The Bushnell Elites are some of the best. The 4200 model tests out at 92% in brightness and is as tough a scope as money can buy.
I hear good things about Sightrons as well. I don't know if they make any that fully multicoated, but they, along with the Elite 3200's have a solid rep for performance and being reliable. E

I have a Bushnell Sportview, their cheapest scope, it's a 4x12x40 with AO. It has been on my 22-250 savage for about 9 years, it works great shoot groups in the .3's

Odd, I had a Bushnell Sportsman 3-9x on a 22-250 briefly. Also shot into the .3's some though mostly in the .5-.6's.

Sightron's are great scopes in everyway except the coatings. Real shame too, they have a winner otherwise.

Buckmaster, and Elite 3200's have nice glass, pretty good, not great coatings, and the same internal mechanism as the top of the line models. I likely would go with the 3200 just for the Rainguard coating. Weaver V-series are worth looking at too. Slightly lesser glass(I think), but full multi-coating(the above are very good single coatings) and good mechanisms.

Also if 3-9x would work for you, I think the Leupold Rifleman series looks worth investigating. Though I haven't had one mounted to try myself.
