tobnpr- Depends how small your aiming at. I do it because I feel as I seat bullets I get more even neck tentsion.

Cold or contact welding
Cold welding of similar metals (bullet & case) may be a problem if all lube is removed from the neck area? Should not be a problem if shooting the reloads in a day or two. Long term storage may be a different story?

I agree neck tension is important enough for even me to pay attention to...
Our targets are about 1-1/2 -2 m.o.a. at 585 and 1000 yards. I was ready to order a set of Redding bushing dies for all our long-range chamberings (7-08, .308, and .260) and realized the bushings are brass-specific, and that each "batch" of brass could be different, requiring sorting- and different bushing sizes for even the same caliber. I'll make the effort at some point when schedule allows more time. Work load allows precious little time at the range as it is...and I HATE load development...but it's a necessary evil. I'd just rather "shoot".... With two sons that I need to load for as well, it's a couple of evenings-with a progressive nonetheless- to get 300-400 rounds loaded with any degree of precision. Hopefully I can find the time soon to spend on accurizing the loads further. Bart's comment about lubricity in the neck affecting tension got me thinking. Hornady's One-Shot does not affect powder, but I do wonder about neck tension. Fact is, I need it for FL sizing; and my guess is that as long as there's some level of consistency to any "effect" from the lube in the neck there shouldn't be an issue. After all, everything about accuracy, from the rifle to the ammunition, is all about the "C" word.

tobnpr- You sound like your in my shoes. I have no kids left that shoot,but I do go through about 300 rounds every weekend. I do all mine on a single stage press. I have been told by my wife ( she misses me ) that I spend about 2 to 3 hrs a night after work on bullet stuff. It's a vicous circle around here. As for lubing the neck, I use a Q Tip and RCBS lube. My brass all goes for a 2 hr tumble after they are sized any how. Then I just put the neck brush in a drill and fly through about 100 every 5 maybe 10 minutes. I never used to do that. I decided once to give it a try and right away I started feeling, as I seated the bullet that my effort to seat them was the same. As to if it helps with accuracy- Jury still out on that one. I have to believe it does somewhat.

A "smidgen" of all the right stuff is OK!!!!!
I need to renig a little regarding my earlier remark 'Tis my opinion the only thing that should touch the inside of a sized case neck before the bullet goes in is a charge of powder and air. Nary a smidgen of lube on the inside of the case; anywhere.
Sierra Bullets sold hundreds of thousands of 30 caliber match bullets that were virtually packaged as they came out of the final forming machine. They were coated with a thin film of lanolin based sizing lubricant. That lube was normally cleaned off and the microblemishes of coin, cup, draw, heel, coring and pointing the jacket to final shape, put in sawdust filled rubber lined concrete mixers to make them shiny bright then packaged 100 per green box. Those dull colored greasy bullets were packaged 1000 per plain brown box with hand written info on it then sold direct to competitive shooters at the larger rifle matches. Those bullets shot 30 to 40 percent more accurate than what they sold in green boxes. That's because as 10 bullets were grabbed as they came out of the pointing machine then shot immediately in rail guns for accuracy, as long as the test groups were in the ones in their 100 yard test range, the barrel they dumped into was kept there. Should accuracy drop off a little but still within their standards, another barrel would be moved under the pointing machine and to top few inches of the other barrel scraped off and put in the second barrel. Those went to the concrete mixers then to QC where they were measured and visually inspected for flaws then packaged for normal retail sale. So, that thin coating of a lanolin based sizing lubricant didn't harm their precision test barrels. But they won most of the matches and set virtually all 30 caliber records prior to Sierra's move to Missouri when the 1K box sales stopped. I've cleaned the lube off of them a time or two and didn't notice any change in accuracy. That lube seemed to be harmless to barrels and did nothing to improve accuracy. It was just a waste of time to clean it off. Last edited by Bart B.; April 8, 2014 at 03:52 PM. |

I am not sure how a tumbler is capable of cleaning inside a casing, but my L&R Ultrasonic does. It will clean the primer pocket at the same time if you de-prime.

If the tumbler's media is small enough to get inside the case, it'll clean the inside as well as the outside. A friend used water with Joy dish soap and BB's in his tumbler. Worked well outside and inside of fired cases.

So do the currently popular stainless steel pins. Search on threads on the topic on this forum and you'll find lots of pictures of cases looking pretty new inside and out.

I've always wanted to try glass beads used to clean autoparts without damage. They are a lot smaller than BB's and so could conceivably get into the corners. I don't see BB's doing what S.S. pins with tiny square edges can do in primer pocket & inside case corners as picture (9mm brass) demonstrates below:
