with black powder being extremely scarce in my neck of the woods i opened up my touch hole liner a bit with a drill and tried shooting 100 grains pyrodex in my .54 GPR primed with goex 3f and it shoots everytime with good accuracy but does not ignite as quickly as real blackpowder, about a 1 second delay and you can hear it go....FIZZZZ.... before ignition which is very distracting. I was wondering if anyone can give me any info on velocities or just on pyrodex in general as it appears to be the only thing i can buy around here. I can forsee a time when our government makes black powder illegal here in canada as they are sure shovelling a lot of manure down our throats with these new gun laws and gun registration we have up here.
