Airforce Anyone tried a .458 copper round in a .50 sabot in the .50 texan?

So I have some .458 250 grain lehigh defense copper slugs. I have .50 sabots. The sabot with the slug in it measures out .510 or damn close. Anyone try this combo before?
I got some .451 lehigh stuff also and it's a little too small, but I have .457 lead that works great in these sabots. I'm wondering if the extra .001 matters or if copper will act very different?
Anyone do this before?

Some videos have shown tht a saboted round is fairly accurate. All you can do is try. .001" is pretty small. There's likely that much variance in thickness on the petals on the plastic sabot. Another thing to do to take up space is annealing the copper. Annealing copper softens it some and expands it as well.
