of the pyro vs. Holy Black debate. I have used both with good results in both a Flintlock and Cap rifles. I have used P-dex crushed to my liking in pans with similar results to B.P. but it got the job done. I have never had a situation where neither had performed as expected. Shot is shot and meat is meat. for some to dismiss it usage outright to me is ignorance . Some may have tried it and had no problems, maybe you should revisit. but when it came down to completing the task t at hand it did its job. in the end clean your implements of hunting. JMHO
