260AI reloading equipment?

Hi guys,

I want to know what exactly I need to reload 260AI. I already have the following as I currently reload for standard 260 Remington:
--Redding Competition seating die;
--Redding Neck sizing die,non bushing);

I understand the methodology of fire-forming brass and how the new Ackley-cartridge dimensions are formed. I am curious if I can use my current equipment to neck size and seat bullets to the AI fire-formed brass. I have done a search & found a post where the Lee Collett neck sizing die was recommended. Do I need to go this route or can I just use my Redding neck sizer?

I understand that my current Redding seating die will work fine for the Ackley loads. Neck sizing is what has me a little confused...

At some point I'll probably buy a FL sizing die but I don't want to go that route right now due to budget constraints...

Thanks for the help!

Ceylonc:

You will have to have the Redding Competition Seater die floating sleeve reamed with the chamber reamer before it will work with fireformed brass. A quick job if you have the reamer.

I use the Lee collet die for neck sizing my 260AI brass. The best neck die I have used for this caliber, and a great value.

The only other investment that you might make would be a Redding body die in 260AI. They do make them, and I got mine from Russ Haydon. He had one on the shelf. It makes the process of bumping the shoulder back every four or five neck sizings an easy proposition.

Cheers,
 
Chris,
Wouldn't you have to run a 260AI reamer into the Lee Collet Die too? Or will a 260 work?

Which benchrest seating die is easier to alter, Forester or Redding? What, exactly, do you have to do?

Any drawbacks to using the 7-08AI sizing die to bump the shoulder back on a 260AI?

Bill:

The Lee collet die in straight 260 has plenty of clearance for the AI shoulders. No modifications necessary.

I have modified a number of Redding Comp. Seater dies, and know for a fact that the sleeves are not hardened, and ream very easily with a chamber reamer. I have no personal experience with the Forster variant, but have seen them described as also having easily reamed sleeves. In fact, I believe that Forster,and possibly Redding) will sell blank sleeves in your caliber of choice, making a complete custom die a possibility.

I can see no drawbacks to using the 7-08AI body die to bump 260AI brass, as long as the reamer/case specs for both are essentially identical in the body and shoulder area.

Hope that this helps!

Cheers,
