I am looking to work up a load for 140gr Hornady SST's 270 Win with IMR4350. The others powders Varget and IMR4064 don't show as powders to use on their app. Anyone have a recipe that has worked for them to give me a starting point for what I have to work with?

I have already worked up a load for Sierra 130g SBT GameKings.

That was my go-to comb in 270win. I haven't loaded any 140's yet to help out.
 
I use Superformance with 145 ELD-X bullets, as well as the Hornady 140 Interlocks. Start at 54 grains and work up from there. This combo is laser beam accurate in both of my rifles with the loads that I have settled on, and impressive ballistic performance.
 
I agree. I use IMR4350 on my 270 130s. 54grs. Runs just over 3000fps . Would step back to 52 and work back up. Shooting 145 eldx in my other 270, shot very well also. Both are 1:10
I already have my IMR4350 130's dialed in the the GameKing at 55gr. That's a 3 shot group below for the round out of my Rem 700ADL with 24" barrel.

Working up the 140's now.

You have any other powders available? Heavier than 130g I usually go for a slower powder. Shooting Hornady 140 BT with 59g Rel 22 in 22" barrel. You may want to work up to that though. Chrono said 3150 but I need to recheck it.
 
Start few grains under your 130 load and work up
Max load for the 140gr is 53grs. I started there and went down 1% from each level which is anywhere from 4-6grs. I went back for 10 rounds to 48.9grs. I will be shooting them next Monday to see how each groups with a 3 shot group. When I find the sweet spot(s) I will go up to 5 rounds.
