No, this will not work with any bullet as the twist rate is too slow. If you want to shoot subsonic loads and heavier bullets you will need a faster twist. I would not use anything other then 1:8.
Now, the twist you are looking at is even a little slower then most 300-Whispers for supersonic loads so it may not even shoot supersonic bullets all that accurately.
I would buy a different barrel! If yu must use it, I expect it will work besy with the lightest bullets you can load at the highest velocity possible. Out of a pistol barrel, that is a tough combo to get! TC barrels made for supersonic loads are a 1:10 twist to give you a starting point.
