ballistol for sizing lube

[NHgunNut]

I love the lee collet dies. For 60 bucks lee will custom make you a set of dies to fit your gun!(you send them a few empty shells and 1 loaded one) I have virtually no runout with the lee collets, and to get rid of the pesky marks they leave on the case necks i simply turn the shel 1/8 turn and collet size again. if you want more neck tension put the collet mandrell in a drill and run some super fine sand paper over the shaft to make it .0001 smaller.

I use a Lee Collet die for all my neck sizing. Clean cases stay clean, no lube anywhere after sizing. Also less work hardening. No more undersizing of the neck first then running an expander through it to bring it back to the correct size.

amlevin, Every time you use a Lee Collet Die, or a die that only neck sizes, you're producing a cartridge/case that never returns to its original designed dimensions until full length sized. The more often you fire it, without full length sizing, the more often you're producing a case that continually differs from it predecessor, until such time that it can no longer be chambered.

Full length sizing, each and every time you re-size, preserves the original dimension without overworking the brass. It's the lack of frequency that leads to overworking and case hardening. The more often you return to the original dimensions, done in minute or very small proportions, .0005" to .001" or to minimum SAAMI specs [Redding dies come to mind], the less work or force is needed.

What you say may well be the case and make good 'fodder' for a term paper in a metallurgy class but I find that the Lee Collet die serves me well. I use it until the case is hard to chamber or sticks out of my case gauge too far, then body size it with a Redding die and then anneal. So far I'm up to well over 30 loadings on some commercial Winchester brass and no failures. Almost as many on my Lapua cases.

Bottom line is I don't have any "lube in the neck" issues or for that matter, premature case failures. Last night I checked run out on a batch of loads and it was .0005 or less on 50 cases neck sized with the Lee Collet.

amlevin-

what type of shooting are you doing?

I tried neck sizing for a long time, primarily because it was so convenient to size with wilson neck dies. Keeping track of 50 pieces of brass, after three or four firings, all the brass was different sizes and groups werent as consistent. Switched over to FLS with a harrells die and now all the brass is always the same size, its being sized just marginally, and its definitely made a difference in the consistency of my groups.

I wish I could make neck sizing only work...

amlevin-

what type of shooting are you doing?

I shoot a Remington 700 5R Milspec in .308. While the groups from this rifle have always been "good" I now have sub 1/4 MOA results from my neck sized cases on a regular basis.

I have several hundred Winchester cases and cycle through them before sizing and trimming. I don't pay as much attention to the case dimensions as I do to weight. I sort by weight after cleaning in Stainless Steel pin media, neck sizing, and trimming. With the large amount of cases to sort, I have boxes of 50 that weigh within .2 grains of each other. Random tests show their water capacity to be almost exactly the same. Who knows how they'd perform in a custom rifle but this "factory stock" rifle sure performs well.

If you have a lot of residue, you're probably using too much.

It appears you are correct mr. boss man.... I was using WAY too much.
