where you get mags that accept 2.92 or so OAL ?


The mag's measurements are ASC at 2.289-2.293in or so, C Products at 2.3in and PRI Mags are at 2.305in. I'm using a C products mag which has a nice coating but with a ASC follower. I find the C products follower is not as good quality as the ASC but the C Products mag has a better coating. So i combined the two. ASC sells followers and springs separately so makes it asy to combine with C products shells. I can't find my PRI mag that i have an ASC follower installed in grr!!

so cal, I have to ask what was the purpose of your post. I think many of us already know if you load the grendel up to in excess of 60k psi you can get ALOT more speed out of it


First the purpose of this post is to correct bad information out there such as you while well meaning i'm sure did post.

Second when you load longer leaving more room in the case you can achieve higher velocities without higher pressure. Its like having a larger piece of brass with more room for powder. It does not mean pressure is increased thats a common myth. Read more about it here. LEVER gives 150fps better velocities with the right conditions like what is present in the Grendel II loaded to true mag length.

Here is SAAMI velocities with the 120gr Nosler to compare to my Grendel II velocities. The GII is 200fps faster on some loads and isn't using a bunch more powder to achieve the velocity.

the grendel II was created because liberty/saturn barrels used the wrong reamer and cut their barrels throats too short


No the Grendel II was created by Bill Alexander and Arne Brennan in 2003 and announced at Shot Show in January 2004. Steve Satern had nothing to do with its design in any way at all. He just ordered a different Grendel reamer because he was tired of the newer compound throat causing problems so PTG sent him the original design that does not have the bullet getting stuck issue that is a common problem with the compound throat.

PTG named the original throat the Grendel II and Steve used that name. Be careful of the garbage passed on the Grendel forum its not very accurate sometimes. Some of the "experts" talk out there a$$ a little to much. In this post Arne Brennan the co designer of the Grendel confirms that the Grendel II is simply the original Grendel. In other words the Steve Satern silly conspiracy story is just false.


Here's a list of threads with various barrels with rounds getting stuck in the compound throat. The Grendel II does not have this issue nor does the 264LBC that both have a .120in throat. Only the compound throat has the issue with factory loads getting stuck. As you can see from the links below the problem goes much farther than what Satern had and has now fixed with the Grendel II. The Grendel II and the 264 LBC both use the same length throat with the neck size being a little different. They also both use the proven parallel throat design used by the 6.5 Creedmore, 6.5 lapua, 260 Remington, 6.5 Win Mag etc. It's a proven design that is pretty much standard only the 6.5 Grendel (SAAMI) uses the compound throat which causes problems.

lastly I look at your chrono data from 31.3-31.6 I am seeing a pressure spike I would be concerned about that much increase in speed with that little extra powder charge.


The increase in velocity is actually lower from 31.3 to 31.6 that it was from 31 to 31.3 so no thats not a velocity spike. An increase in velocity of 40fps with a .3gr increase is completely normal. Hope I've cleared some things up for you.

Here's a chamber drawing of the Grendel II dated 2008 but is actually the original Grendel from 2003 and announced at shot show but at the time simply was called the 6.5 Grendel. The compound throat was added years later and has caused all the rounds getting stuck issues in may different barrels but from what i found online the "stuck bullet" syndrome is mostly centered around Alexander Arms but effected Satern as well.
