I have a Bartlein 20 cal barrel 10 twist, would make a good barrel for the 20 vartarg?
Yes. Vartarg is the answer to every 20 caliber question, and many 22 questions too.

Vartarg rocks...Adam Bentley is the smith to contact
Most folks use a 12 twist barrel. I just had two rifles rebarreled by Pac-Nor and went to the 11 twist barrel so I could use a little heavier bullet. Your 10 twist should work out great, especially for 40 grainers.
I have a 9 twist. It shoots 40s fantastically! I have some 55gn to try, just haven't yet. Them being discontinued took the wind out of my sails.
Well, I fell for the Vartarg once. I read all the hype, perused the load data showing fantastic efficiency and jumped on the band wagon.
Then I started looking for those velocity numbers everyone claimed. Couldn't even get close. The barrel was a great shooter but vartarg just wouldn't move like I thought it should've. It became the best shooting, most awesome bullet slinging, 204 Ruger I ever owned. Oh, that solved the velocity issue!
I can tell you why you were disappointed: you used a chronograph! Folks claiming big numbers are being silly. It's very efficient but it doesn't break the rules of the universe. It's like the guys claiming the 6.5x47 can match a 260 Remington. Simply not true; 10 grains of powder is A LOT of difference in velocity. But just as in this case, the smaller cartridge seems to shoot more consistently accurate with less effort.
I don't care how fast it shoots them, cause they make it to 300yards with plenty of oomph left and similar drift and drop as my 22-250 running 50 vmax at a moderate 3500fps. Mine shoots superbly accurate at that distance with 1" being an obtainable goal and most days yield at least one sub 0.5" group.
I am at 150 rds down the tube on my VT. I shoot 34gr dogtowns as they are cheap and they shoot. I screened it for the first time this week and averaged 3636 fps. I will take that with 18.5 grs powder and great accuracy.
been running a Vartarg for 12 years now.........although a 12 twist.....
still a favorite.....was a 204R in previous chamber
Looking at where the biggest VT fans live makes it appear the efficiency of the VT can provide speed as well IF you are out West.
There is a big difference in the abilities of rounds like VT and the 17 Ackley Hornet at high altitudes than here at 400' ASL. I love my 17AH but wish I had waited that one year so I could have done mine in 17HH.
Sometimes you just get a slow barrel or for whatever reason the brass won't hold up and shows pressure sooner.
Just for reference with my 20-221 AI I'm at 3735 fps with 32 vmax out of a 21" 11 twist. This is with 18.8 grains of H4198 and is a medium load.
I use a PacNor 10 twist barrel and am very happy with results with both 32 and 40 grain bullets.
