I've been messing around with shooting black powder 45-70 cartridges out of my browning 1886.
Using duplex loads I was able to make some accurate loads that would put all the shots in a 4 inch group at 100 meters ( good enough for hunting ).
I've stopped duplexing as I want to make cartridges with just black powder , I've tried graphs , goex and old eynsford. I was able to get the Old eynesford 3f ( 55gr ) and my cast 405gr Saeco bullet to print a ragged hole at 50 meters but it opens up to around 5-6 at 100 meters. I'm using over powder wads from cabellas and home made black powder lube with natural bees wax.
Does anyone have a load that works for them ? I'm getting a little frustrated trying to get this rifle and black powder working together.
