Tumble Lube and Tight or sharp throats

[mjwcaster]

Just a thought-

Can a throat with a sharp knife-edge transistion remove tumble lube from a boolits driving areas?

I am working on casting for my Springfield XD 45, which has a short throat and a stair-step and cutting edge transition into the rifling.

If I were to design a die to cut lube off of a boolit, or even some lead, this would be it.
Especially on an oversized boolit.

Maybe this could be why some people have more success with tumble lube that others.

Brownell's sells the tool to fix that.

Yes I have the throating 1911 thread bookmarked (andd read multiple times) that has the brownell part number in it.
I just need to figure out what size tap handle to use, if I have one that will fit or what one to buy.

It is on my list of things to do.

I do those a lot cheaper than the Brownell's tool. You need the pilot kit and the piloted reamer. I checked out their basic reamer and the nose is much too small to fit snugly in the rifling, might as well call that one a bubba reamer, that's about what it's good for. I had one here, stuck it down one barrel, wiggled it, shook my head, right back into usps it went.

DougGuy,
Thanks for the input on the Brownells tool.
I have looked at your FB page before. I would really like to be able to say I did it myself, but it may end up better having you do it.
I can bubba-smith with the best of them, but would like to do it right.
It sucks that shipping will be as much as your service.
And I understand, I used to run a business where shipping cost more than the product.
Kind of kills single sales.
