BTW, I got my 2nd order of this stuff yesterday.

I'll put up a picture later, cause it is pretty damned cool.

10 cans of it, plus some other .22lr we had from my wife's 10/22, now I'm sitting at about 6500 rounds.

I got a hold of some lapua trainer rounds a few months ago and they were so greasy they wouldn't even chamber in my 15-22 or my dads browning pistol.

Just run em through the dishwasher, that will make your significant other happy.

The grease or oil on the bullets is lubricant which contributes greatly to accuracy. Clean it off and they will no be as accurate. I have shot some sk ammo with that oily lube and a lot of wolf 22 with it. Both are very accurate in match grade rifles. I would not remove it.

Try shooting a few groups with a garden variety 22. Then shoot several groups of the SK. After 2 or 3 groups you will see an improvement in accuracy as the barrel gets the new lube in it. Then go back to the previous brand 22 and the accuracy of it will be improved until the "oily" lube is shot out. I've seen that happen several times with match grade 22 rifles.

Interesting ... but then again, it's been about several years since I last shot any Lapua.

I registered to this forum only to address the issue of tumbling live ammunition.

1) Will tumbling activate/ignite/fire my ammunition?
No, it will not if you're using your average vibratory tumbler

2) Will tumbling alter the burn characteristics of my powder by "breaking" down the powder granules?
This is almost a definite no. popnfresh on the ar15.com forums ran a stress test, 200+ hours of tumbling and powder inspection under a microscope. He tested different powders (except for extruded): Winchester 748 (ball type), Alliant Unique (flake type), Alliant Power Pistol (flake type), AA No 7 (ball type), FFFg (flake/ball type?), Bullseye (flake), 1680 (ball), 2230 (ball). In a lyman turbo 2200. All with no significant change in the powder.

It's still up to you whether you want to tumble live ammo or not. (almost all manufacturers state you shouldn't to remove liability). Many people do tumble live ammo with no problem. I've tumbled .223 and .45 auto without any issues (extruded and flake powder).

The lube, regardless of what kind it is, is on the ammo for a reason. Originally it was done to keep the bore from leading up. So in my case I leave it on because then when I clean the gun I can use a dry boresnake on the barrel and that is all it needs. Also why they tell you when testing ammo to shoot up to 10 or more bullets of the new variety before running a group thru because you need to replace the lube from the previous ammo with the one from the new ammo you are testing.

Then why isn't all ammo oil covered?
