Subsonic .308 data?

[clintbailey]

TrailBoss powder makes subs in rifle cases a lot easier, due to its fill capacity from what I hear. I have loaded 308 subs using TB and 170 gr FP bullets (usually for 30-30). @swampratt does the Red Dot have enough capacity to not need a filler on top?

I have never used filler with Red Dot as what I read was it was not sensitive to case position my accuracy was excellent with small amounts of it in a large case so I never tried fillers.

.3 cc scoop which is very small just 2.0 gr of powder it is not bulky.

Red Dot is fast powder maybe that is why it works well for me without a case filler.
