Lube inside case neck?

[pepperbelly]

I read, with great interest, the thread about waxing the inside of the case neck thread. I noticed several people saying it was nothing new and helps equalize neck tension.
I have a question about doing this when I load for a semi-auto. Should I?
I use Imperial wax and use a Q-Tip to be lube inside the case neck but have always removed the wax as much as possible. That was for a bolt rifle.
If I leave lube inside the case neck would I run a risk when loaded into a semi-auto of seating the bullet deeper on the feed ramp?
If so I won't try it. If not it might be worth it to see what leaving a little wax inside the neck.

Oh yeah, for the grammar nazis here ellipsis uses a space between the "dots", . . .

Why wax the inside of the neck when you can just rub a little imperial on the bullet before shoving it in?

Handloading rookie here... I've never done it, but the above seems like a good idea in comparison to lubing the inside of the neck.

Re: Lube inside case neck?

i like to polish the inside of the necks to make equal the let off.....the sex wax is so you don't jam the brass thingies in the die.....


steel wool fed to a nylon brush on a floor style drill press makes for clever polish jobs.....

chrono says single digit SD's

Re: Lube inside case neck?

What I am concerned about is the bullet seating deeper when it hits the feed ramp.

Crimp is your friend. It will over ride sex wax. Press a loaded bullet point first into your bench. If the bullet moves add more crimp. If it doesn't load away and feed the mag.

Cheers,

Re: Lube inside case neck?

Imperial Wax if applied to the inside neck area can attract and contaminate your powder. Yes, it is only slight, but still. If applied to the bullet, it would not be my first choice, but I am sure it works ok.

I use Lee white paste. It dries,*DRIES*, quickly and absolutely will not contaminate your powder or mess anything up. You can use an appropriately sized brush to quickly and easily apply it to the insides of your case necks. Less to go wrong.

Good shooting,
Gary

Re: Lube inside case neck?

Since switching to SS media I have been thinking about using a dry neck lube of some sort, NECOs and Redding both have kits, Former Naval Person suggested using HbN suspended in denatured alcohol, I think because my brass is so clean it would help, I do know for a fact that my seating force is greater with once fired cleaned in SS media than it is with fired brass with the neck brushed clean, the leftover residue acts as a lube, car wax or Imperial are a poor choice IMHO for inside neck lube

Re: Lube inside case neck?

If you are using enough imperial that a granule of powder will stick to it, you are applying way too much, and in the wrong spot.

In the case of boat tail bullets, do not apply any to the bottom or the angled tail. Just the sides where it contacts the neck.

Re: Lube inside case neck?

How could I apply graphite inside the case neck, and could I just leave it?
If this starts to get too complicated I will just clean the neck as usual.

Re: Lube inside case neck?

I use the Imperial dry lube, it is just graphite, and could probably be found cheaper as such at a hardware store, but I do recommend the ceramic aplication media which comes precharged with the imperial dry lube.

http://www.sinclairintl.com/.aspx/pid=33148/Product/Imperial_Application_Media

I just dip the case neck in prior to neck sizing and since it is graphite, no problems with powder contamination. No need to clean it off.

The ceramic beads do a good job of getting just a little graphite in the neck and don't clump up.

Re: Lube inside case neck?

I use the Redding/Imperial dry slick beads. I dip my brass in it when I'm using the expander mandrel. Much cleaner than wax and there is nothing to wipe off or contaminate the inside of the cases.

Re: Lube inside case neck?

I'm just going to barge in here and ask a dopey question - if you take it as "mean-spirited," be advised it is not.

Why would you guys care about such an obscure and relatively unimpactful aspect of reloading? What additional accuracy do you think you could provide yourselves? An additional 0.05 MOA? You're not benchrest shooters; are you simply trying to bag the tightest groups for bragging rights?

Sometimes I read this forum and think, "Now there's some folks not seein' the forest fer the trees."

If it's simply to see how much more accuracy you can dial into the solution, just an academic exercise... I have to ask, "Do you have everything else wired down - tactics, wind calls, reading mirage, shooting positions, target ID, ranging, etc.? You guys are down to this?"

Re: Lube inside case neck?

Its just another piece of the puzzle boltstop. Some people like the 50 piece puzzles. Some like the 5,000 piece puzzles.

There are many reasons people lube necks. It's not like you lube your necks and magically you shrink groups. It solves a problem is all, and those that think its magic didn't know what problem they had to solve in the first place.

I've seen neck lube reduce runout, increasing accuracy.

I've seen it remove OAL variations by reducing seating force.

I've seen it reduce extreme spread.

Granted, if you are not having a problem with any of these things then it likely won't help. I just started doing it on 338LM with 300gr scenars. There is a LOT of that bullet going inside the case, and it seems to reduce the force required to seat the bullet about 3x.

Lots of different reasons for doing it, none of them bad. I too read this forum and wonder sometimes. Except I wonder why some people think its glorious to NOT squeeze as much accuracy out of the gun as possible.

Re: Lube inside case neck?

I use Hornady spray lube, and if I don't spray at a 45 degree angle- necks up- to get some of the lube into the necks the .223's will get stuck in the FL sizing die...

this is but a small effort in a process, a process to eliminate variables that lead to consistancy and predictability.....which leads to confidence......some matches are won by that one well placed round........

Re: Lube inside case neck?

We're all looking for more accuracy in one way or another. Otherwise, we'd just go out and buy the cheapest guns and ammo and go play Rambo somewhere. We damn sure wouldn't be spending any time on a site like this where people can actually learn how to make that bullet go where they want.

I also use Hornandy's One Shot in my process and intentionally get a little in the neck. After resizing and cleaning the neck ID out with a few swipes from a bore brush there is very little lube left in the neck. I dont crimp and run about .002 tension. I have reloaded for an AR10T for years and have never caught it in bullet set back and I tried hard to for a while at first now I pay little attention. Do the same for my LTR. SD's running around 10 and consistant.

Re: Lube inside case neck?

boltstop, I think most of us here suffer from a certain amount of OCDisms. lol

Unless something is out of whack it's never 1 thing that makes a big difference but alot of little things can and do add up to 1 big thing.

I'm not a high volume rec. shooter so I'm ok with spending any and all of the extra time it takes to make things as perfect as I can. If I were a high volume shooter I'm sure I wouldn't spend the extra time like I do now and my single stage press would sit idle collecting dust instead of my Dillion.

Re: Lube inside case neck?

I tend to think the same way as boltstop, but if you like it, do it. I find reloading to be more than just making accurate ammo. It's good therapy too...

 

[madd0c]

Re: Lube inside case neck?

Heck, I use graphite in the case necks because I don;t like the noise the expander ball makes when I don't use it

And it really isn't much of an extra step to dip the neck in a jar on the way to the press.

Re: Lube inside case neck?

I use the neco moly. It definitely reduces seating pressure AND I started seeing much more consistency in my seating OAL using my redding comp die. At first I just thought it was OGIVE variations but after using the neco moly powder, my OAL when seating are all usually within .001" using Amax bullets. Out of 20 bullets I might get one that's off by .002" or so when seating.

It seemed to help with reducing some runout and putting a ring on the bullets. I attribute this to less seating force.

With the ultrasonic or SS method of cleaning, I think some lube is helpful as there is no carbon left on the necks at all to provide some barrier between the bullet and the bare case neck...just my .02

Re: Lube inside case neck?

Being the professional mechanic that I am, and a cheap fuck too I went to Ace Harware today and bought some extra fine graphite powder for $1.79, and then I went neck door to Krogers and bought a baby food jar of peas for $.44, I already have BB's, so for the total investment of less than 3 bucks I have a inside the neck lube tool, I cleaned my 260 FL die expander with denatured alcohol, resized 5 cases and the exit out was pretty smoothe, concentricity was less than .002 on all 5 cases, still too early to tell if this will be included into my routine, how this step effects seating force is yet to be determined, and finally how the graphite effect the groups and ES\SD
