I run each case through a Forster case gauge. If over max, I trim to minimum. Generally, I trim about every 4th loading. The "Factory crimp die" is very forgiving of minor variations in case length. MINOR!

i do not crimp bottleneck cartridges.

straight wall cases only get a crimp enough to return the case mouth to the original sized diameter.

bullets are held in by friction of the case mouth not the crimp. cleaning the inside of the case mouth of lube is critical to this function.

i use carbide expander balls so i dont have to lube the inside necks.

crimping bottlenecks can easily cause the case mouth to lose tension on the bullet resulting in longer bullet runout or setback due to lack of friction.

needing a heavy crimp on heavy recoil rounds or tube feeds is a myth. if you do crimp be sure your using the correct crimp for the bullet. cannelures are for roll crimping bullets without roll crimps should be taper crimped only.

crimping is the biggest misunderstood myth riddled part of ammunition loading i can think of.

You forgot it include the third and most effective crimp for Bottle necked rifle rounds, The Lee Factory Crimp die. It is not a taper crimp or a roll crimp but a collet type crimp.

The LFCD not only helps secure the bullets (Cannelure or no-cannelure) it improves accuracy in my semi-auto loads.

Here is a little test. Three rifles, three different cartridges, 50 rounds each. All three showed improved accuracy with the use of the LFCD.

I use a Lee FCD on every caliber I reload. They work great. I bought all of them off eBay. I no longer use the crimp ring in the seater dies.
