beastep Wrote:Im doing load development on a BCA 20" non 5R barrel my girlfriend got me for Christmas and after a few problems and a lot of troubleshooting I finally figured out the length of the throat on this barrel is quite short. Short enough Im getting into the lands on everything loaded to book at 2.245 and also factory loaded Hornady 123 SST. I thought it was just my barrel but a buddy came by yesterday to bed his barrel and we checked his throat length and it is just as short as mine. Im having to load way short, around the 2.20 mark, to get them off the lands on my barrel. His is a Saturn Liberty SS 18" 5R barrel. Is this common for a Grendel? I have a hard time wrapping my head around the fact these chambers are cut to a spec that allows factory loads to get buried in the lands.

By the way, which bullet are you using for your handloads?
