Lubing inside neck of rifle brass for resizing

    OK, been handloading for at least a couple of years. I started with pistol and now reload 223 for my rifles. I know that lube is not required for pistol reloading and I have tried a few different case lubes for rifle brass - Hornady One Shot, Dillon, and Imperial wax.

    After getting a case stuck with Hornady (after thousands of successful rounds), and not caring for the Dillon lube (seemed messy), I settled on Imperial. I just swipe my finger across the wax and apply it to the case. It works wonderfully for me.

    Using this method I was not getting any lube into the case neck, so now I deliberately drag my fingertip across the case mouth to get a bit of lube on the inside rim of the case.

    Once sized, I wipe the cases clean using a rag with some alcohol.

    The problem is that when I drop powder into the cases, it sticks to the wax on the inside of the case necks, so I have started cleaning the necks with a Q-tip, but this is time consuming.

    With the spray lubes (Dillon and Hornady) I never had a problem with powder sticking even though I am sure some of the spray was entering the case necks due to the angle of the spray.

    So....my questions for you all are:

    - Do I need to lube inside the case necks?

    - Is there a better way?

    I suppose I could continue using my current method then tumble that cases a second time to remove the lube, but really wanted to know if it was critical to lube inside the case necks.

    Yes, it is a good idea to lube the necks.

    The best way to do it I have found is with a nylon bore or bottle brush.

    Roll the brush on a lube pad.

    Then run it in & out of the case neck.

    It will leave just enough lube to ease pulling the expander back out of the case.

    But not enough to need cleaning afterward.

    I think you might need to clean the expander in your die.

    It should be scraping all the lube out when expanding, leaving none in the case for powder to stick too.

    You may have a big glob of lube buildup on the expander button so it is leaving a mess behind.

    Dry mica. Never have to do anything if terms of recleaning the neck that way.

    Do you need to lube inside the necks?
    A - With a pull-thru expander, the answer is sometimes. It depends on how much the die undersizes the neck before pulling the expander ball thru. And how thick your brass is. With my Lee rifle dies, I have not needed any inside neck lube. With my Hornady, yes. The 2 Lee dies I have size the neck just enough to work with most brass, but a few pieces have had to be culled here and there. My Hornady die sizes the neck far enough to work with any brass... but undersizes the neck so much that pulling the expander ball thru is very hard, even with lube.

    So try it with no lube and see. If there's no undue resistance during expanding, then you don't need to lube. So long as you aren't wet tumbling, the carbon left in the neck will be enough to prevent any cumulative galling.

    Is there a better way?
    A - Yes. Expand with a Lyman M die. When you push the expander in from the top, there is no problem; even with no lube, expanding is effortless. The issue arises with pull-thru expanders. Just like a Chinese finger trap, they can get into a positive feedback loop where the harder you pull, the tighter the fit, which makes you pull harder, which makes the fit tighter.... = stretched and overworked brass and a tired arm.

    I use imperial on the case, and dip the mouth into white dry mica, then run a brush gently onto the case mouth before resizing. Next, I clean the primer pocket and then tumble for a white to remove he lube.

    I use the Dillon spray on and have never had a problem. But as for your specific question, yes it is a good idea to lube the inside of the neck. If you have any one shot or Dillon left, just put a dab on a Q tip and give the inside necks a quick lube.

    And to clean the brass up after resizing, I just fill up a cup with alcohol and give them a quick bath. With Dillon it works great, don't know how Imperial cleans up with alcohol though?

    I use one shot. I put the cases nose down in the rcbs tray and hit the cases with the one shot. The lube runs down the case to the neck without entering inside. Works the best for me.

    If you're going to use Imperial,why dont you go ahead and spray One Shot on the case mouths like you used to and just use the Imperial on the rest of the case. Personally I use One Shot rifle cases, so far so good.

    I use one Shot Myself.... i like the Wax but it takes longer so just toss about 40 brass in cardboard Box.. blast it a few times with one Shot as im bouncing box around....

    Then 1st Case I rub Synthetic Motor Oil over neck.. and some inside...

    Then i go to Town...

    Once I get about 200-300 done I toss em in my Tumbler for about an hour... makes the cases nice and shiny again and removes any residue from the lube

    I found that prepping all my cases.. de-prime and size... at once then doing all my loading at a sperate time speeds up the entire process alot for me....

    i have a lee pro 1000 but only load 1 case at a Time when loading. But when i am de-priming and sizing I load the Case feeder and just BLAST away... can do about 40 in less than 5 minutes..... and can pop out about 300 ion less than an hour...

    Anyways hope this helps some

    I, like you, wipe a finger across the opening of the neck to put a minute amount of lube inside the neck. I don't do it on every casing. I have not had problems with excess residue.

    I use the dry-mica on about every 5th case , seems to keep things smooth

    I use Imperial Case wax on a RCBS neck brush... run it in and out once ....

    I smear my fingers in the wax and rub them on the brush ... reapply about every fifty cases or so.... I use carbide expander balls in most of my dies also.... slick as snot....

    Another dry mica fan here. I've tried the neck brush after rolling on the pad with RCBS lube and that works great also. With the mica, I simply insert the neck of the case in the mica and tap if it looks solid in the neck. This will drop out the glob and leave enough to drag over the expander on the way out. No complaints after many many years of this method.

    I use a Q-tip to do the inside of the neck, (imperial) do about 100 and then I stick everything in a jar of acetone for a hour and roll it around and shake it up (after being deprimed) Then pour it off into another jare using a strainer to catch the brass and it dries real quick, cleans everything up real nice

    I use an RCBS case neck brush handle, but instead of the case neck brush I use a slotted cleaning jag and a cloth patch. I get the patch saturated with lube and pop it inside the case mouth before sizing. I bought the little Lyman mica and brush gizmo but I can't tell any difference between using mica and running them dry.

    Since you are using Imperial Sizing Wax, also use their Dry Neck Lube (or other mica). Dip the case mouth in the Neck Lube, then lube the rest of the case with Imperial.

    After sizing, it is probably a good idea to remove the Imperial, but the Neck Lube can be left inside the case mouth. It will not contaminate powder or the primer.

    The only rifle round I load is 30-30 and have only loaded about 350 rounds but, I didn't lube the inside of the case neck for any of them. I use Mink Oil on the outside of the case and they resized easier than the dry 9mm brass I also reload. I see no need for lubing the inside of the case mouth.

    Famous last words perhaps but, so far so good.

    Thanks guys.

    I use both Hornady and Lee rifle dies and I'm not having any problems getting the expander out of the case without the lube, just wanted to know if I was causing undue wear on the ball. I suppose I'll just keep doing what I have been, and swab out the necks with a Q-tip (or re-tumble) before dropping powder into the cases. I'm not a high-volume handloader - rarely more than 100 rounds per sitting on a single stage press - so it's not a big deal.

    I may also pick up some mica and give it a try.

    Measure the run-out on a few fired cases, then resize and measure again. That will tell you if you are distorting the cases. Bushing sizing dies are the way to go.
