My problem was that pulled tokarev bullets that I put into my Starline, French long cases which were crimped in the CH4D set, had poor neck tension. What happened was I could take a reloaded cartridge, place it bullet down on the table, and push down on the cartridge and the bullet would slide back into the case. The factory Steinel ammo with .308 bullets & Starline brass does not do this. Likewise, the original .32 French Long, steel case cartridges do not do this. If I use the .309 pulled bullets from thee French ammo it does not do this unless I have an out of spec bullet. I found 2 of my reloaded rounds that slid back, but the bullet diameter measures .306 inch. I believe these French bullets were out of spec or crimped/deformed too much in the original French ammo.
After finding this out, I now measure each pulled bullet from my French Long, ammunition to be sure its at .309 prior to its use in reloading. So I have a neck tension issue with the die set if I use .308 or less diameter ammo. That is why I want to get some sort crimp die that goes to .308, to insure a better crimp on my reloaded French Long ammo using factory Starline brass with pulled Polish Tokarev bullets. Steinel uses .308 inch M1 carbine bullets. Or I avoid small bullets and use the .309 Hornady XTP 90 grain bullets. I got tons of split Polish tok ammo (.307/.308) and 900 rounds (.309) of dead primer, original French ammo and would like to use those pulled bullets in reloading if I can find a .307/.308 crimp die that works on the French long cartridge.
Comment, suggestions, criticisms is wellcome. I am new to pistol reloading.
For those that do not crimp or like me are new to reloading pistol ammo: Here are Some interesting basics about crimping:

I use Lee factory crimp dies and put just a light crimp on my auto loads and a solid crimp on my revolver loads. The Lee factory crimp is a compression crimp, not a roll crimp for those who may not know. It also sleeves the length of the case to assure conformity. Auto loaders index on the case mouth and it is very true that you should never roll crimp them which is in fact rather dangerous. Revolver loads need to be crimped and either a roll crimp or a compression crimp are suitable. The crimp on a revolver case creates a slight pressure increase prior to the bullet beginning to move which aids in thorough ignition for some powders and also a faster jump of the bullet into the forcing cone.
