Neck tension vs accuracy
« on: May 14, 2017, 06:26:05 PM »
Is there a significant amount of difference between .001 and .002 neck tension and related accuracy?

For my .308 I've got a Lee collet die and it came​ with a .001 neck tension rod. I was given a .002 neck tension rod for my birthday.

Standard is .003. For a hunting rifle, neck tension is the least of your worries.

Hmm interesting. I'm going to run a few batches of varget with br2 primers with the 165gr gamekings.

In your opinion where would you rank the critical areas for accuracy when reloading?

My last loading would have 2touch then one about an inch in a random direction. Would neck tension help this or would seating depth be a better area to adjust?

what I've found out about neck tension is you want it the same.

The only time that i had the issue of two touching then one flyer about an inch away, was when the load was pretty hot and it was a stock fluted #3 barrel.  It would get hot and that third shot would always wonder.  I would shoot 2, then wait 5 min and shoot the 3rd and it would be right there.  Another thing you could do is shoot over a chrono and make sure that your fps has a good average.  Are you separating your brass for how many times they have been fired?

If one was to fire let's say four three shot groups letting the barrel cool in between groups and you have two touching and one out.

It's a free float issue or a bedding issue. If it consistently produces the same 2 in and 1 out groups.

Like biggerhammer said, for general purpose hunting it's not important.  But if you want single digit ES it's pretty critical.   I've played with different amounts of neck tension for long range precision.  I've settled on 0.002 and achieve it by neck sizing using a carbide turning mandrel in a Sinclair bushing.  If your looking for consistent results and low ES you must have even and consistent neck tension.

Hmm it's about 2-3 minutes between shots in a heavy barreled savage 10t in .308. in an accustock. I didn't think barrel heat would be that big a factor

Name that case! :tup:

I don't really worry that much about neck tension. If it holds a bullet reasonably well I'm ready to roll!

That's not an STW case because there's no belt so I'm going to guess something necked down off of a RUM case with the shoulder blown out and pushed forward.

It's my 6.5 Badger. A necked down, blown out .338 Ultra Magnum case with a 40 degree shoulder.

From left to right.

Left .458-.375 Ultra Magnum 500gr Hornady (I've taken one bull Elk with it). Second from the left is Yorke's creation .375 BME, a blown out 40 degree .375 Ultra Magnum with a 350gr Sierra Match King. Third from the left is the 6.5 Badger with a 160gr Matrix VLD. Far right a standard .338 Ultra Magnum case.
