Someone asked that question last year. You will be find for breaking the law/rules. Another example, you shot a deer, its down, you use it for bait, your again breaking the law/rules, this is coming from them. Check this one out.

Only slugs can be used for bear. Few hundred yards is another hunter who is using buckshot, who happens to shot and injure a bear. The bear then comes near you, you shoot with slugs, and you harvest it. Take it to be checked, they notice buckshot, you can get fined, even if your using slugs with a rifled barrel. Makes no sense to me, and I'm a cop for 8 years, but thats what was told to me by the CO that was present during the seminar last year.
