Well...................I see RCBS offers a 25cal pilot for the Trim Pro - don't see why it wouldn't work. But then again, I don't own any RCBS equipment, so I can't say for sure. My Lyman Universal trimmer has a pilot for .25ACP I know.

But I have to ask..................... why do you want or need to trim them?? I'm assuming you're using a them in a semi-auto pistol..................if so, the gun would headspace on the case mouth and if you trim them too much, you may get failures to fire and at least failure to eject properly.

I've never HAD to trim any pistol case (revolver or semi-auto) except when the mouth got chewed up from use..............or more accurately, OVERuse! Typically, pistol cases are a little on the short side anyway - and once you start trimming them, you don't have much left to work with.
