Well, I think turning case necks has it's merit, I personally don't believe it's more important than having powder charge weight errors of " a couple of grains". Are you sure he didn't say TRIMMING the case necks??
I've got some mighty fine shooting rifles that have had their cases loaded several times or more, and have never seen a neck turner. I'm not buying it.
Yes he was talking about trimming! Sorry. I'm a relative newbie and easily confused.

Ah, so! Trimming is a different proposition. Cases must be kept under the max. length in order to avoid a condition in which the bullet gets "stuck" in the case mouth on firing. This can cause high pressures! Cases should all be the same o/a length, as well. But how much effect cases of variable lengths has on accuracy I cannot say, since I've never experimented with this factor to find out.
