[QUOTE="bigedp51, post: 1180490, member: 28965"] Reducing the neck diameter from .308 to .243 "increased" the neck thickness variations. And some of the converted 7.62 LC cases ended up with .008 or more neck thickness variations. And as shown below turning the neck does not center the bullet with the case. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/neckcenter_zps94286f86.jpg[/IMG] Using standard LC brass means a lot of sorting through cases looking for more uniform cases that are worth turning. But the link I posted also shows that when neck turning donuts become a problem. There is a reason why competitive shooters spend $1.00 per case for Lapua brass and do nothing to it. Below is a Remington .223 case showing .004 neck thickness variation and this was the average with some at .001 and others at .008 variation.

Bottom line, you can't make a silk purse from a sows ear. [/QUOTE]
