I use the Lee Prime-all for the same calibers, so far I have not noticed a problem with mine. The 357/38 do tend to be a little easier to seat than the 45 but not enough to cause worry.
Hope you can figure it out
Oops I misread.You said Auto Prime
Does it use seperate feeders for small/large primers?
