I have been loading for my new 257 bob, using Win brass and I am finding that some of the cases you can see that the neck wall thickness ( looking down into the case at the neck opening) is not consistant all the way around , which I think incresses bullet run out.What do you guys do to remedy this?
Need some good brass........ or something

brass...
Loaded up 30 rounds, I rolled the rounds on a piece of glass and about half you could see the bullet wobbled as it rolled. If the neck thickness was thinner on one side what happens when case neck is sized by the expander in the die? Had one case that I could see the difference. I am running new cases throgh a full sizing die, before sizing I debur and trim the new cases and again after sizing.

Get yourself a Forster case trimmer with the neck turning attachment and turn them. Don't forget to get the collet & neck turning pilot. You could also get a comp bullet seater from forster or redding for more precise bullet seating. Sinclair Intl. ships to canada.
Where is the wobble at the nose of the bullet? Or can you see the wobble at the case neck. If it is at the nose of the bullet it sounds more like a seating die problem (adjustment) than a brass problem. Again carefully measure the necks with a caliper to see if the is a huge difference.
brass .... my screwup
I think I found part of the problem, had the die screwed in to far, used a felt marker on the shoulder and sized it and I can see that the shoulder was being bumped back. Adjusted die and wobble goes away. Now what do I do with 30 rounds of wobbly ammo? I will try to resize and just seat a bullet in the case and see if the die will straigthen the neck out.

Something that all new reloaders need to be aware of.........if you can't reload consistent, functional, good looking ammo with currently available, popular, and repeatedly tested reloading equipment.............ask what you are doing wrong before you attempt to blame the equipment or components.
Over the years, when I've noticed that something wasn't right, it's always gone back to what have I done wrong.

What to do with 30 rounds? Try shooting them to sight in your rifle, and to practice with. That would include some standing and other positions.
You could pull the bullets, but then you would have to resize, etc. Faster and more productive for shooting purposes to use the ammunition as ammunition.

Go out and buy a kinetic puller. They are cheap and will pull most bullets easily. They run around $30 depending on where you get it. If you want to go a bit further, Forrester and RCBS make collet pullers but you will need a special collet for each diameter. The kinetic pullers do a lot less damage and don't distort the bullets. In most cases, the collet style won't either, they just take longer and require more time to pull the bullets.
brass.....
I have a hammer type bullet puller, resized the wobble cases, reseated bullets, still a wobble, die will not correct the bent necks, some of the rounds are not to bad, will use them as foulers then see if the cases have been fireformed back straight, I will garbage about 12, always something to learn when you reload.

Yep. Shoot them. Might as well see with your own eyes, how much, or how little, difference the wobble makes. Even if they don't shoot accurately, they will fireform out to fit the chamber anyway.
Fer s**ts and giggles, it's a grand exercise !
Most guys can't shoot well enough to justify some of the nit-picky stuff they think needs to be done when reloading. Some do, though.
Try them out. It may be a real eye opener, either by making a huge difference, or almost none.
