I checked all the dimensions on my new 6.5 Grendel Monster bolt and the measurements are spot on. I used a Hornady tool to measure the cartridge overall length. I have measured seven previous 6.5 Grendel barrels with the same bullets and my measurements of my 12 Group Buy is gtg. The measurements of the 12 GB barrel were almost exactly the same as my Shilen 6.5 Grendel barrel. I just need to get my upper assembled. I pretty much have put this project on hold because of the panic buying and family obligations. Ive debated on pulling my 12 PSA Nitride barrel and trying my GB but I think Ill just wait a few months till I have more time.
