The T3 is a good gun but really nothing was improved over the whitetail hunter. The T3 represents Beretta's way of reintroducing Tikka to the U.S. Stoeger, the previous importer, did not have the marketing muscle that Beretta does. So they created a new stock and cheapened the gun a bit by incorporating a 1 size fits all action.
The gun is really not that much different than the whitetail except the stock.
If he wants a whitetail, I have one for sale in the classifieds with the best mounts/rings(100$ price) you can put on a tikka thrown in. The yare much better than the cheapo mounts the T3's come with.
