Your best off trying a bunch of different slugs and find the one that likes your particular shotgun best. Brenneke slugs are usually a good option for a smooth bore. Remington Buckhammers work good in smooth bores if you can tolerate the recoil. For deer manage and reduce recoil slugs are probable sufficent. Remington manage recoil slugs work great in my Rem 1100.
I would also suggest asking your question over at Shotgun Worlds forum. There is a sub-forum for slug guns and several very helpful and knowledgeable members.
