Any thoughts on beveling case mouths?

[Kappy]

Does anyone have any thoughts on beveling the inside of the case mouth? I'm trying for precision in an AR. I understand that beveling will help with seating the bullet, but I'm already using a competition seater, so that shouldn't be an issue, right? I just got a new trimmer which cuts the case pretty much perfectly with nothing in the neck.

Basically... I just want to eliminate the step because it's a pain in the *** and takes time which I don't want to spend if it isn't doing any good.

This typically is called "chamfering" and is a very good practice for match grade ammo and even for plinking rounds because it lets the bullet seat more gently and without insult to it's jacket :-)

Especially important as part of the case trimming process as it fixes the "square and ragged" case mouth syndrome most trimmers leave behind.

I agree. I also given the case mouth a good brushing with a bore brush as a final step before loading.
