Hello!
I'm reloading 6.5 x 55 with Wilson neck dies and Wilson bullet seater.For your experience why the cases, even if I'm resizing them with Redding Body dies, don't fit into bullet seater completely (about 0,010" less)? No problem with neck dies. Where is the mistake?
Thank you

I would like to know where the .010 comes from....is the result of taking specific measurements with a calibrated instrument?

A dial caliper usually is good enopugh to get this data.....measure the bullets and the neck ID...

what do you get?

Wilson dies are known to be minimum size in the body. I have several sets of Wilson dies in which the case hangs up in both the neck sizer and the seater. The worst is a 7MM Rem Mag. It is due to the Ruger chamber being so large.

Vapodog, I try to explain but is not easy, I'm from Italy, sorry. I tried to insert a new case without a bullet into the seater, it's ok, fit perfectly. When I take a case fired one time don't fit completely. I resize with Body dies but when I insert the case into the seater the bottom of the case goes out slightly the recess part. Result: it's the bottom of the case that touch the base, not the seater and I haven't consistency among the rounds!
I hope to explain me!
Thanks

Only two things that I can think of which prevents a case from entering a sizing die fully after it's been fired . Number one is the neck is to long on the brass, if it's been fired in a particular weapon and this is not the case and the body is " fat " near the base of the cartridge . This usually means that the weapons chamber is Large or damaged .

New brass fits fine right ?. Once fired your not able to size the brass properly to the die your using correct !. Suspect chamber would be my guess . ...

Genoa, cases don't have to fit all the way into the seating die.

If the seating stem will adjust down far enough to seat the bullets, I would back the seating die out enough to make sure that it does not contact the case.

The sizing die sets the case dimensions and neck tension. Unless you're trying to crimp the bullet just use the seating die to get the bullet in the correct position to seat it.

Fjold is correct. You don`t want/need contact between the case and seating die if possible.

The contact will increase the chance of seating depth variations with any seating die as it may not contact each case evenly or even at the same point. Back the seater out until no contact is present and adjust the stem to seat your bullet. I think you`ll find it works great this way.

Unless the case is pushed flush with the bottom of the die or a spacer is used that is used to stop the die the seating depth will never be consistent. You could use a precision flat ground washer to space the die upward slightly. the other solution would be to machine a recess (counterbore) in the base that is used with the Wilson die.
The top of the Wilson die stops the seater punch so the seating depth consistency is dependent on the bottom of the die stopping at the same point.

there is a good article in this months handloader magazine on loading for the 6.5x55
there seems to some issues with brass sizing that they mention in this article

Maybe you need to get a Wilson full length resizer.I will bet you have no problems using your seater die if you FL size with a Wilson FL die.

You could contact Wilson and ask them what they would recommend –
