I tumble the empty cases, load, and, anything that required lube gets tumbled again. There is no problem cleaning loaded ammo in a vibrator tumbler.

Somebody recently posted here that they had tested that theory via tumbling ammo over differing times and then shooting over a chrony to find velocity deltas associated with higher pressures. IIRC, their data showed no velocity increases over several hours of tumbling.but the possibility has been brought up in the past that if the powder inside the round shakes enough to act as a self abrasive and go to a finer consistency, then you may increase the burn rate and get higher pressures.
That's PROBABLY true, but the possibility has been brought up in the past that if the powder inside the round shakes enough to act as a self abrasive and go to a finer consistency, then you may increase the burn rate and get higher pressures.
I was talking about rifle. I do the same with handgun. I enjoy loading but I don't have much time for it & I rather be shooting then cleaning brass. If by some chance I can ware out those really hard dies then they have already paid there self off.I like your style. A little powder residue never hurt anyone.
I guess this is where you start to see who reloads to shoot and who shoots to reload. At least for handgun loads. Rifle is a different animal.
Tumbling loaded ammunition is a DANGEROUS thing.
Not because a bullet may ignite the primer of another round in the tumbler.
Powders are milled to a specific size and shape then sometimes coated with inhibitors to achieve a specific burn rate. When powders are tumbled the size and shape of the individual grains breaks down into smaller shapes and sizes resulting in a faster burn rate with more pressure and power being released faster when ignited!
Tumbling loaded ammunition changes the powder load from one known thing to another unknown thing! The load grain weight will remain the same but the surface area will dramatically increase as will the burn rate.
This is how re-loaders and guns get hurt! Don't do it!
This is just what I've been told and assume from my experiences.
JCHow does one spend much time cleaning brass, I toss mine in a tumbler and let it do its thing while I'm in bed asleep.
Maybe I'm just good at multi tasking.
I like the laid back also & hope to get back there soon but for now I chose to spend these few seconds talking to you instead of cleaning brass.
