If I'm going to hand prime is there any reason not to do so before tumbling to remove lube? I've read a lot of threads the last couple weeks and see many of the minor complaints about having to dislodge stuck media.
Tonight I sized, trimmed, then tumbled about 50 cases. Mostly because I couldn't help but try out all the new things the UPS man has been bringing me all week. I didn't really have any issue with excess lube (the common home brew) during trimming and deburring. Is excess lube in the primer pocket the reason all the sequences I see have priming (and even trimming) after tumbling or is that sequence just because many use their presses to prime while seating? Edit: .223/5.56 |
| Well newbie here at reloading as well. I listened to a guy at work that said to deprime after cleaning brass. Yeah if you do not get all that media out then it screws up the deprime pin. Not often if you don't shake it out enough. Mainly the issue is 5.56/.223. Handgun brass I have never had any issues. Mainly just dump it over and all media drops out. Think next round for 5.56/.223 will deprime first before put in the tumbler. Only other issue was not knowing I had crimped primers yet found that out quick and decrimped all that shit. |

I don't de-capp then clean. I don't like having the extra step. Some tumbling media can cause de-capping issues (the more course stuff like corn cob) the finer walnut usually don't.
I agree with the other posts. You definitely don't want to tumble empty casings with live primers. Motor |

I don't think it could hurt anything. I've never used so much lube that it even came near the primer and I've never heard of anything yet that's been able to kill a primer, but why take the chance?
If you get corncob in the flash hole AFTER it's been primed, it will just blow it right out. But, again, why take a chance, plus you'll have debris blasting down your barrel. Tumble lube off then prime. |

Ditto, prime after tumbling.
With the media that I use (Zilla desert blend, with Nu shine and mineral spirits) it small enough to pack in the primer under the flash channel, and will cause nothing but ignition problems. 
Hell, even with larger grain media that can not get through the flash channel, you still have dust in the media that can get into the primer past the flash channel to cause the same problem. So first tumbling to clean the case before they every see a sizer (could deprime with just a decapper die only before this first tumbling), the cases are sized and prepped, then back into the medial to remove the lube and clean the pocket if the cases where not decapped before the first tumbling, then loaded (with a final media tumbling of the loaded ammo to remove any finger oils/salts if the ammo is intended for long term storage). |
