I bought 16 lb of it to try and probably won't buy again. It is pretty dirty, especially if you use lighter loads. I have been loading heavier 1 oz loads lately, and have not had any problems shooting them in the Montana Winter. I really like Clay dot and may go back to that. Promo is ok, but not great.
I changed from 700X to promo about 3 years ago, I like it. I clean my guns after shooting and truly don't feel that it is dirty. If you can break a target with red dot, 700X, clays, green dot, solo or whatever you can break it with promo for less money. All powder varies a little so always check weights promo may vary a little more, however in 3 years I haven't seen it change enough to be a problem. I would suggest buy or borrow a little and try it.
Promo dirty? If you are not shooting gas guns, so what? I clean every 300 rounds whether the Ljutic needs it or not. I've on my fourth jug of Promo now.
I am admittedly cheap and cannot rationalize spending more $ for the same results. Same reason I use one ounce of good clean reclaimed shot for singles and my short yardage 'caps. I can't discern any difference in my scores and it allows more shooting. More shooting may allow me to shoot from longer yardage and then I'll think about ounce and an eight of better quality shot for 'caps.
I tried 8lbs of Promo and went back to Red Dot.
Powder drops seemed inconsistent and it was kind of dirtier.
But it did work well with the el-cheapo primers and reclaimed shot that I used with it. I haven't loaded shells that cheaply in years.
And yes Red Dot goes with paper hulls and paper basewads like peanut butter goes with jelly.
Don, consider using e3. Alliant reduced the price to that charged for Red Dot, and you use less of it. For 7/8, 1 and light 1 1/8oz loads it is the best of the Red Dot, Promo, Clay Dot, Extra Lite, e3 bunch. I also like it better than Clays, which I will use up for 45 ACP loads.
I have been loading clay dot for a few years. I am getting down to only a few pounds left. Yesterday I bought two jugs of promo to try. I really like clay dot but I went with promo because it is suppost to be more dense. I have a bunch of claybuster fig 8 wads I want to use up. They are longer than the Remington fig 8 I have been useing with clay dot. I was not getting good crimps using 17.7 grains of clay dot, sts hulls and the 1 1/8oz claybuster fig 8 wad. So, I figured I would try promo cause it takes up a little less room. Everyone I spoke to that has used promo have been very happy with it.
