Note that Alliant has listed very similar 7/8oz loads with various hulls, primers & wads in the "Additional Target Loads" section of their reloaders guides for at least 15 years, probably longer. These loads utilized Bullseye & Red Dot in years past, don't have an up-to-date guide.
Note also the 7K minimum I have basically adopted & have recommended applies to general purpose loads which may be used under varying climatic conditions, especially for cold weather use. While undoubtably all powders are affected to some extent by low temps thos in the "Fast" range are less so. These loads acheive their low pressures by sing a light shot chare at normal vekocities.
I still strongly advise "NOT" to try & acheive still lower pressures by switching to slow burning powders. This was brought home to be by the dramatic failure in the lead shot days, in a duck swamp by a load of 7625 behind 1¼ oz shot at a low pressure. Such use had been highly tooted by none other than Ross Seyfried as a "Damascus" shooters dream come true. Proved to be my "Nightmare"
I would have no problem with using a 7/8oz load with Red Dot for any use this load would be applicable, though my personal preference is if going below an ounce I prefer a smaller gauge.
