Yea, it's a potato stake so far. The short throat I think was caused by the chamber not centered with the bore and I was getting a distance to land length of 2.212. The throat reamer was just nicking a couple of lands and I opened it up to 2.261. Test bullets were still showing scratch marks from the lands so i reamed it out to 2.288 where the reamer felt like it was getting a even cut and chips showed. Bullets are not jamming in the lands now.
First time out with Federal 120G HP the first shot had a pierced primer and the scrap from that was stuck in the firing pin hole. Had a lot of failure to fires after that. Firing pin gauged out later as being .015" too long. Groups were minute of hubcap.
This upper out of the box was unsafe to fire. Fixed the firing pin and cleaned up the throat so we'll see how this poop stick does the second time out.
