Hi!

Just taking my first furtive steps into the world of BP with a Martini Henry. Just reloaded some cartridges last night with Pyrodex RS, but my understanding is its more volatile than BP (up to 30% more) so I used this handy site to do a conversion

Sure the more (way more!) experienced members on here will have something to say though...

If you don't hear from me after I shoot it this Sunday, you know I got it wrong ;-)
