Just an update.

I have found a decent load:
Chronoed at 2450 fps and getting just over an inch grouping at 100 yards with a fixed 3 power scope. I think they would be more accurate with a higher powered scope.

I'm taking two rifles with me this weekend for deer:

CZ 550 458 lott hogback stock, polished and tuned for smooth function, Leupold FX-2 3 power big bore scope with German #1 reticle, Speer 350gn at 2450 fps zeroed for 200 yards
The 458 lott will be for more open areas or breaks in the patches of trees, ranging from 100-250 yards.

Puma 92, 357 mag, 16" barrel, tuned and polished like glass, factory iron sites, 158gn Hornady XTP at 1500 fps.
The 357 will be used when we walk a line through the denser brush and trees, typically 50 yards or less.
