150 grn bullet? Why don't you use a 250 grn SST/Shockwave like the rest of us? Hodgdon has/had a M-L guide that listed speeds with various loads of their 777 & Pyrodex. I'll bet that info is somewhere on their website. It would be a little something to go on. I find speeds a lot of times are slower than those listed. I chrony'ed my loads last Fall & got a steady 1950 fps with 120 grns of B209 & a 250 grn SST out of a 26" Knight.

 

sorry, i meant powder, not bullett. i do use the 250gr shockwave

have you checked TC's website? I thought that they had some load data on there. Since 150gr powder and 250gr Shockwave is popular I would think that they would have it.

Also I know that my TC Triumph manual had some load data in it too.
