Season's Greetings All - I am hoping for advice on loads (target/plinking) for a Martini-Henry carbine, using a 122gr cast projectile sized to .313 (maybe not ideal choice, but I happen to have a pile!). I would prefer not to bother with gas checks, so lower velocity is not really a problem? Red Dot? Blue Dot?
I am assuming a "filler" of some sort will be needed though, and any suggestions there would be welcome too!
Cheers from out in the Mallee scrub,
