makes comments about cold weather shooting and slow burning powder, and Longshot is toward the slow end of the spectrum. Any thoughts on the suitability of combining November weather (approx. 25 to 40 degrees) and Longshot powder? Any tech info would be appreciated. Thanks in advance.......
