Thoughts on rechamber

[Robmill70]

I have a Ruger #1 in 458 Win Mag and was thinking of reaming it 458 Lott. Thoughts and anyone have experience doing it?

It is the easiest rifle to convert to the 458 Lott, since you don’t have to worry about feeding issues. Also I feel the win mag reamed to Lott gives you a better chamber, as the win mag has more free bore.

The .458 Lott chamber with the .458 Winchester long throat maximizes the application of high tech monolithic bullets by allowing the longer bullets to be seated out further thereby preserving case powder capacity.

No real reason not to.
Even if you don't have it stamped or engraved as a Lott, 458WM will shoot just fine in it as well.

I handled an OEM Ruger #1 chambered in 458 Lott and I wouldnt shoot that with some elses shoulder, let alone mine! Then again I wouldn't shoot that rifle in 458 wm either.

No real reason not to do it. I would also strongly recommend adding a ton of weight to the gun while you are at it.
