I have only tried one powder so far 4831SC and it is performing well but I haven't had an optimal day for shooting conditions (windy).
For 4831SC, I loaded 10 rounds of each of 50.0, 50.5, 51.0, and 51.5 seated touching the lands.
The 50.5 gr. loads performed the best on paper as well as providing the smallest velocity spread. The average velocity is 2758 with a 12fps extreme spread. As I increased velocity to 51.0 and 51.5, the groups opened up some as did the extreme spread. I am going to stick with the 50.5 load for now and develop / calibrate a ballistics curve for my Idaho antelope hunt in September. I am confident that the 50.5 load will shoot better than 1/2" per below in calm shooting conditions if I do my part.
I was hoping for a faster load but I may have to try a different powder at some point. I just don't have a lot of spare time to keep fiddling with powders and loads before the hunt.
I would check the laws about using the suppressor. I think it will be illegal to hunt with it attached.
Just incase you don't know this (????). When using a suppressor the report of your rifle will only be silenced when you are shooting ammo that is subsonic. It might be dangerous to load way down to get subsonic velocities.
