That's the post that I was looking for, and I already have 5744.

Is that still subsonic? Quick Load says 9.3 gr 5744 gives 1050 fps. I'm hoping that Quick Load is wrong, I substituted the 220 gr Hornady RN for the 225 gr OSB.

Outlaw State Bullets has me looking at the Roosky Whisper again.

Thanks for posting that Dick.

I haven't put that load over a crony yet! But in the back yard you can realy tell if your breaking the sound barrier, groups so far have been between 1.25" and 1.5" worst about 2" @ 100 Yards.
