I found a solution when the .40 cal. was brought into production, having only a dedicated 10mm die set, I was unable to use the powder thru die to bell the case mouths, cause the brass wasn't long enough to reach the belling feature. So I started using a different method, something I've discussed in several other threads, I won't elaborate at this time. I'll just say this, I discovered a way to seat bullets without having to bell, so no crimp was necessary.
And in all honesty, if I'm just loading a small batch of 100 or so, I don't mind skipping the belling step, kind of prefer it actually. But it is some what cumbersome to load / seat large batches of 300+ bullets without belling, so it has been a bit more time consuming, even when chamfering the inside of the mouth to help the bullet seat straight and without shaving, is some what more tedious.
Update, a few days ago I had to do a batch of a thousand rounds of .40 cal and wasn't too thrilled about the additional time and effort that would be necessary. So, I devised a method of solving this problem with my current 10mm die when loading .40 cal. as follows:
I took my Lee 10mm powder die apart, added a sized and evenly trimmed piece of brass to the inside to use as a spacer between the belling stem, and the threaded adjustment knob on top. This allowed for the stem to reach down far enough to attain completely normal belling function. It worked perfectly, and solved my long time short coming (pun intended) when loading .40 cal. with the dedicated 10mm die set. I would venture to guess this could be adapted to function with most common die's, but I haven't tried it with RCBS as yet.
As for other die sets of similar design and dedicated to one specific longer cartridge, the method I used could probably be applied by using just about anything metallic and that has or can be fashioned to dimensional characteristic that would serve as a spacer. If too long, a piece of 44 special brass trimmed down to a functional length, it would likely work just fine.
