I've got one of the SRT Integral 77/44's coming in with the Douglas 11 5/8", 1:11 Twist barrel and I need to try and work up some loads to see what the gun likes best. Anyone have any suggestions?
Subsonic .44 magnum loads?

Re: Subsonic .44 magnum loads?
What kind of bullets do you want to shoot?
My suggestion would be to get the heaviest 44 bullets you can find. I know 300 XTP's exist, I've made 460gr lead ones from a 500gr mould designed for 45 cal and then individually turned 20 thou off each bullet, sized and seated a gas check.
Look at Red Dot for a powder to use. It's very fast, and some people find it to be very dirty. In a suppressed, slow application like this it is surprisingly clean burning.
Start with them being supersonic and work backwards.
In my revolver I can shoot 240 LRN @ 1000fps with about 11gr of Unique. It goes supersonic from my dad's 20" barreled handi-rifle combo gun.

You can get some medium loads with the 300 grain bullets, like the XTP. I don't have my data with me, but there are some loads listed on the hide if you do a snipershide google search.

I've gotten several reloading manuals to work from but have this question, should I start with the pitsol loads and work forward or work backward from the rifle loads? I'm new to reloading so, any advice would be much appreciated.

Since you're running an 11+" barrel, you are 3" longer than the pistol loads. Most 44 mag rifle loads are with an 18". So, I'd lean to the pistol data. I'd add about 30-50 fps for the extra barrel length over the pistol data. That will get you close to figure out the velocity with the powder you plan to use.
