Not sure why people come on here, when they clearly do not use or like subs, other than to piss somebody off! Let me make it clear that i would tamp a load of pig **** down the barrel if i thought it would work. I shoot everything. Sub smokeless black whatever is available. Black here is $50 lb. Pyrodex RS is $30 lb - Select is $36 lb Smokeless is $47 - $50 lb. There is enough of a reason for using sub not to mention the fact that you get more shots from a pound of pyrodex than a pound of Black. The last few years there has been a shortage of powder here in Canada. It forced a lot of people to try different powders and that was a good thing. Now i have loads worked up for several different smokeless powders. As far as muzzleloading and BP cartridge i never had a problem finding subs close by but black is a whole other story. And i find them to work in my 45-70 as good as the black and smokeless. Availability and cost are the main drivers for my decision on what i use and i am sure it is for others. I guess the point here is run what you like. If you want come here to start a fight please go else where.
