Has anyone tried either of these powders in their 6.5mm Sherman Long (the one formed from .270 Win. brass)?
Ramshot LRT and/or US 869 in a 6.5 Sherman Long?

I use RL23 in my Dad's 270 Sherman. Running 148gr Hammers at 3000'.
Bullet?

140 grain SP or BTSP types.
It's not a typical bullet/powder combination that 6.5 Sherman owners load, but here's a baseline that might help you: https://shermanwildcatcartridges.com/sherman-load-data. You might also use loads for 6.5-06 (https://hodgdonreloading.com/rldc/?t=1). LRT and US869 might be too slow, but it does not mean it will not work. Good luck!

Would you know if Ramshot LRT is as slow burning as US 869?
US869 is much slower.

Ramshot magnum or reloder 26 has produced the best results with Berger bullets ranging from 140 to 156.

I had to go back & check my records as I knew I ran a pressure test with LRT in my 6.5SS. I ran 62-70grs. with a 160 Matrix, Norma brass, WLR primer, & no issues in my set up. Slightly flat primer but no stiff bolt lift & all went in about a 1 MOA group @ 100yds. I never went further to develop a final load development.
