Yep, I Tumble Bullets.

[Tidus56]

Have you personally witnessed cold weld? I haven't. I've only read about it on the forums. I've pulled bullets from milsurp cans made in the 70-80s. No cold weld. I recently pulled bullets from ammo I made 10yrs ago. No cold weld.

Yes, when I started using wet tumbling I shot some ammo that had sat a year or so after loading and it was shooting faster than when it was loaded. Checked the ammo and it had welded. That's the only time tho

I used to be worried about bullet set back with recoil and now I have another worry,cold weld.
Worries never stop.

I've seen pressure changes over time on a Oelher unit. Pressure and velocity. I cannot say it was from cold weld, but the cold weld idea makes sense.

I don't tumble polymer tipped bullets because of the potential of loosening the tips. Especially on those bullets that don't have a mechanical lock on the tips. On hollow tipped bullets I've seen them get clogged with cob so again I don't tumble those bullets. Just my preference. Dull or shiny they seem to shoot just fine. HBN might help with cold welds. I just don't have the time so I don't worry about it.

I'd be more concerned with introducing an abrasive on to the bullets. Probably fine if fire lapping. Not sure I'd do it just to have shiny bullets.

I will also be worried about deforming the tips bouncing around in a Tumblr

You guys are showing me a whole new area of reloading that I didn't know existed

LOL not for the folks who are interested in accuracy.

I can't say tumbling bullets is a bad idea if you like shiny bullets. I have not taken the time to wash my pickup for over eight months, so I probably won't take the time to tumble my bullets either.

Only eight months I'm talking a couple years! Unless you count the natural occurring rain shower

Mine gets cleaned when the snow melts and slides off of it. I will say that if I drop a bullet on a dusty floor, I will wipe it off on t-shirt before seating it.

This is done for a reason. Most folks do not have rifles that will benefit from this however, for those that do this is good for accuracy because it does remove some of the variables that are inherit with the manufacturing process.

Have a friend who I shot 1k BR with years ago who is now part of the leadership team there. In addition to packaged sequentially right out of the dies they are not tumbled for polishing. Going to give some of these a try. Not a huge selection and yes, they are more expensive but if they will shoot dots then that is what I am about.

When you test them Boss Hoss please give us your opinion on the bullet.

I want to be able to use them on game. They shoot great and are very easy to tune in my rifles. I've heard mixed reviews about on game performance.

Can you explain what variable is removed by tumbling?

Can one of you previous posters tell me how you know a projectile is 'suffering; from cold weld? I know how hard it is to use inertia hammers to seperate a bullet from the case (milsurp ammo). But I have no way to measure this so called 'cold weld'.
FWIW since reading about the dangers of 'cold weld' I now use graphite before seating my rifle ammo.
