I have not been able to find Black Horn,, I've checked every time I've caught a note here,thanks encore for posting!hard for me to go from 10 to 15 lb a year to nothing,, I have managed to stock up on smokeless supplies enough to get me shooting again,, I lucked up on 30 cans of Sr 4759, and managed to get 10 lb of imr4198 from Bruno's and I'm full of primers,, would love to be doing some Black Horn shooting but for now those rifles stay in the closet, it's not very reassuring when every sales rep I called and talk to tell me that the three calls before mine were all asking for Black Horn,,,, not a whole lot of black horn shooters down here in Southeast Texas wish I could come up on someone to do a little horse trading with,, I've been a one powder shooter with all of my smokeless experience so I'm using this time to experiment with other powders, for all of you old 50 cal smokeless shooters understand that that sr4759 was a great powder,, really good luck with it so far out of a Bruxs 28 twists,,, I've come to the conclusion I'm just going to quit frantically searching for blackhorn and just wait for it to come back around, problem is I had such great plans for blackhorn this year,,, everything in time..
