260 Dies

[neeltburn]

Tell me about match grade 260 dies? Parts are going to the smith soon. Looking at RCBS Gold Match Dies but they are a bushing die and I have never used a bushing die. Is the process any different? I use RCBS Competition Dies in my 308 and wanted to use them as well however RCBS does not make them in 260. Im not stuck on RCBS just wondered what others are running.

Redding Type S FL die, add a Floating Carbide Sizing ball, a .290 bushing for Rem brass, Redding Competition Seating die, that combination is what I use and recommend.

+1 for 427, I run the same setup, and have had no issues with runout, J

Where do you get the floating carbide sizing ball? How do you determine the bushing size? I use lapua brass in my .260... Sorry I know its not my thread im just wondering.

I have never used Lapua 260 Brass, but a .290 bushing works great with Rem and reformed Win 7-08 brass, the expander barely touches on the way out, or not at all(not at all tells me its time to anneal)the floating carbide expander is .002 smaller than a bullet, measure a loaded round, subtract .002 and that will get you close to the correct size bushing, or measure the neck thickness in four places, the average times 2 plus .264, subtract how much neck tension you want for the exact bushing to buy.

The carbide ball is a redding accessory. Don't use it if it opens the mouth wider than your desired neck diameter. Determine your bushing size by loading a bullet into a fully chamfered and deburred case, measure the diameter of the neck, then subtract .001 or .002; I usually have several bushings handy for different brass. Sometimes my measurements are in between, so I will get .0015 neck tension.

Why the FL sizer and not the Neck sizer? And what is the difference between the type S and non S?

My 2 cents...

I run the following setup:
Redding Micrometer Seater die
Redding Body die
Lee Collet neck die (I really like the collet dies...I use them in 260 and 308 and my ammo will out-shoot me all day long). The Redding bushing dies are nice too, you'll get good results with either die.

Also, if you pick up Lapua brass, it can be a pain the first time you load it. You may need to run the brass through either a die with an expander ball, or the Lee Collet die with some lube on the inside of the neck...the necks on new 260 Lapua brass are extremely tight. I made a thread about this not too long ago and a number of people chimed in with the same experience. If you don't want to bother with having to lube the inside of your new brass, check out the Sinclair dies with an oversized mandrel...you can get carbide mandrels to slightly oversize the neck, then use a neck die to bring it back to spec. I literally couldn't run the Lapua brass into a FL Redding die or Lee Collet die without using lube on the necks they were so damn tight.

I have read a lot of stories where Lapua Brass has to have the necks turned down for match cambers as the case wall at the neck is thicker than Remington brass. Do bushing dies correct this? I will look into the Redding dies, also is it the same bushing for full length and neck sizing dies?

Lee Collet neck die

 

[scudzuki]

Redding S type FL die for neck bumping every 4 firings (after annealing) with a properly sized bushing to not require an expander (currently a .291 after neck turning my Lapua brass).
Lee Collet die for neck sizing the other 3 firings.
Redding micrometer seating die.

In my experience, f\l sizing with minimal shoulder bump is better than neck sizing. Neck sizing alone has never yielded any advantage for me. The new school seems to collaborate with this too. The type s die is the bushing die. The non type s gives you a whole lot of neck tension that you might not want.

If you need to turn necks for a tight chamber, then that is what you need to do. Has nothing to do with bushings

Bushing dies enable you to try different strategies, like resizing the neck just enough that an expander will barely open it up, which works the brass less, or resizing right to size with the bushing (what I do). You can also experiment with neck tension fairly easily.
I experimented once with a Lee die and discovered that expanding the neck introduced all sorts of runout. I removed the expander and FL resized a case then measured the neck size and runout, and then repeated with the expander in place. Of course Lee dies (and most likely all off the shelf solid FL dies) must work with all brass (with varying case wall dimensions), so the neck is initially closed up way smaller than it needs to be (with most brass) then opened way up again, around .008" in the '08 5.56 LC brass I was using. The runout went from .0025" without the expander to .007" with the expander.

Bushing dies do not change wall thickness, but having one enables you to fully take advantage of neck turning.

Another one for Lee collet die, Redding body die and Redding micrometer competition seater.

What size bushings to re-size LC 7.62 brass to 260? I have a ton of once fired LC 308 and PMC 308 and my .260 is about a month away from the gunsmith being done.
