With lead shot it's not as critical for the higher velocities like as with steel being lighter around 7.8 g/cc. Longshot is a fabulous 1.25oz 1400 fps late season pheasant load powder though.
When it comes to target loads Red Dot is a favorite for lite 12 gauge target loads. Back in the day when used to load a lot of 12 gauge target loads I used it for standard velocity 1,200 fps 1 oz loads and when I wanted to be more economical and strech my shot a little farther I'd load 7/8oz loads.
I always prefered the slightly slower burning Green Dot for the faster or heavier target/field loads.
Being that lead shot is quite a bit more expensive these days, Red Dot makes excellent 7/8 and 1 oz 12 gauge loads.
