Thread: Bad Reloading Press ??

What do you call heaps of runout?
And how much slop is there in your press?

My 1975 vintage RCBS has about 3 thou slop at the top of the ram when fully raised, measured with a DTI. I have to push hard on it to show that slop. I can still produce ammo with only 0-1 thou runout using that press.

I've no doubt a really sloppy press won't help matters.

Have you measured your necks runout b4 seating a projectile?

My worst runout was produced, over several calibres, whenever I used Redding Body Dies. Absolutely no real support for the neck.

For neck sizing only I had ended up using the Lee Collet dies. Ended up with about 4 different calibres in them. Runout using them is minimal.

Otherwise, in the last year I have changed my whole process. Whereas I used to use bushing dies for neck sizing (pre collet die) and full length sizing I have parked them up. I actually purchased Whidden's super expensive bushing FLSing die for my 308 that I use for FTR. Runout with the Whidden was terrible.

I bought Forster full length sizing dies for some of my serious target shooting stuff (6mmBR, 6.5x47L, 308). After having several other brands I feel the Forster are top notch.
I now anneal after every firing, FLS with the Forster with expander button removed, and then expand the neck to my desired neck tension using a expander die.

Otherwise for other catridges use a combination of standard die sets and Lee Collet.
