Best lube for sizing greatly oversized boolits???

[dsh1106]

I have sized a 287405 which dropped from the mold at .290 down to .280 to fit my M77.

The lube groves on the 287405 are the same diameter as that of the 280468. It took three passes, 1 @ .287 1 @ .284 and then .280. Make sure you check on the 1 sizing operation. I had size nose 1st on the 2nd and 3rd operations.

Try Hornady One Shot.

This is what I use for sizing, though again I haven't done that large of a diameter change before. I found it provides just enough slickness to make resizing a snap.

Thank you dsh1106....I have resigned myself to the fact that three steps is likely the best way to do that much sizing...I had hoped to get away with two, actually even one in the very beginning, but I think three is going to be the "right" answer.
FWIW: Lee Precision has a piece of equipment that is broke down right now, so custom sizers are going to take six to eight weeks until they get that piece of equipment back on line.....

The Lady answering the phone, the Lady with the sweetest voice on earth, briefly mentioned the details, but it was more than this old mind could absorb in the couple of minutes we talked.

Thanks for all the kind replies....."muchly" appreciated! ( I strongly suspect the term muchly appreciated is 10X greater than greatly appreciated.)
The ready reference of hundreds, if not thousands, of such sharp minds, with years of experience, is really hard to beat. I for one am thankful for such a brotherhood. So a big Thank You to all of you.

Respectfully, Russ...

If you have trouble finding the Bag Balm give STP Oil Treatment a try. That stuff is super slick.
I had a bunch of 303 British Enfield cases that had been fired in machine guns, WWII tolerances most have been extremely generous. STP was my last resort and allowed resizing without pulling a rim off. the other "commercial" lubes I tried were all lacking....the STP allowed easy in and easy enough out that I didn't think the rim was going to pull off.

Panlube first, then size as usual.
With the grooves filled they wont distort under sizing.

This, fill the grooves first. I've sized from 326 to 314 in one step but definitely need the grooves filled.

Personally I would rather trade or simply re-cast to the correct size.

You can also get Lansinoh HPA Lanolin in the baby aisle by all the breast pumps.

Geeesh! The things we learn as we go through life!
I have never as much as heard of that before, although I do use Anhydrous Lanolin in several things I do / use.
Gotta look this stuff up.

Thanks a bunch.
