Re: Case blackening at the neck
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: V-hunter</div><div class="ubbcode-body"> it does not happen on the first firing of new brass which is full length sized using a standard 308 full length sizing die <span style="font-weight: bold">then expanded on an expander mandrel, neck turned and sized back down with a redding 335 type S neck bushing die</span>. On every other firing the powder residue travels down 3/4 of the shoulder of the fired cases. Accuracy is not an issue the gun is shooting very well. I did not have this issue on the original factory barrel, by the way the rifle is a Savage model 12 F/TR.
Annealing the brass did rectify the problem but this is a timely process and I would prefer to prevent this from happening rather than having to deal with the problem of annealing all my new once fired brass..

Why would you expand, then turn, then size again a neck?
And yet annealing is time consuming......
