Trim 460 S&W Brass or Don't Bother?

[sparkyv]

I'm not new to reloading, but am fairly new to loading for the 460 S&W Magnum. I by no means am an expert, nor do I already know it all; I continue to learn in almost every reloading session. I have noticed that my 460 brass is starting to exceed the case OAL of 1.800”. I don't recall ever exceeding case OAL for any other handgun brass I shoot, thus my question. Note that I use the Lee collet crimp die for the 460. Is there any need to trim the over-length 460 brass? I'm pretty sure the collet style crimp die mitigates the need to trim regardless if the projectiles have a crimp groove, but I'm inquiring for confirmation / reassurance.

Case length really doesn't matter as long as it's consistent( for consistent crimp). That's why I trim my .460 once, either when it loaded the first time or once fired from the factory.

Difference is .010" case maximum lenght to chamber length. At a working pressure of 65,000 PSI. I would follow the general rules of reloading. Trim when case length exceeds maximum.

But i dont own one.
