If I'm not going to take the time to neck turn my brass is it better to seat touching the lands, or would I get better performance jumping them?
I don't neck turn, how should I seat?

It depends on the bullet you are going to use. Tangent ogive bullets "usually" like to be jumped. Secant ogive bullets "usually" shoot best being jammed.

neck turning has nothing to do with seating. You could say neck turning effects case neck expansion or neck turning effects neck tension.
you should do a seating depth test to determine what COAL works for you

Re: I don't neck turn, how should I seat?
I was thinking that if the neck is not holding the bullet perfectly inline with the barrel, would jamming the bullet into the lands orient it more properly before firing, or would letting the bullet to jump allow it to align itself?
I would assume one method HAS to allow non-concentric rounds to align themselves more effectively than the other? Am I right?
I'm getting outstanding accuracy out of my handloads, but whenever I chamfer the neck some of my brass is very clearly thicker on one side. Maybe I should just leave it - but it just doesn't look right.
x-ring; This was with secant rounds.

You need to invest in some tools, so you know for sure.
You're just guessing at things.
A crooked bullet can still be jammed, but still enter the bore cock-eyed.
If you're shooting a factory barrel, neck turning might not pay dividends, but getting some tools that show you 'runout', neck wall thickness and/or where you are relative to the lands, will.
Some feel that by neck turning, even for factory barrels, you uniform the thickness of the neck walls, thereby eliminating any thin spots, that are prone to creating, or starting, these splits.
I don't know if I entirely buy into this theory, since thin is still thin and now one can get neck splits at every point around the circumference of the neck, but it's food for thought. My degree is in English Literature/Communications, not Metalurgy.

Re: I don't neck turn, how should I seat?
Like mallard said. Bullet jump and outside neck consistency are different variables. Work up the load with the right powder, then play with oal, then work on concentricity benefits of neck turning.
