Thread: Subsonic 30-30

I'd like to know more. Does one one need to add a filler aka black powder style or do you simply load with 7.5gr trail boss?

Just the Trailboss, no filler needed, the Trailboss is quite bulky, if I recall correctly a case filled to the bottom of the neck was about 10 grains for 30-30 and 15 for 308. Standard large rifle primers.
7.5 grains is also the subsonic load in my 1:12 twist 308.

I checked my notes, it's 11 grains to the bottom of the neck for the 30-30.
