Sure, but does the extra power of the Lott shoot to the same POA?
Still, I suppose you could still use WM ammo.

Then we are back to "if everything comes out right."

The pigs Tom the pigs are alwas worthey.
Why are you re clocking the barrel?
Good grief I agree with JPK.

If you rechamber a barrel and every time you do it you come up with where the iron sights are still on as far as the horizontal with perfect headpsacing and freebore, I guess you get a prize. The prize I got is your comment because it should go in HUMOR.

Going from one similar chambered round to another in the exact same barrel and rifle with a reamer and crossed fingers may or may not yield results you like. Cross your fingers if it makes you happy. I'll bet on a good chance of more fiddling than you planned on before you are done and it's done properly.

Tom,
Where in the Republic of Texas are you located that you canâ€™t find a competent gunsmith? The conversion of a .458 Win Mag to a Lott is one of the easiest of conversions. The biggest problem is magazine length. You donâ€™t have to take the barrel out of the action. The sights will be right on as the difference at dangerous game ranges will not be noticeable. Most rifles do not have excess â€œfree boreâ€ that is an old Wherbey practice. My Lott will accept both the 550 and 600 gr bullets loaded to 3.310 over all length.

I find mine in my own shop near Dripping Springs. TSJC student and only do work for myself. Mechanic and machinist buy paid trade. I've seen lots of buggered up jobs where people buy a mail order reamer (or other project part) and expect the rest to do itself. It doesn't work that way and different people have different degrees of tolerance for error and different tolerances for different tolerances in various directions. I like to pick mine up front, not buy a reamer and reckon it'll be OK however it comes out. Everybody is different. If people want to crucify me on a forum called Accurate Reloading for suggesting doing everything possible to make sure a rifle is as accurate as possible that's more their issue than mine. I shall bid you adieu.

Tom there is no way we can crucify you because different people have different degrees of tolerance for error and different tolerances for different tolerances in various directions. We just canâ€™t get our tolerances for different tolerances in a row so we canâ€™t build a cross.

The easiest way to get your iron sights to be clocked right if you do take a barrel out (why you would for such a simple job as converting a 458 to Lott I donâ€™t know) is to put a â€œwhiteness markâ€ on the bottom of the barrel and the receiver when it lines up the sights will be right.
