Sounds cool. I saw a pretty neat conversion from a 28 gauge Sabbati to a 33 Winchester the other day. It also had a single selective trigger. Owner claimed it shot 3" at 100 yards and loved the trigger. I did ask if he had ever used it, selectively, and he said no.

It was built by some guy in Idaho. Can't remember the name but seemed like a neat rifle. They had a lot of trouble with the regulation. He said it took about 100 rounds to dial it in. The 'smith ended up making a jig from a picture in a book to finally get it correct.

Good Luck with it.
