Thread: Neck tension

Obviously consistency is key here but what have you found gives best accuracy?
Some swear by a heavy crimp others by as little as possible.

getting rid of the epander expander ball was the best thing i did
go busing dies

Any of the following:

Good brass
Neck turning
Annealing
Neck sizing only
Crimping

Yea yea yea but how much tension do you like and how do you measure it?
If measuring inside neck dia then brass thickness,brand, anealing could all give different tensions for the same measurement.

And here I was thinking this was going to be a massage thread.

haha, was waiting for someone to bring up the measurement issue(s)

as far as reloading is concerned, i'm of the "if you can't measure it, dont fuck with it" variety

Bushing dies

Measure loaded dummy round neck diameter
Use correct bushing .002 smaller

Job done

If you use a bushing die but the neck has a dent will it pop it out or not?

tryed less or more?

Also 2 thou on say a 17 cal would be a lot compared to say 2 thou on a 50 Cal yes?

Abe, the problem with that is that the OD of a loaded round may or may not have any relation to the chamber.

Shoulder bump, you're looking at a fire formed case, and sizing relative to that... With a fixed diameter projectile, but variable neck thickness and variable chamber dimensions it all gets a bit random. If you are using a high-end barrel, and can specify how tight you want the neck in terms of the reamer, then turning the necks, and using a known size bushing makes sense.

Also, .002 bushing on very thin brass won't give you the same tension as on thick necks. So to get consistent tension, you pretty much have to turn the necks, which can cause a whole other set of problems with an average "loose" neck chamber...

I think the answer to your question vc is no...
