"when using the the .310 expander, case neck tension is not enough. As soon as the seater die gets the base of the bullet into the mouth, the bullet will almost drop into the case. If I use the .308 expander, it's kinda tricky to get the bullet started."
You have two distinct difficulties; over expanding and no mouth flare.
First, if the seated bullets are a loose fit, the expander is too large. Either use the smaller or reduce the diameter of the larger. I would use the .308.
Second, you need to flare the case mouths just a tad, the way cast bullet shooters do. I would use a Lyman "M" expander die for .30 cal. short rifles but Lee's Universal Expander die will also work. Either way, you need to expand the mouths enough to allow your bullets to start without catching on the case mouth.
