So far I have been using GreenDot as powder for reloading shotshells. I have to say I am happy with the results. The loads are fairly light and don't bruise up the shoulder, yet seem to smash the clays when I do my part.( AA hulls, WAA12 wads W209 primers, 18gr. powder, 1-1/8oz shot)
I am down to my last pound of it, and am wondering if I should experiment with some of the other powders. It is said that shot patterns may vary using other powders, some better, some worse, perhaps than I am using. Green Dot is a little pricey. A popular, lower price powder I have heard of is I think called 700x or 800x for target loads, when bought in bulk. They also seem to use less grains of powder per load, meaning more for your money!
I also have a chance to pick up a few pounds of some powder from a gun shop that is closing. They are pretty cheap and I may want to try them, just to see the differences. THey have Win 473, SR7625, WST, Win 540, Win 571, Herco, SR4756, RL15.
I have no data in 3 lyman manuals #2, #3, #4 for the RL15. I think this is more of a rifle powder.
Some of the above powders, I have listings for, are for fairly heavy shot charges, say for waterfowl loads, turkey, etc. I don't know if one could use less powder and make up a target load with these or not. Some, even for target loads, need large grain weight charges. These are obviously the slower powders.
What is the advantage of using fast vs slow powders?
Are some of the ones I have listed, ones you have used?
What were your results, pro's, con's, advice?
Thanks Bill
