- Here is the question: 300 blk brass- all brass has been resized and case guaged-
I am going to reload using a Forester bench rest die- do the cases have to be re lubed
before I seat the bullet- as most if not all the lube is off after I resized them-
Lube to seat the bullet? No. I’ve never even heard of doing this.

You only lube the case when resizing, after resizing all the lube must be removed from the outside of the case and inside the neck.
When seating bullets you do it the Star Wars Ewok way…Dry with the brass screaming.
I thought a little dry humor would make you remember the correct way. 
Don’t the cast bullet guys use some sort of bullet lube? Maybe that’s where the idea came from.
Cast lead bullet lube and lead .22 ammo is lubed to help prevent leading in the bore, modern jacketed bullets are not lubed.
:rolleyes:
I thought you were supposed to brush the neck to get the carbin out becouse it can let the bullet slip like graphite. I cant imagine lubricating the inside of case necks then.
I think the OP is saying , does he need to relube the brass to keep it from getting stuck like when resizing it. If so,then no you dont. Lube is for the resizing stage only.
In the past I have had issues with 30-06 if I did not remove the case lube from inside the neck after resizing. I would get a lot more flyers when shooting paper for group size. I also had to adjust the crimp tighter, because insufficient neck tension would cause hang fires with lighter projectiles.
I am a lot more careful about not leaving any case lube in the neck these days when reloading for my Garand. The people at www.accurateshooter.com have a lot of experience with precision rifle, so I am going to take a closer look at dry lube for the case mouth when reloading bolt gun ammunition in the future.
first thing I will say is you don’t want any lube in that seating die. It will eventually gum up the works. If you have been using that die with lubed cases then you need to disassemble the die and clean it well.
I am a little crazy about my brass. I use an ultrasonic because I want the brass clean inside and out and the primer pockets shiny. I then size. Then I tumble in clean media to remove the sizing lube and shine up the brass. that tumble cleans out the necks. Then you have to clean the media out of the primer pockets and flash hole. I have a brass prep station and just use the flash hole deburring/flash hole uniformer to clean the media out. it has all sizes of neck brushes mounted on it so I hit the neck with a brush as the final step.
on my bolt guns I use a lee collet neck sizer no lube is required. saves a bunch of work.
Have you experimented with dry case lube inside the neck and compared group size with rounds loaded without case lube during seating?
I use dry case lube in the neck but I am assuming that my brass cleaning process eliminates it by the time I am bullet seating.

Many competitive shooters do not like cleaning the cases with stainless steel media or any other cleaning method that removes the carbon from the inside of the case neck. And if you read the link posted above from Accurate Shooter you will see why target/benchrest shooters do not like squeaky clean necks.
For the average shooter with a AR15 carbine I think it doesn’t matter, BUT it “might” with my heavy barrel .223 bolt action. My problem is I’m 65, have chronologically gifted eyesight, drink too much coffee and need laser guided bullets.
I just skimmed the article,i will go back and read it. I drifted to reading some other stuff there.
Next time i load some 6mm or 30.06 i will try some of both clean and dirty seems interesting.
This is getting off topic sorta, do you think it would make any difference in pistol (9mm,.45)?
Since neck tension is important in the ar15 , since the bullet can slip forward into the bore during the auto loading process and couse a overpressure kaboom, i brush mine, but in bolt action maybe it could help a bit. Be worth doing some experiments…been shooting a lot on 9mm and now the rimfire again. 100 yard rimfire is the worst addiction ever.
