Jackie,
You mentioned in an earlier post that you use Redding sizing dies, are they full length or neck only? Standard or bushing dies? or are they a special/hybrid. Just curious, I would like to improve the runout on my reloads. I enjoy your imformative posts. By the way, nice shooting last weekend.

Dies

The die I use to full length size, decap the primer, push back the shoulder, and size the body started out as a regular Redding PPC full length die, which will have a neck that is about .263. (remember, this die uses a button to bring a stock PPC case back to size. I grind this down so it does not interfeer with the neck). Using a carbide cutter, I bored the neck portion out to .265 to be used in conjunction with my .269 neck. I then machined the OD of the bottom 5/16 in length to about 1/16 thick. I then pressed a ring over this about .003 tight, closing up the bottom where the web of the case enters the die. I then, using emery paper, polished that bottom portion out to where it sizes my cases, at the web, down a couple of tenths. This die produces cases that are dead straight, and all potions are still hardenned..
This die, of course, uses no bushing, which means I never change neck tension, I do the majority of my tuning with my tuner, and a few tenths one way or the other with the charge, depending on the humidity.
The seater is just a stock Redding seater. It happens to fit my sized cases pretty well.
Last week end, for a reason unknown, I was getting about .002 runnout in my loaded rounds. My dies usually produce about .001. I did do something that I normally do not do, that is, I straightened each round to within .001. It only took a minimum effort, so I didn't mind doing it. If loaded rounds runnout much more than .002, I think straightening might do more harm than good by compromising the neck tension, or even bending the bullet.
Incidentally, I took a little heat from Gene Bukys, because he has heard me rail against straightenning rounds.. I prefer my Crow with salt, pepper, and ketchup.........jackie
 
Dick,
Hornady makes a really straight one piece 6PPC die. The neck is about the right diameter for a .262 chamber, and the base will size the bottom of my Boyer #3 design reamer. The only hitch is that the shoulder is sized a little over .002 in diameter. Since a friend was having a rifle built, we ordered a reamer to match the die, easier and cheaper than the other way around. This die produces brass that runs out a couple of tenths at the most. The other part of the deal is that I have found that the higher the neck tension the more critical seater fit is, particularly with flat base bullets. I found some improvement with a Nielson seater that is barely big enough in the neck to allow seating a bullet, and which is a closer fit in the body. Another good way to go is to have a seater made using the chamber reamer. As far as straightening goes, if you are going to, I believe that the H&H is the easiest to use and most versitile, covering a large range of case sizes. I have tried several others and asked about the ones that I have not had in hand. Another way to get a little more straightness is to use a more gradual chamfer angle.
 
Identifing Reamers

This may belong on another thread, but!!!
I acquired a set of 22RF Freeland Match Reamers. How do you identify the manufacturer of said reamers?

Thanks for sharing what some might consider proprietary information. It has given me a couple ideas. I appreciate it.
