45-70 cast hunting load

[JeffreyDeGraff]

Ive loaded for 45-70 for probably 25 years. Ive mostly loaded jacketed bullets on the high end with lever action and ruger #1 data, with great success. Ive got a hankering to dust my old H&R buffalo classic out and start playing with her again. Ive got a great load with 500gr cast bullets for this rifle, but was thinking I’d like to go with a 405gr cast bullet this time around. I’d like to keep pressures in the trapdoor realm even though the rifle can handle hotter. I’m not looking for an anemic target round, but something good for hunting that I will plink with too. What powder and 405gr cast bullets have you guys had good performance with in the lighter loads?

I'm away from my data for a while but IMR3031 does well with a lot of velocities. I'm using it for 405gr cast powder coated in 45-70 and 458socom.

I was using Missouri Bullet Company 405gr cast coated bullets with Accurate 2015.

405 cast performance over reloder 7 Not sure if that powder will go low enough for what your after though.

I found a load of 16.0gr of unique with 405gr cast. Has anyone ever tried this?

A lot of people like that combination.
Don't dismiss Trail Boss either. That velocity with that bullet is formidable if you were on the receiving end.

I have had good results from AAC-5744 using the Lyman 458124 bullet.

I have shot that bullet with Trail Boss. I dont have a chrono, do you know the approximate velocity?

Hodgdon's data with a 24" barrel using 12.0gr of TrailBoss gets 971fps, 13.0gr gets 1007fps.
