Subsonic - Suppressed 45-70

[kadams]

Has anyone casted some 400-500 grain soft 4570 boolits for hunting suppressed? if so could you share some suggestions on Molds. Id rather not reinvent the wheel. Also Id like to hear your results on actual game.

Thanks for any replies

Sub sonic with the heavier bullets will likely also be very close range and make a decent woods load. I've made up light loads to plink with at lower velocities, but never took them hunting or used a suppressor as no need to suppress my rifles for deer hunting.
I haven't found slower velocities that would be sub sonic to be all that accurate myself. I had to push them to a certain velocity to get decent accuracy, and that wasn't sub sonic anymore. Usually around 1300-1350 fpps.

gmdr.com has a lot of light loads listed and tested for accuracy in their test gun. They list the parameters so you can compare to your own situation.

I use TrailBoss a little, but I use pistol powders more. Mostly Red Dot. And all my subsonic 45/70 use cast bullets; personal choice, and I love to cast. Lyman's cast book has some data that gives the lower speeds, but I don't recall any actual subsonic data. That's where gmdr comes in.
