My goodness, 5.7x28 is frustrating

I believe I have finally dialed in the resizing of the brass. I was having difficulty pushing the shoulder back to .910 and the neck to .954. Plus the Hornady shell holder I was using was deforming the base of the case, so now I have the MK custom shell holder and that fixed that. I am having difficulty now with seating the 40 V-Max bullet. It will not fit completely in the case gauge. I have played with different seating depths to see if that would help, and it is hit or miss. I do trim the necks which I have also played with different lengths to see if that makes a difference. A few of the rounds have fit, but then I load another after having success and that one doesn't fit. ::FF:: Any suggestions? I am using the RCBS 2 set dies with the Lee classic turret (indexing rod removed). Thanks.
