When I read your original question RL 26 was my first thought. As I read the comments it was others opinion too. I’m getting 2900 with a 180 gr partition in my 24” 30-06 with 63.5 gr of RL 26 (compressed, work up). Also getting 3070 in a new 26” barrel of my 7mm Rem mag with 66 gr of RL 26 with a 150 gr TTSX. And 65 gr of RL 26 with a 180 gr ELDm in the same gun mid 2900’s. I suspect my new barrel will speed up.
Not 284 data but giving an idea capacity to weight velocity. Good luck. Ken
