I put the longest one on mine, and at the moment I can't recall what it was. The Sweet 17 was made in three sizes and I took the one that magnified the most. My son currently has the rifle so I can't take a look.
Added later: The Sweet 17 is 6X18, the Elite 3200 is 5X15. It took a lot of looking to find one of the BSAs that was clear out to the edges, so this wouldn't be ideal to mail order. The Bushnell is a much better scope, and cost three times as much. It sits on a 17HMR contender barrel and the combinatiuon works great.
