Between me and my dad we probably have 10 BSA scopes. I have a sweet 17 on my savage 17HMR and a couple on my other rimfire rifles. They are a decent scope, some of them you need to find the sweet spot in the eye relief though. Sometimes you'll get a lemon but they are really good about warranty issues. My dad runs the big tactical ones on a couple .308s and never had any problems with them.
I splurged a little on the scope I put on my 700 sps tactical .223 - I highly recommend the Mueller target 8-32x44 if you can get one, I bought mine in the states from optics planet. Huge eye relief, crystal clear, locking turrents, side parallax. My friend has a bushnell elite 6500 on his .338 lapua and I think it is complete garbage compared to the Mueller!
