Hello again Randy!
I use 8208 in a heavy 6 BR with a 30" barrel, not exactly the same as your pistol but I believe it will serve your needs as well. I began using 8208 when it was difficult to find Varget. I now have Varget but use it in other rifles.
Loads that are accurate and are currently being used in the 6 BR.
28.9 gr of IMR 8208 XBR with 105 Berger hybrid vel 2825 fps
35.5 gr of IMR 8208 XBR with 55 gr Nosler BT 3900 fps (you should see what this does to the rock rats in our area)
