Your concensus aside, the question is, "How well does the tool work?"
I am in the middle of a test to prove whether or not this or any other tool that actually
straitens out run-out is worthwhile.
I purchased the Hornady to see if it could save poorly loaded ammo (Like the factory stuff)
and some that did not come out very good for one reason or the other.
There is no doubt that concentric ammo will improve accuracy. How much is part of the test.
I loaded some ammo and sorted by amount of concentricity(Run-out) and took some of the
loads that were over .001, .002, and .003 and straitened them in groups of 3 from .001 to
.000 (If I could get them that close) and from .002 to .001, and .003 to .002 to see the
effects of truing them on SDs and groups.
I found some factory loads that were .006 to .008 out and found that is you try to true them
to much they will loosen the bullet grip of the case(Not Good).
Loading good ammo is the best cure for this problem but even with the best technique
sometimes they will have run-out, so the question is can you fix it ?
So my plan was/is to first sort to find the least run-out and use them for the long shots. Then
use the ones that are only .001 or .002 out for second or backup shots.
Then see if buy truing the stuff that is more than .002 out of true if it is usable.
I will tell you this the tool "WILL" true the ammo up close to .000 some times but not all ways
so I settled for anything under .001.
Whether the trued ammo will improve or match the performance of the loaded ammo that is
true after loading, remains to be seen.
I will post an unbiased report as soon as it is finished. and it does show if your loading
tekneek is poor like a lot of other tools will. but if will improve the ammo I want to know.
