You're right about Winchester having the same barrel contour with their Express guns. That was my complaint with this .375, the barrel was too heavy, too much metal compared to a .458 or 416. So that's why I chopped and fluted it. It's about right, now.

Had it been a .458, I think it would have been OK.

The CZ is a bigger, heavier gun and my be the better option for .458 Lott. But, I would need to slim down the factory stock to suit my taste, agree with that.

I've not handled their synthetic stock, but that may be an option if it's not too chunky.
