Brushing lube into rifle necks

[Nature Boy]

It did fell like it required less force to seat. I should have thought to measure BTO of the two groups to see if there was a difference.

You dipped the case only or the case and the bullet... might not even mater just verifying what you did.

Interesting! Well, nobody says this has to end the experiment, right?

BTW: NICE! Rifle.

Both. Case neck 3 times and bullet base 3 times.

Those unfamiliar with this stuff, it’s a graphite powder that you mix into these little plastic beads. You dip the case neck into the beads and it transfers the graphite

Two things be careful that you don’t touch the neck if you have any sizing lube on your fingers the little balls will stick.Occasionally you have to shake or agitate the powder and balls.Put the lid on don’t try to just swirl them they will fly everywhere.I’ve used brushes and a-tips but I like the graphite balls but it’s easy to make a mess.

Excellent, thanks for the clarity.

Here you go.

Bottom Line: it seems to make a difference

Sporterized 03A3, 30-06, 169 SMKs, 57gn IMR4350, RP brass, Federal 210 primers

10 rounds each, trickled to the kernal (+/- 0.03gn). I used Imperial dry lube on the necks with.

Ok, but now you have to do it with brushed but carbon fouled necks vs squeaky clean necks

That's a test I haven't seen yet and was interested in... how many firings to good carbon seasoning?

 

[Hole maker]

Don't you need some lube inside the neck in order to get the expander ball back out of a sized case? I've used tooo little lube and run into problems with the neck being pulled out enough that it makes chambering a round problematic. I just use a little RCBS case lube on a Q-tip for most rifle cases. The Hornady spray works good enough for the slight taper of .300 BLK cases.

reddog I use Hornady One Shot for my cases and also use a Q-tip inside the rifle case necks but I ether tumble or use Denatured alcohol and soak them and wipe with cloth inside and out, lubing case necks prior to sizing helps stop neck stretching, don,t you check case length before loading?

LOL!!! No good deed goes unpunished @Nature Boy

I’m not surprised about the easier seating or the lower SD/ES numbers... but the increase in avg velocity surprises me a little. I was thinking maybe a few FPS - insignificant numbers - at best.

I’m also curious if the “raw” wet tumbled “too clean” case necks are harder to start a bullet seating. .30-06 has a strong neck and shoulder but think about something with a shallow angle and thin case... having to “get on” the seating stem to start a bullet could change the shoulder angle. (???). Interesting topic.

1. wet tumbled no carbon in neck
2. carbon fouled neck
3. carbon fouled neck and brushed

A strong maybe. I’ll think about it.

What I’m curious about is how introducing lubed necks would effect an established load tuned without lubed necks.

Honestly, my target rifles and their tuned loads produce SDs in the singe digits without lubing necks. The difference may not be discernible.

This level of testing might be more your interest level... it's the video that keyed up my intrest....

I’m assuming this is Muzzle Velocity, and can only image what that might look like on a 1000 yard target.

Yes, MV

Need one of these.

I suppose what I’d want to know now is how neck treatment affects some of my target loads.

Based on feedback in this thread, the worst thing I could do is nothing. Unfortunately, that’s exactly what I’ve done to the following:

.308



.223



6BRA

Can't say I'd be messing with loads like that either....

 

[JFrank]

I would attribute this to the one and only Nature Boy’ the rest of us need a little help..

Nicely done NB..

 

[Nature Boy]

I’m not trying to say there isn’t room to improve. I’m curious to see what would happen

Agree....Most interesting! Wish I were younger! I left a couple of days and look where it went..... I remember when I first got my Thumblers and pins, and the first batch out was LC 7.62......had a hell of a time getting it lubed enough to even size it. That's when I learned that brass really is porous enough that a wet tumble can and does relieves it from all traces of lube and makes it nearly unworkable.

I can imagine seating would be easier applying on both bullet and neck! I just worried that would be too much and would cause slippage in the neck. Powdered mica worked on even my brass from hell, but graphite is the better lube no doubt.

Graphite is excellent stuff, and best of all it sticks. I first used it on Pinewood Derby cars my boys and I built. No graphite no win races. My powdered graphite came from NAPA auto parts, super fine in a large bottle.....the balls would make it much easier to use on brass....I just used a cheap pipe cleaner, to burnish it on, and a rag on the outside. A royal pia. Have to try this.

Wonder if anyone has ever tried just graphite burnished into the whole case and skip other lube all together. Wishful thinking maybe, but if it worked it would mean clean and dry brass going down the case feeder downtube. I think that would make me go to the trouble....probably a pipe dream.

I'm old school I guess, been using one of these for as long as I can remember

Hey, I have one of those Bonanza Case Neck gadgets too. Also have a half can of motor mica that I'm still working on from mid '70s. Like Imperial Sizing Wax, this stuff last forever as you only need a little dab to do ya.
