Can anyone tell me what Hornady has for Minimum and Maximum brass length for 6.5 PRC, what they recommended trim length? I cannot find what I am looking for and my Hornady Reloading manual doesn't have the PRC.

The book is a great start
Have you fired it yet? Your chamber length can have something to do with how you trim - if you have a short chamber - you may see signs of deformity around the rim of the mouth...if so, measure back to a thou below the low point and use that as your trim length.
If not and you are just looking to make them uniform, measure maybe 20 pieces of brass, find the shortest one and trim all of them to that length.

I have already fired them and some had been reloaded for several sessions. Just wanted to get them all to the same starting point, some measures long and others were only a few thousand different than minimum. This is all Factory Hornady rounds I had used to help break in barrel.
Get yourself a case trimmer if you don't already have one. Trim to factory trim length. Work from that for the life of the cases.

Yes, I have a case trimmer, an old Power Lyman case trimmer, works good.
i trim @ 2.020" instead of @ 2.015". just my preference.

I trim my 6.5prc to 2.020", but when I'm not certain on a trim to length I reference SAAMI spec drawings, as well as comparing between by "bibles". I also bought a bore scope not long ago and actually took some of my fired brass that measures at max cartridge length and chambered it in the gun and looked to see if there is any gap between the cartridge end and the end of the chamber throat before the freebore. So far in my 243win and 6.8spc, I have found that I can go 2 or sometime 3 firings before I have to trim back to my trim to length. I haven't reloaded my prc enough yet to check, but what did load I trimmed first.
He is right. I trim mine so there is a gap, but only a small one, and I also make sure I am getting adequate neck expansion at that trim length. If you have those two, no carbon rings, or at least way less, and a longer neck to seat bullets.
I still neck size most brass, so I only have to trim about every 3 rounds. I would trim every time if I had to, to get the other benefits.
