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.

Brass should be trimmed to specifications. If the cases are different lengths, then your crimps will not be consistent. If too long, then they may not chamber or it may cause a rise in pressures. The beauty of straight wall cartridges is that they don’t tend to stretch during firing. You may not have to worry about it. But do check.

Busted...but not posted everywhere, Rule3...only in three forums, obviously the three in which we both frequent. Actually, I'm seeing consistent responses, but most are not from 460 shooters. It's just that I've never had to trim pistol brass before.
