Cris,
I have a couple suggestions. The first is try sizing the cases with the expander assembly removed to see if they then hold .358" bullets (a FL sizing die sizes the neck to a smaller than required diameter and the expander then opens it back up). If you are lucky, you might be able to avoid the second sizing operation. I use this trick with several calibers. You may have to bell the cases, but a shop made button in an extra "m" die will take care of that or an extra 38 spec expander button in an "m" die will work if adjusted to just bell the cases. I made my 2 die 9.3x 72R set into a 3-die set this way. Fillers are very controversial, but I found I can get uniform velocities when using a tuft of kapok tamped down on the powder charge. You will have to decide for yourself whether to use a filler or not, but if you do, don't just add it to an established load. You need to reduce the load and work it back up with the filler. I couldn't read the bottom line in the proof load stamped on the barrel, but it will tell you what bullet it was proofed for. If you use the filler your velocity may increase to your target level.
