i threw the primer out ...just took the bolt out to measure it and a damn primer come out...weird i think what are possibilities? gun was built by a local place here but well known on the interweb http://www.jsesurplus.com the barrel is a double star i think as it says something like 6.5 grendel DSG not sure about the rest of the upper....he had it made when i got there...shoots good i think other than a couple troubles in the first 50 shots with no fires...but i forgot to lube it ...they didnt and i forgot before first outing...tnhis primer had to come from the second shooting with it only ran 20 shots through it....

Leads to questions about which bolt was mated to which barrel. Primers come out because of pressure issues, which most commonly happen with hand loaded, hot ammo, or because of head space issues. Head space issues in the Grendel most commonly happen when the barrel and bolt aren't properly matched. This happens when a Grendel bolt is used with barrel headspaced for use with a 7.62 bolt or, less commonly, vice versa. Factory ammo seldom is loaded hot enough to cause an issue, especially Wolf ammo.

You need to find the piece of brass that goes with that primer!

Pictures of the case heads on a few of the fired rounds may help to asses some the issues.

man i hope nothing is wrong with my gun...so excited about the thing...let me know what yall think

You are certainly experiencing some over pressure issues with that wolf ammo, put some Factory Hornady through it and then show us some pics.

Is the Wolf ammo "123 SP" or "120 MPT"?

[stokesrj]

Those cases that lost primes were over pressure. It is fairly common to get a loose primer caught in things gumming up the works, that is why the military stakes primers. It is more common that they fall into the lower receiver and eventually jam up the trigger so you might want to look for the other one there. It is less common that they find their way into the bolt control group. I suspect your gun will be fine. They are pretty rugged.
The real question to be answered is why would Wolf Factory loads be over pressure?
Is this a Grendel or LBC, or other?

120mpt....so this is maybe not the gun? i hope not , other wise ill never sleep well tonight ! i will shoot that H stuff this weekend have a box of 123 Amax in the truck ...what tells you its wha t you think it is? trying to learn is all

Actually there is a bit of trouble here. Do you see the little circle and the rectangular notch on the case head? That's not good.

Do you have a set of Dies and a digital or dial calipers yet? If you do, you can re-seat those by .010 (shorter) to relieve the over pressure.

its a grendel factory Wolf gold mpt 120 g. so what about this wolf brass only resin i bought those bullets was for. fourteen a box to get used to rifle and i would have brass to load with hornady later on this year also! i was loading a mag this weekend and found one bullet .mpt stuff. ...is almost a quarter inch shorter than his buddies in the sane box!

[Bwild97]

The 123 SP are too long for the chamber in my gun, but the 120 MPT are fine.

[hill.brandonj]

well i can toss this brass all that wolf stuff .wont bother me .just hoping my gun is not the culprit .is it .according to the photos anyway?

I have only seen that in the 123g SP, So I pulled the projectile and used my sizing die (with out the decapping rod in it) to resize the neck and then reseat the projectile. It was quite a hassle. so I don't buy the 123g SP any more.

Hard to say with out seeing the fired Hornady cases

One of the only real good ways to check headspace is with a set of go & no go guages...Doing a chamber casting would also be helpfull in determining
if you have a tight chamber that may also be giving you high pressure problems...I know the guages can be pricey but, they can also be rented for a
fair price, this would be the most cost effective way to help determine possible headspace Issues...Good luck.

wonder if the shop that built it might have it.. .I'll call them this morning
