Dave,
I have that rifle with the American stock. It's taken me about a year now to develop my loads, and get comfortable with it. Now that I have worked out the bugs with the stock splitting issue, and finally have my sights regulated to my load, I love it.
If you just want the Lott chambering, go for it, but I wouldn't shoot too many Winchester cases through it, as it will ring your chamber. Frankly, with modern powders, the Win. mag. is quite impressive. I am getting a consistent 2280 fps. with the Barnes 450 grn. TSX, and that is definitely Lott territory. The rifle gives me 1 1/2" groups at 100 yds. with this load, off the bench, with open sights. It is a handful, but it is manageable. Offhand, it's no big deal.
CZ's, like most modern maufactured rifles, need some attention. Considering that the purpose of these rifles is dangerous game, the action needs some slicking up, the stock definitely needs bedding and crossbolts, and you will probably need to order various heights of front sights to get it regulated, but when done with all this, you will have a world class thumper.
If you purchase this rifle, PM me with any questions I might help you with. Good shootin'!
