6.5 Grendel Case trimming

I found that with Hornady cases you almost have to trim after every firing.. I full length size as it's for an ar.. I've switched to starline brass.. and can honestly say that brass hasn't needed but a light trim.. in fact I just v finished wth my 6th firing and it's still good. So onto the 7th it goes. As far as primer pockets, they are all good. But definitely can feel them growing on me.

I'm currently in the process of seeing how long I can go without needing to trim for my ARs. It doesn't seem to be growing much on me. I use nothing but Hornady brass and I have some with a few firings on them like +6. I don't typically hot rod things though.

I have yet to see a Hornady case go past 1.530" case length. Most don't go much past 1.525".

The only brass I've seen go past 1.530" is older PPU, which is really soft with Large Rifle Primers.

Some of my once fired Hornady 6.5 Grendel cases were a little over 1.520”. I checked several through my Lyman EZ gauge MSR,and measured them with mic.Then,I set up my Wilson trimmer to trim them all to 1.510”
Reloading is easier when all my cases are uniform in size.My rifle cycles better too.I check cases with my EZ gauge after firing to see what’s going on.But,I trim them all.Then chamfer/deburr.

I emailed RCBS to see if an X die in 6.5 Grendel is available. I've been very happy with the ones feeding my .223 ARs and the 7.62x51 gas guns. Trim cases once, set die and done.

It is amazing how people get different results for what should be the same thing. I'll throw in something slightly more different. 100% of my 6.5 Grendel brass is Hornady. I trim with a Little Crow trimmer set to max case length. From new brass to some past it's 8th firing I get almost zero case stretch. Yet there is always about 1 case in 20 that needs some trimming. No matter what (also true for my 5.56, 300 BLK and 277 WLV) a case stretches once in a while while most of the others do not.

BTW... since getting the Little Crow trimmer I rarely measure case length. After the cases are resized (shoulders set back and extra .002 to .003") they get run through the trimmer and into the tumbler. I've been meaning to ask for thoughts about this and this is a good time.

Thank you
