RE: Muzzleloader scopes
You are looking at some fine scopes. They both are very good. One (Elite) gives you Rainguard option - the other (SII)gives you an extra inch of eye relief. Both have clear glass - both good low-light optics. Don't forget to compare weights - compare bothscopes back& forthsliding room from turrett on-back. I think both have a very good replacement warranty.
I know the Sightron websitegives a nice breakdown in inches for their entire lineup of scopes. I'm not sure if Bushnell's website does also.
