I'll see what I can find out.

I have some data from the factory. Once you can access the pm features send me your eMail address and I'll forward it.

Brilliant!

What is the PM feature?
Thanks again
Harry

Also out of interest what press do you use? I am hearing great things about the forester Co Ax press.

PM = private messenger, when you have 15 meaningful posts admin will give you full access to all the forums features, including sales, the library and PMs

The CoAx has a very good reputation, especially for achieving low runout (probably the best runout from a single-stage press, without going to an arbor press and hand dies). It is also expensive and uses an unconventional system for mounting dies.

My view, and you can be sure there are others who disagree with this, is that the fractional improvement in the SD of runout you may get by using a CoAx is pointless. Once runout is less than 0.002" or 0.003" I don't believe you'll see further benefit on target - the barrel, rifling and physics of gyroscopic stability will do their job. Reducing runout from 0.002" to 0.0015" is a pointless exercise. Now, if your runout is worse than 0.003" then it warrants improvement, but that is more a factor of process, brass and chamber than choice of press.

A good shooter and reloader will get great results whether he uses a CoAx, a Rock Chucker, a Lee Classic Cast or pretty much any press. The process, the components, and the dies are way more important, IMHO.

I am unconventional in this respect (perhaps in many respects).
I use a 'vintage' RCBS JR press, plus a couple of Dillon Super 1050s.

Thanks for the reply. I am getting a lot of run out at the moment however I think I have just found the cause. I have been using the K & M expander mandrel as I took the one out of my redding expander die and I noticed it’s giving me horrible run out.
I have just ordered the Sinclair expander die so hopefully this should sort the issue.

Chasing runout can be something of a leap into the wormhole. I remember thinking that a concentricity gauge was essential, and ordering a 21 Century gauge. That was about the time runout ceased to be a problem for me, and the gauge is rarely used now. What gauge are you using? I have the feeling from trying a few that they some are more sensitive than others (depending on how the round/case is supported etc), so it isn't always meaningful to compare absolute runout measurements between different gauges.

Thanks,
I have the Sinclair gauge.
Like you said, chasing run out can be like going down the ‘rabbit hole’ however I seem to be getting problems with my expander mandrel. Maybe changing this will help.
What calibers do you shoot mainly?

Pretty much just .308, as it's dictated by most of my competition rules.

Where about do you shoot?
