New poster, long time lurker. I felt compelled to comment on the above It does produce impressive velocity but it is definitely faster in burn rate than RL-25 - much closer to RL-22, in fact. It builds pressure differently and seems to be very well-suited for use in large capacity cases, but it is absolutely not in the same burn rate neighborhood as RL-22
I've used RL-26 in my 257--270--7mm Weatherby mags and have the same opinion. It is much closed to RL-22 in burn rate than RL-25. But it does produce impressive velocity.
Agreed. Much closer to RL-22 than RL-25, at least in my 257--270--7mm Weatherby mags.
