I'm planning to get a neck-sizing die for my .300 WM, but am kind of at a loss on which way to go. I've already got a set of the Lee RGB dies and a factory crimp die. I'm debating on whether I should just get the Lee Collet die set and end up with an extra seater die and shellholder, or the deluxe Lee set and have the same extras plus another full length, or if I should get (for about the same cost) an RCBS neck sizer or a Redding Neck sizer (which, by the way, what's the difference in all the serieses they have?). Any suggestions?

I see no need to duplicate dies you have and are satisfied with. So I would get a good neck sizing die. Redding is my choice. But most die makers will sell you just a neck sizing die.

If you really want to fiddle with neck sizing I'd say get one of the bushing neck sizing dies.

That said, I've gotten outstanding accuracy with fl sizing dies. I can't see having a zero tollerance case in a hunting rifle. I'd personally invest my $ into a quality seating die like Forster offers.

Hey catfish

You can buy only the Lee Collet Neck Sizer here

The Lee Collet is different from any other kind of neck sizer and once you use one you will soon have one in every caliber. No expander ball and thus no lube in the neck. Get a Redding Body Die

and you can use the Lee Collet to just neck size or push the shoulder back with the Redding Body Die if you need to.

Still no lube in the neck!

I would get the Lee die set that has the full length sizing die and the collet die. I like using no lube with the collet die; so much less of a mess.

Sell the dies you don't want on eBay.

I wish I could afford the Forster seater die...hell...I wish I could afford to just get all Forster. I've had pretty good luck so far w/ the Lee seater (measuring with a comp). I'm not a high volume reloader, so I don't mind taking the little bit of extra time to measure each round or every few rounds to make sure it's on (I use a comparator).

P.S. Don't go into the concentricity, run-out, etc. please...I done read enough on that and know I wanna make sure it's all good, but the gizmos are too pricey for my budget right now.
