Anybody have a favorit handload with this powder in 30-06?

Was givin a pound of IMR-3031, must be at least 20+ yrs old, still smells good.
Have some 190gr bullets, and loaded them with 32gr of IMR-3031.

Shooting them out a 03 Springfield.
Keep it on the low end, for now!
 
Not for that bullet weight.
All my data is for 160 and 175gr cast bullets.

My suggestion......
Use the Lee manual "formula" for determining a reduced load, based on IMR-3031 data and a recommended 2,150fps.
ie: data reduced to give approx. 2,150fps
I used this to determine load for 155gr PtGC that shot really well. About 34.0gr if my memory serves me well (don't trust it, I don't!)

I've found this to be accuracy level with my .30/06 (now rebarreled to .338/06) with 175gr Lee FNGC (as cast weight)and my .30wcf.(aka .30/30) with 160gr FNGC (also as cast, cataloged as 150gr), and IMR-3031 the preferred powder.

Killed white-tail doe DRT with the 160gr Lee FNGC with 31.0gr of IMR-3031 this past Sat. was a week ago. Single shot from Glenfield 30 (.30wcf) at 95yds. Could eat almost up to bullet hole. (Blew out 1" section of spine!).
Talk about an easy to remember formula!

.30/30, IMR3031, 30 or 31gr of powder !!! Bullet sized to .310-.311"

I worked this up in a Savage mod340 I had back in early '80's. That bolt gun with 6-groove barrel would shoot 3 shots under 1" with this load. It works well in microgroove barrels when sized to .311.
FWIW: My '06 with 4 groove barrel also preferred .311" bullets to .308 or .309".
