I didn't think you could shoot black horn in a sidelock.
Ive got a Green Mountain LRH .45 barrel and a Mag Spark on my Renegade and have shot bh209. I dont believe my setup is unsafe. I dont shoot it around others tho, so just me at risk.
No because it is a sealed unit, get a extra cap cause if you lose it get your flint lock ! Also very important (IF) you do as I say you will have no complaints , stik the 209 in your mouth insert in Magspark /then spit in cap and close it up and your done ! Most complaints come from ignoring what I've learned and it can be difficult to remove if you skip this step ,an added benefit this is now a sealed unit and with a taped muzzle water proof and kept outside good for however long your season lasts /plus as being sealed I do not get gas cutting/erosion incurred with percussion caps (why Ned Roberts )invented a similar ignition (ahead of his time) . Use never seize and install and unless you damage it ( drop the hammer with out the cap) been there done that I do not remove them till I do screw up threads ,some rifles have the same 5-6 yrs later ! /Ed
