Glad the addition of a small amount of smokeless to BP loads has worked out well for those of you that pursue our sport from that angle.
Just wanted to remind one and all that duplexing of smokeless powders can be very dangerous as is emphasized in most reloading manuals I have had occasion to read during the last 65 years.
From what I have read when you duplex smokeless powders you may very well experience large pressure spikes from the combination of two or more smokeless powder. Best advise I can give for one and all is DON'T pursue this type of activity unless your wish to be carried by 6 for a hastened DEPARTURE.
