Re: Case Runout
I've got my RO problems handled thus far, took some work but now I'm down to .000" - .002" at most on the Ultra. The nice chamber in the new 30-338 LI is staying under .001" no problem, but those are neck turned and reamed with the K&M and the inside cutter mandrel so I'd expect better numers anyway.
The Ultra's were neck turned on the Forrester and it just doesn't do as good of job as far as consistancy in thickness goes. I had to loosen the collet and let it float a bit to keep from torquing the neck on the mandrel to one side so I didn't end up with one side cut thinner than the rest. Seemed to work much better but I wanted to keep the variation less than .0005-.001" so I got the K&M. Now we're really talking consistancy... under .0002" no matter where you check it. It also cuts a LOT nicer too. Doughnut removed and neck turned all in one operation as well.
I'll have to try indexing RO at a few places and see if it steers the groups around.
I'll be testing a product in a few days for measuring seating force in PSI, it will be released not too long afterward, soon as they know it's working as expected. It has a digital readout and uses a sensor under the shellholder, can't say muck more than that yet, not sure they want the specifics out on it quite yet. Should be a great tool, I know I could use it about now! I will say that it won't wear out, reads more accurately and has higher resolution than the competetors does, but will cost a bit more... I think. I talked with Ken at K&M about an electronic pressure sensor type measurment system a couple months ago and he said the cost of making them would be steeper so he didn't want to go that route when he did his. Ken knows his electronics too.
The guys developing this and some other very awesome things are intent on leading the precision shooting and reloading crew to new levels, all at a price the average shooter can also afford, which is the criteria. Stay tuned...
A new style chronograph is in development as well, not relying on "light". Consistancy and accuracy with this design, as well as the price tag will get everyones attention. It might be a little while if it all works out as expected, but I think it's coming too. [img]images/icons/smile.gif[/img]
