Which dies for least runout?

[Supergyro]

I'm looking to minimize runout caused by the dies. I know brass work is a big part of it, but I'm focusing on the hardware end of things here.

Should I go with the Lee Collet neck sizer and a body die for the bump, or a Redding S fl bushing die?

Also, since I'm seating VLDs should I get a VLD specific seating die?

Thanks in advance for your suggestions.

Use Wilson.

Redding and if you shoot VLD's their mic for the VLD works great..

Low runout is more a function of technique and paying attention to detail than die selection. A runout gage used at each process step will tell you where you need to change dies. That being said, I like the Forster seat dies best. I do what you stated with my 25-06 ... Lee Collect Neck Die and Redding Body Die. The Lee die works great providing the brass is concentric to start with. It won't remove problems but it won't exaggerate them either. The body die doesn't do anything the FL sizing die can't do. For FL sizing I've found I'm partial to Lyman and Redding.

Forgot to add, I use the Forster Concentricity Gage. It works really well on large cases but tiny ones like my 221 Fireball it's a pain to use.

Another vote for Wilson straight line, chamber type seating dies. You can even have a blank one cut with the same reamer used on your barrel, because they are not hardened. What's not to like about that? BB

PS then your concentricity gauge will stay on the shelf, gathering dust.

Wilson seating dies for 5.56MM, 7.62MM, & .30 Cal. here also.

Here's my 6.5-47 Lapua after I'm done loading using Wilson Neck sizer and seater.

We'll see about that, just ordered a Forster Ultra Micrometer seating die in 6XC for my 6 Creed, My Hornady seater usually doesn't get past .003" runout, many times the dial doesn't hardly move. Hopefully the Forster is even better.

Using a good quality run out gauge like a Sinclair will help you figure out if your chamber job sucks, which there is only one fix, or if your technique needs to change, 99% of dies will produce straight rounds, the end user MUST adjust his/her technique/process to make straight ammo, FWIW if less than .001 or less run out your goal neck turning is required, or using not as consistent using a mandrel or mandrel die(Lee Collet Die) to size your necks to final size along with Annealing every time.
