I have ran up to 66gr(starting to show pressure) in my 6mm Saum with 115 dtac. I have long ass freebore so bullet robs minimal powder space. Have also used it in 65 Saum with 156s, 61.5gr was 3090fps, no pressure. In the 25, depending in you're freebore, I'd start around 60-61gr.
@NICETRY what's short cut? You referring to N568? I have found it vastly different in energy/gr than N570. Notably less velocity, but cooler burning. Higher case fill VS N570 on a fps scale. Tried it in 300norma and 257wby sized 25ca wildcat.
