I just received my newly built rifle and am having issues.
Defiance Deviant Ultralight action
26" Proof Sendero Light CF barrel
6.5 Gap reamer .120 FB 296 neck
Manners EH6-A stock
Jewel trigger
PTG bottom metal
Wyatts mag box.
Bertram 7mm SAUM Brass necked down and turned to .014
Hornady 143 ELD X
I will post pics below but when I got this I had some strange looking substance in the barrel all the way down the tube. It looked like rust or copper fowling to an extreme degree. I spent 3 hours cleaning it out before the patches finally had no blue on them. I then used a little JB Bore paste and was still unable to get the streaks out. I talked to the Smith and we agreed I should try the Tubbs 50 bullet Final finish system to fire lap the barrel and try to get it out while fire forming my brass. I noticed I had high pressure signs (extractor mark and flatened primers) even as low as 58 grains of H1000. I finished the 50 round cycle cleaning to bare metal every 3 rounds with copper solvent. I decided to try HBN and coated 200 143 ELD's and proceeded to load them. I am getting way too much neck tension when loading these. It is leaving a very distinct ring on the bullet and seating depth is inconsistent. I tried wiping them off completely and that helped a little but now seating is very easy on some but still too tight on other bullets. I did not have any issues with the Berger 130 VLD's that were coated in my 6.5 Creedmoor. It makes me wonder if it will be accurate at all with such variability in seating pressure. Is it something to do with Hornady bullets and HBN? I shot the HBN loads at 57.5 grains of H1000 and I still have some slight pressure signs and a slightly stiff bolt but mainly after the first shot. I was hoping after 25 rounds of HBN loads without cleaning the barrel it would be seasoned and pressure would go down. I also tried a few fire formed pieces of brass after bumping the shoulder .002 with no difference in pressure. This was all done in my back yard with a suppressor at 20 yards as I live about 50 feet from the city limits. I am going to take it out tomorrow and shoot it over the lab radar and see what kind of velocities I am getting but I am now afraid to go over 57.5 grains. Any ideas on what the issue could be or what I should look for?
Thanks, Al
