You'll like the Wolf. Someone on the Black Powder forum has mentioned it loves the powerbelts, too, but I've not tried 'em, probably won't as I don't need the extra range and the things are expensive. They did prove it with pix of a 100 yard one hole group, though.
The other downside of BH209 is cost.
Yeah, the exorbitant cost is another reason not to like the stuff. But, I simply do NOT like the fact that I have to dribble 5 grains of Pyrodex next to the 209 primer to get the stuff to reliably ignite in my Wolf. I suppose CVA just started offering the breach plug, didn't know about it. I'd cleaned out my breach plug with a tip cleaner, didn't help much. I bought the Buckhorn 209 several years back to try in it. The stuff was relatively new at that time. I was NOT impressed. I'd been wanting something less corrosive, but not at the cost of ignition reliability. I'll keep shooting 777 in the Wolf, though. It works great and cleaning that rifle is NO sweat what with the removable breech plug.
Do NOT try Buckhorn 209 in a side lock. You'll be pulling the ball if you do. It will NOT go off. Buckhorn can acknowledges this with a warning on the label. Again, I lament the fact that I cannot get REAL black powder. I used to shoot Dupont and Goex in my revolvers back in the days before the law prohibited reasonable shipment and storage. I'm probably going to start making my own soon, though. Seems like a fun, easy, and safe (if you ain't an idiot) thing to do and I'm retired with time on my hands.
Let's just say it's a lot easier and safer than trying to make 2,4,6 trinitrotoluene. Making it saves the hazmat charges and I can make small quantities at a time. If you get interested in THAT, go to the black powder forum and search it, much discussion there.
But, nothing wrong with Pyrodex or 777 in the inline. Neither of those ignites as easy as holy black, though.
But, I've converted my Hawken Hunter Carbine to fire small rifle primers to deal with Pyrodex in that gun years ago. That gizmo is no longer available. I have found that one can dribble a few grains of Pyrodex under the nipple to avoid the hang and misfires on the sidelocks, but I wouldn't have that problem with holy black. Now, with Buckhorn 209, I'd need to light my cutting torch and remove the nipple.
See, I've been around and around with this ignition thing in my sidelocks, so I'm kinda touchy about such.
I'll leave all the Buckhorn 209 for you guys, though. I don't mind the clean up, just been part of the black powder routine for me since I got my first cap and ball in 1973. I'm used to it. A little soap and hot water, blow dry and lube, good to go.
