M ammo Posted February 25, 2014 Share Posted February 25, 2014 Loading 308 cleaning brass using the stainless steel tumbling method. Just putting this out, to see what you folks might think,, I have been cleaning my brass using the Stainless steel dawn Lemi shine method, it works well and cleans up brass that you would have otherwise put in the trash. My question is. Do you think it gets your brass too clean? Squeaky clean? To the point That you might lightly wipe it down with some type of lube, after re-loading it? So that it cycles in your rifle better? Link to comment Share on other sites More sharing options...
bigedp51 Posted February 25, 2014 Share Posted February 25, 2014 You should NEVER lube your ammo or leave oil or cleaning solvents in the bore, it doubles the bolt thrust which can damage the rifle. Link to comment Share on other sites More sharing options...
gatnfans Posted February 26, 2014 Share Posted February 26, 2014 If you feel you need to do something put it in your dry media tumbler that has some brass polish (whatever you use) for 30 min or so and it will be fine. I wet tumble and don't see the need though. Link to comment Share on other sites More sharing options...

I wet tumble and don't see the need though. That is another thing I’m fishing for and wondering if someone will, jump in and say something, Polish.. lots of different ways to shine up brass, and yes that leaves something on the brass, that goes in the chamber. So when I say lube, I’m not talking about glugging in 10-w30 Break free put it on wipe it off, it leaves a coat a slippery coat. Someone is doing something, and I’m just asking the question. Maybe not asking it well, But putting it out there and see what I learn. Link to comment Share on other sites More sharing options...
Steve RA Posted February 26, 2014 Share Posted February 26, 2014 If the case is "slippery" when fired it will not grip the chamber walls - as it should - and will transfer more rearward energy to the bolt/locking lugs which isn't good. Link to comment Share on other sites More sharing options...
deerassassin22 Posted March 9, 2014 Share Posted March 9, 2014 Also will gather dirt if you but oil on your rounds especially in a dusty/dry environment. Link to comment Share on other sites More sharing options...
M ammo Posted March 11, 2014 Author Share Posted March 11, 2014 Factory ammo has something on it. you can feel it. it may not be Oil,, but it is something... I wonder what it is. Link to comment Share on other sites More sharing options...
polizei1 Posted March 16, 2014 Share Posted March 16, 2014 I spray my cases with Hornady One Shot while the cases are in the casefeeder. The stuff dries VERY quick, I've never had an issue, and never wipe down or re-tumble the cases. A little bit goes a long way! Link to comment Share on other sites More sharing options...
RPatton Posted March 23, 2014 Share Posted March 23, 2014 The case is supposed to grab the chamber and offset the thrust vector reducing the force applied to the bolt. In a semi auto the round is being pulled out of the chamber while there is still pressure in the case. Brass ejected from a semi-auto hot due to the friction caused by that pressure. Brass from a bolt gun is not hot no matter how fast you eject it. Lube on a case is not a good thing. Steve RA is correct. Link to comment Share on other sites More sharing options...
2011WRBSTI Posted March 29, 2014 Share Posted March 29, 2014 (edited) Instead of starting a new subject just for this picture.......,and since it is along the lines of prepping your brass......when you get 308 military brass for free, in an F15 flare crate, it is important to look at the primers before punching them. I punch primers before I wet SS tumble my brass and didn't catch the first one of these and admittedly was on a bit of auto pilot not paying too much attention to the pressure I was applying.....what harm could come....I'm just punching primers out always pay attention End Result Edited March 29, 2014 by 2011WRBSTI Link to comment Share on other sites More sharing options...

M ammo Posted March 31, 2014 Author Share Posted March 31, 2014 When I say Lube, ammo I’m not talking about dipping them in 30 Weight oil and stuffing them dripping in the magazine. What I did try is laying out my 308 re-loads and spraying them with Remington oil with Teflon thin long lasting film. I let it sit for a bit and wiped them off. I clean my rifle with this stuff. the chamber too!!!!!! So how much difference does it make? The gun ran fine, no hang up, or exploding from pressure. So far so good.

bigedp51 Posted April 1, 2014 Share Posted April 1, 2014 (edited) A cartridge case, the chamber and bore should be free of "ALL" oil or grease! How many warnings do I have to post from the firearms industry about not lubing your ammo. If anything keeps the case from gripping the chamber walls the bolt thrust is doubled. A military NATO requirement is for two proof pressure cartridges to be fired, one "DRY" cartridge to proof the barrel and one "OILED" cartridge to proof the bolt and receiver. After proofing the firearm is checked for headspace and if the firearms has too much bolt setback the firearm fails proof testing. Bolt thrust is the major cause of the headspace increasing on a firearm. Below when you pull the trigger the firing pin pushes the case forward until the shoulder of the case contacts the shoulder of the chamber, then the cartridge goes bang. Then as pressure builds the primer is pushed out of the primer pocket, as the pressure increases the brass then stretches to meet the bolt face. Acting this way the case acts like a shock absorber and reduces bolt thrust and dwell time the rear of the case is in contact with the bolt face. Think of lubing your cases like your in the boxing ring with Mike Tyson and stupid enough to leaning into his right hook. Now think of a dry cartridge case and ducking under Mike Tyson's right hook and then running out of the ring to keep him from biting off your ear.

BitchinCamaro Posted April 5, 2014 Share Posted April 5, 2014 Is cleaning as much of an issue with pistol pressures? Admittedly, I almost never clean the sizing lube off my 9mm rounds. It's a thick one too- Hornady unique paste. Link to comment Share on other sites More sharing options...
Steve RA Posted April 5, 2014 Share Posted April 5, 2014 Obviously it can't be too bad or everyone would not be singing the praises of lubricating the cases before sizing. Some tumble after that and some don't. Also the pressures are slightly different between the pistol and rifle calibers most people use. Link to comment Share on other sites More sharing options...
