6.5 PRC brass

Young-gun · #1 09-23-2022, 05:14 PM

Well was doing load development for brothers browning. Turns out it has head space issue! Wrecked 100pc of gunwerks brass trashed due to head separation. Anyone have or know where I can get some. At this point I don’t care what brand!
Thanks

Gunwerks brass is made by adg and there seems to be an issue with them and under sizing brass. Not so much of a head space issue but the brass expands at the webbing a ton and you get clickers. And then case head separations

Possibly. I full length size everything. My tikka running hot loads doesn’t do anything to them. Every round through his has a definitive ring, and it’s worse inside case. Gun is going to smith to have Go/No Go gauge ran into it.

Measure the .200” line on new brass and fired brass
My 300 Norma adg brass grew a lot

Watch the one on clickers

For sure it’s a brass/sizing issue

marky_mark · #8 09-23-2022, 06:31 PM

Prc’s are bad for clickers

marky_mark · #9 09-23-2022, 06:38 PM

Whidden dies and adg brass equals clickers
That’s what I’m learning lol

I have to call Brent tomorrow too and check for 300 Norma brass

Not just Whidden dies from what I've read, it's most die brands for the 6.5 PRC.
To the OP, are you using the same Whidden die for sizing brass for your Tikka?

Case head separation can also be caused from over sizing, bumping the shoulders too much. I'm not saying this is the particular issue here, but it is a common effect.

Redding competition dies. Got a headspace measuring device on the way. Possibly my measuring skills are off. But this is first time I have ever had this happen.

If you have any new brass measure them at the same point, the mark on the fired case and see what the difference in size is
You could also put the empty fired brass in the chamber and try and cycle it
Click at the top = bad

There's Lapua 6.5 PRC for SALE on CGN ! $300 per 100 ! RJ

DLab · #17 09-24-2022, 08:18 AM

I would also offer an "in general" suggestion, I usually don't fire form all 100 brass to start, I will light load fire form 25-30 and run them for load development and use, especially a hunting round.
When those get enough firings, they get stored and I start on a new batch.
Lapua, ADG, Peterson ,etc. is pricey brass, one or two expensive lessons got me to use this method.

New brass gets a fire form load 1.5-2 grains under max book load for initial forming.

Fired brass at mark is 0.532
New unfired 0.530
Resized (once fired) 0.530

New neck sized lapua brass.

Gun has been tested with go/no go gauges, chamber within spec. Got n is headed to browning now, thinking it’s alignment issue (lines show up on same side of case every time).

Going to say no it isn’t.
I have 300 and 6.5 Prc reamers and have spun up quite a few barrels with them. And have never had brass that looked like this.
Only issue is if you run them hard you will get some clickers.
I also have the new “Aw2” reamers in both 6.5 and 300prc
Done a few in these as well. I haven’t seen that much difference.
And it looks like the OP has a factory chamber. Looks like there are issues with that. I have seen some unbelievable crappy factory “chamber “ jobs.
No idea how they can get things that screwed up

catnthehat · #23 09-28-2022, 09:56 PM

I have to agree, it is a rifle problem not a brass problem, especially since your Tikka does not exibit brass doing the same thing.

Seems like a lot of people are having the same problems with Chamber issues

It's not just the 6.5 PRC.
Lately at our range we have seen issues with various brands of factory ammo and factory rifles not chambering , and there is no pattern to it except for three three types of ammo - 270Win, 308 Win, and 6.5 Creedmoor.
The rifles were Savages and Tikkas.
