Grendel II chamber was developed by
Arne Brennan and
Bill Alexander in 2003 and announced at Shot in January in 2004. At the time it was simply called the 6.5 Grendel. With Satern and other barrel makers suffering from the bullet stuck syndrome common with the compound throat and after a call from Steve Satern PTG dusted off the old print for the original Grendel and called it the Grendel II. In other words the Grendel II is Orginal Grendel (OG). That fixed the problem and so far seems to shot with higher velocities. At least with my hand loads. Factory SST is about the same at 2624fps. The 65 Grendel forum reacted with shrill screams of foul play forwarding the false story that Satern had a bad reamer and was covering up for that and it was some kind of evil plot between Steve Satern and Dave Kiff. In a hilarious twist of fate it turned out there own barrel buy of lilja barrels were "out of spec"with a custom throat they ordered adding to the conspiracy hysteria. They of course I'm sure received just what they ordered everyone now wants to avoid the
stuck bullet syndrome that has been reported on JT barrels, Alexander Arms barrels, Liberty barrels, McGowan an others when using the "in spec" throat. Of course the problem is never the spec it's those bad reamers everyone seems to be getting (conspiracy). Paul (LRRPF52) and his spin machine have had a rough couple months trying to put the blame anywhere but the obvious "spec". Barel manufactures are trapped if they use a "in spec" throat they could have stuck bullets and angry customers but if they change the troat they have offended the "Grendel Cult". Precision Arms has lengthed there throat to avoid the stuck bullet syndrom but kept the compound throat which seems to have satified the cult." Poor Lilja just wanted happy customers but stepped in it.
