I rolled up about 30 cartridges, with sized .577 Minies hot lubed with Alox / Beeswax. Basically a knockoff of the "Javelina " or whatever it is.
60 grains of Triple 7 "2f"
Every round ignited instantly with Rio musket caps, no stubborn ignition . The last Minie went down as smooth as the first . No crud ring like the 777 3f gave me in my Pedersoli.
It was my first time out with this Euroarms Zouave I got from a fellow member. Some rifles like 777, some don't. Zouave repros , in my experience, do well with igniting subs with their direct flash channel. Repro 61 Springfields like my ArmiSport get hinky with subs.
Accuracy was good, fouling was nonexistent and everything went boom. I love the Holy Black and you can't replace it, and I shoot lots of BP but the subs can be convenient for a quick range trip. There's no doubt about that. Plus I can grab 777 at my local sporting goods stores.
The Alox played nice with the Triple 7, since Triple 7 lives in some weird lawless zone in between blackpowder and semi-smokeless.
Cleanup was a breeze, my flash channel is spotless and I left the range with a clean rifle after 5 minutes of work.
