This is on the .264 LBC barrrel page. You have a Grendel Type 1 and type 2.  Lots of Vendors are selling the Type 2 bolts and BCGs. I purchased my Type 1 from Yong Mfg I am pleased with it. It looks to be a very sturdy bolt.

 

"We originally made rifles with the standard head spacing (.125”) which we called type 1 and a second head spacing (.135”) only for the original Grendel which we called type II. Given the demand for standardization and lack of sales the type II head spacing has been dropped for 2017.

 

The problem is solved. The FP was too long. It now runs the way it should..

A 7.62 bolt is a type 11. That's what you want for the 264 lbc.

I use one of those in my 243 LBC that has the same head space as the 364 LBC.

Yep. . Had a bucket of Vita-Grow in the room I was moving and it spilled on my barrel.  It grew 0.1 " just like those tomatoes in the ad.

Greg,

 

I think you've been sipping the VitaGrow.  By BHW's convention, the Type I bolt has a .125" face depth (7.62x39 and some 264 LBC's). The Type II has a .135" face depth (6.5 Grendel, some .264 LBC's and the Beowulf). 

 

If the bolt face depth is .125", then the bolt should be 2.80" to use a standard firing pin. If the bolt measures 2.81", a longer, non-standard firing pin is needed to avoid light strikes.

 

If the bolt face depth is .135", then the bolt should be 2.810" to use a standard firing pin. If the bolt is 2.80", then you need a shorter, non-standard FP in order to avoid potential primer piercings.

I think you still missed the mark there, Greg.

 

The 7.62 bolt is the BHW type 1. (Not the Type 2/II/11/XI).
