I too vote Burris... Fullfield II with Ballistic Plex reticle in either 3-9x40 ($200 from
SWFA.com or 3.5-10 x50 for $300. There's also an illuminated reticle version of either scope for another $100 more.
I have one personally, the 3-9x40 version, and I absolutely love it. The optical quality is as good as any scope I've ever looked through, including the Tasco Super Sniper and an ACOG. (well, maybe the ACOG was SLIGHTLY brighter
)
CB900F, sorry to hear about your problems with Burris... all I can say is that mine is absolutely excellent. Not happy about your Customer Service experience though... That "lifetime of the scope" warranty was a big plus for me. You're not the first person I've read that didn't like their Burris compact though... I did much research before buying this one, and found MANY happy owners of this particular model, and not one single negative comment.
Ballistic Plex reticle:
Using the Ballistic Plex reticle with a .223, you are "on target" at 100 yards, same at 200 yards, 1" high at 300, 2" low at 400, and it drops WAY off to 11" low at 500, which you didn't mention anyway. SO out to your stated 400 yards, you are on target all the way out.
BTW, the 500 yard line of the Ballistic Plex is not nearly that close to the edge... It looks much more pronounced in the factory pics. Here's the real thing:
Good luck with your selection.
