[QUOTE="BobTWB, post: 1511326, member: 105349"] I decided I’d better finish the story in case someone else runs into the same problems I had. I ended up buying a no-go gage and the bolt closed on it, even without removing the ejector. Noreen then had me send in the gun. They ended up replacing the barrel, the barrel extension, gas block, bolt, extractor and ejector. After the gun was returned, the new chamber (correctly) didn’t close on the no-go gage. I was also able to turn the new gas block off, so I could just manually extract the brass, which was great, since the brass was previously getting quite banged up on ejection. Rocky Mountain bullets has been continuously out of the 300 grain aluminum tip projectile my friend wanted me to use, so I tried various alternatives, settling on the 280 grain Barnes LRX. Fired Norma brass in the new chamber had a volume of 116.8 grains of water. I loaded the Barnes LRX at .050 off the lands which was a COAL of 3.715”. I found a load of Retumbo which was 0.8 grains over Barnes’ max, but below max pressure adjusting QuickLoad for the case volume and longer cartridge length. It shot a 100 yard 0.8 inch 3 shot group at about 2775 FPS from the 26 inch barrel. At that point, I ran out of time with the gun and sent it back to the owner along with samples of the same load at COAL’s .030 and .070 off the lands. He’s going to shoot the test loads then I’ll make him a bunch of which ever shoots best. Overall, Noreen did the right thing and the gun is shooting pretty well now. It was an interesting and educational exercise for me as well. [/QUOTE]
