Hello,
So a couple years ago I bought a 1858 Remmy. With an 8 inch barrel. Settled on for a hunting load 40grains of 777fffg. With Johnston and Dow conicals. Gets going to
40grn 777 217 jd, 960fps SD:20 es:70
40grn 777 140 rb 1229fps Sd:70 es:170
Last year I bought a 12 inch target barrel for it and installed.with the extra length I’ve only increased to
jd: 1030fps Sd:17 es:50,
rb: 1255fps Sd:50 es147
Has anyone ever tried 2ffg 777 in a cap and ball Revolver? I’m curious if the very little increase in velocity is because the powder is done burning. I don’t want to add too much more powder in there. With 777 it doesn’t compress as much as regular pyrodex so it’s about 1/8th below flush.
3f pyrodex I can squeeze 50grn 140rb 1207fps and it’s seating depth will vary. Also seems to kick more violently then the 40grn 777. And I think strains the loading lever to compress it.
Im curious if the longer length can take advantage of the slower burn of 2f. But don’t know if 2f generates higher pressure to start then 3f? Anyone tried this before I buy powder that if it doesn’t work I’ll never use?
