[QUOTE="carverelli, post: 507581, member: 4794"] you may not remember Kirby, but we had several email conversations around 2002. Before you started your smithshop. Dan Olsen did the work as I believe he helped you with one of your rifles, and you recommended him to me. THe first chamber he cut was throated really long and it was MY belief at the time that I had to nestle the 107mk against the rifling, and I had to seat them too far out. I sent the barreled action back to him and he cut some of the barrel down and rechambered. My OAL is right at 3" for the smk's. I made up some more ammo this afternoon, and will attempt to shoot early before work this week if conditions are favorable. Some of the primer pockets are started to loosen up on my old 284 WIN brass, but I've got 4-5 firings out of them. Not sure if he meant too, but when Olsen cut the chamber he left a small machining mark about 1/8" long right below the shoulder. I can count the marks on my brass to see how many times they've been fired. Several years ago I bought some Norma 6.5 x284 brass thinking maybe it was better than the Winchester stuff. It was easier forming down to 6mm. I have redding bushing dies and a small base die(that i used today as the bolt was getting tight on some brass) my chamber neck is .268 if memory serves me and the bushing im using is .263 It probably springs back .001 or .0015 and then .002 neck tension has .0015 or so left to let the bullet go. Runout on most fireformed loaded rounds are .002- .004 and new unfired formed load can be as high as .01 like you said though, I'm getting close to satisfied with the rifle because they more load development I do the less barre/ accuracy I have left to enjoy. Last weeks shooting conditions were far from ideal, and I dont have a lot of experience doping wind and/or mirage. Bullet holes at 300 yards were touching, then as the length increased the groups did also. I am working about 45 minutes from Wenatchee WA and I hear there are Rockchuck opportunities around. But getting someone to divulge their honey hole may tax my people skills. BTW, thanks for responding and getting my hooked on the LR bug.lol [/QUOTE]
