[QUOTE="rcoody, post: 1099377, member: 91090"] wish I had gotten the headspaced bolt. Ok my new Krieger varmatch 26" .223 match has failed the go gauge test. I have tried 3 different bolts and no love. I know you match the bolt to the barrel but I don't have a bin full of them any recommendations? Or it goes back tomorrow and I send the upper to Krieger let them do the whole thing. Would have done that to start with but I won't have it for a year if Krieger does it. yep we do some pretty nutty things chasing that last little bit of accuracy. yesterday I spent the whole day loading and brass prep for my new AR that I am sending back tomorrow. I do crazy stuff. I like the inside of my cases clean. I use ultrasonic, dry them in my gas oven overnight and then put them in a clean tumbler to polish the brass back up. I weigh my powder charges to 0.02gr. Really helped actually. my vertical is gone and my SD's are in the low single digits used to weigh cases but it is just too hard to keep the separated. Now I just throw away heavy and light ones. Only use Lapua brass so there isn't much culling. I use a forster coax and all forster match dies so my runout is not really bad to start with. but when I want to shoot really accurately I check my runout on finished rounds and cull all those with more than 0.002 on my forster case inspector. and I do lap the receiver face. Fact is that is how I time my barrel nut torque and gas tube. This last one barrel nut had a half hole. Split it perfect. Lapped twice and had perfect alignment with 40# of barrel nut torque. Too bad it was for nothing I am bummed But there is a bright spot. I do have one of Roberts 6mmAR turbo 40's on order. Maybe that will get the 5 five shot groups. [/QUOTE]
