Shooting the Martini Henry Sportster .450/.577 and Mauser 1871 single shot black powder rifle

One thing I forgot to mention about BPCR loading and shooting is to remind of the requirement to clean both the bore and the brass after shooting. It’s a well known requirement for both muzzleloaders and BPCR guns including the use of many of the BP substitutes. Some of worst, sewer pipe bores I’ve ever seen were those that have been shot with Pyrodex then neglected. This cleaning requirement also applies to the Russian duplex loads that typically use only the small amount of 5 or 6 gr of BP. After shooting, I thoroughly clean and re-oil the rifle’s bore. I decap the brass, clean with bottle brush in hot soapy water, rinse and let dry.

I wonder if a load could be worked up with Blackhorn 209? It’s a much cleaner burning BP substitute than either BP or Pyrodex.

That's a new powder to me. I must read up on it.

Re after range cleaning. I found a couple of nitro for black shots after a BP session were a great aid to bore cleaning.

I used 11grn VV-110 in turned brass cases

Yes absolutely! Blackhorn works great as a BP sub, one of the best. Far Superior to Pyrodex which is one of the worst, But Blackhorn is hard to find in many locations and is a tad expensive. Have to order and ship here.

My recently acquired MH 577-450 was originally stored in an armory in India, Brits sent a lot of these onto Nepal in 1908 as more 303s were becoming available. This one has 1908 Nepal date.
