You can use rifled slugs with a full choke, but I doubt they will work very well. It will not hurt your gun though, the fins on the slug are made to crush as they go thru the choke. Full chokes with rifled slugs usually are not too accurate because of the amount of damage they do to the slug as it leaves the barrel.

I would also suggest an Improved Cylinder or Modified choke. And you should be able to shoot farther than 35 if you have to, probably 50 or better of your gun likes those slugs and you shoot well.

Those slugs are fine for deer, if you don't want to damage that much meat don't shoot them in the shoulder, aim for the vitals like you would with a bow. Don't be suprised if they run though, using that big ole slug doesn't mean they will drop on the spot. As a matter of fact I haven't had one drop yet, they all run for a little ways.

Like said above, slugs are not as devastating as a high powered rifle. I shot one last year with a full bore slug that weighed 600 grns. It punched a hole all the way thru the deer about the size of a quarter. The exit wound was about the same as the entrance wound. I shot the deer from about 20 yards.
