Load at the range. Select your brass from the cases that go into the group. keep the rest for sighters. I stay with Laupa .308 WIN and make all my cases from this brass. It's a pain I know. It's a shame we can't just buy better brass.

What are the steps to forming 6mmAI brass from 308? Is it more uniform? I thought one the case was fire formed it fit the chamber and it was ok. Guess not, would the 1-8 twist in my barrel cause it to throw fliers with the light wt bullets? [img]/ubbthreads/images/graemlins/confused.gif[/img]

[/ QUOTE ] I don't know what you mean by a light bullet? The one in eight twist would work with the vary longest bullets in this bore size @ the velo you get with this chambering. However if you are shooting benchrest length bullets in the one in eight......... [img]/ubbthreads/images/graemlins/blush.gif[/img]

3-6bits,
Thanks for all the great info. I hope i can get this thing sorted out before i rechamber it. I spent alot on the the dies,seaters,brass,and bullets to stop now. But All my other ackleys have been so $&^%* accurate and easy. [img]/ubbthreads/images/graemlins/mad.gif[/img] I bought a clymer gauge for 6mm ackley 40 degree, and when I chamber the gauge it is so tight I barely can get the bolt closed. Is this too tight? I know there is supposed to be a crush fit, but this seems a bit much. I lube my lugs good and take out the firing pin and ejector. I do all my own smithing and I have wondered if this could be a problem. [img]/ubbthreads/images/graemlins/confused.gif[/img] [img]/ubbthreads/images/graemlins/confused.gif[/img] Any thoughts?

My gun shoots 68Gr Barts and 75 gr Vmaxes into one large hole...sometimes [img]/ubbthreads/images/graemlins/frown.gif[/img] I was asking if the fast twist (overstabalizing the bullet) would cause the intermuittant flyer? Again, how do yoou form the brass from 308 ??
Thanks
