Tumbling loaded rounds?

[Paul "Fitz" Jones]

Agreement with previous post

It is the reloader with a vibratory brass cleaning machine cleaning lube off his loaded ammo that forgets to turn the machine off after say 5 to 10 minutes and leaves it for hours that can damage the powder granules in my humble opinion.

My main interest is in making every loaded round identical in every aspect in a large lot so that every round will have the same point of impact no matter when fired. I will admit it can be a tiny factor but the length of time that live ammo is vibrated or tumbled should also be consistent and if a batch is forgotten for an hour or more and that batch is mixed in with the lot of a thousand rounds that is being created as an identical lot, could they possibly be flyers from having a slightly different point of impact?

Create Indentical lots of a thousand Rounds
Brass of the same brand and lot numbers
Powder of the same lot numbers
Ball powder that meters more accurately
Primers Federal Or Winchester only
Bullets of the same weight and hardness
Loaded in the same conditions for the entire lot
Stored in a temperature controlled environment til taken to the range in an otherwise empty large ice chest.
A small ice chest carried and placed under your shooting position protected from direct sun rays to control its temperature.

Different temperature controls are needed for very hot summer days and very cold winter days.

No problem for 15-20 minutes to knock the lube off.

Usually with rifle rounds.

Mr. Paul "Fitz" Jones,

It looks like you ve got the procedure down for loading match grade bullets, but for pistol ? Seems like an awful lot of trouble to me. The average Joe will be lucky to shoot his pistol at 50 yards.

Most of the shooting happens at 25 or less, I cant see that the attention to detail will matter to an average shooter. I will admit my procedure is much like yours for shooting big rifles at 600 and 1000 yards where it makes a difference.

On a 25 yard bullseye, in competiton, I seen many people win with a whole lot less effort. Same goes for PPC and IDPA. Fact of the matter is most people cant shoot well enough to realize the small gains in accuracy due to the extra effort.

With This logic ALL the Factory Match ammo, or just target ammo for that matter, that travels from a factory on a truck that vibrates for hundreds if not thousands of miles in back of a truck has to travel the same distance using the same speed (MPH) and use the exact lane choice so that all the bumps are the same so this simulated tumbling action can be to ensure the match ammo is all uniform and the performance, burn rate, POA etc, is affected. IMO, I think NOT.. [A simple experiment will show that driving with a bucket filled with tumbling media and brass will be polished by simply placing the media and brass in the trunk of a car or in the truck bed of a pickup. Try it put a 100 or so cases, tie it down so it wont move (to prevent any dampening) and over the course of a tank of fuel or two, you will have polished cases. The bumpier the route, the better for best results, however thats not my point...............................] To sum it up, The point is, that ammo shipped via truck, car, etc is just as much, if not more vibrated/aggitated (IE: TUMBELED ) than a few minutes or a quik clean up with live rounds in a tumbler.
One could argue that ammo being shipped is not touching each other on this journey from the factory because its boxed up for commerial sales. However there is lots of ammo that is shipped loose in a box or in ammo cans and free to move and bounce around along its journey.
I know this thread is Old however I felt like commenting and brought it back to life. My.02 cents has been spent, and IMO spent wisely.

I tumble all of my rifle ammo after it's loaded to remove the lube.

I don't put live rounds in my case vibrator! I have heard that it is possible for the powder inside the case to be affected. Something about the coating possibly being damaged and thus changing the burning characteristics of the powder.

Internet myth.

Wow, a 9 year old thread resurrected. That may be a new record.

Zombie thread, rises from the dead! But I tumble my loaded rounds too, still here to tell about it. Sure makes 'em perty.

 

[blarby]

Mmmmm.......puuuuurty tumbled

 

[XxBulletBendeRXx]

Old threads never die.......

they just are on hold for a long while at times..... I thought this was a good topic to dig back up!! Why the Heck not!!! ?

 

[Arkansas Paul]

Them sure are purty rondog. I too, toss em back in for a half hour or so.

 

[FROGO207]

Those rounds now have your finger prints on them you know so you better put them back in for a while longer to get rid of them prints.

I polish my finished ammo with a bit of Nu-Finish car polish to keep them looking like new for ever.

i just wash all my brass in hot soapy water after sizing. i tumble prior to sizing, so it works well for me.
