Triple Seven - again????
I am playing with Triple Seven again - can't find any BP.
1884 Trapdoor Rifle 45-70:
Trying some 405g HB Lee bullets I have cast with 42gr (by weight) of 777 with a large rifle primer in Starline brass.
Seating the bullet to the bottom of the top driving band and slightly compressing the powder (.100 max). Not using a wad under the bullet.
Bullet alloy mixed at 16:1 - testing out at 10-11 BH.
If I can find the paper I will post group size.
Anyone else have experience with this stuff?
