Sorry if this topic has already been covered.
I'm a big fan of Leupold scopes, especially the 2.5 x 8 for deer hunting. The size, clarity, and compactness are reasons I like them so much. Those scopes come with a lifetime warranty, which pretty much causes them to sell themselves. I have one on both of my Model 70 Featherweights and another one on my T/C Black Diamond .50 cal. muzzleloader. The one on my .308 had dots ground on the reticle, so it can be held dead-on out to 400 yards (it has another dot for 450, but I don't have a range that far). Most of my deer are taken inside 75 yards and my farthest ever was a head shot on a doe @ 185 yards. I had an M-8 4X Leupold that was on one rifle for 20 years and never needed adjustment. I replaced it with a 2.5 x 8 because my vision is not what it was when I was younger. I gave the M-8 4X to a friend who had a Simmons scope on his rifle that caused his shooting to be erratic at best. After installing the Leupold M-8, he was amazed at how accurate his rifle could be.
I also have a Swarovski 3 x 9 that will go on the T/C Encore I am saving up for. That Swarovski is incredibly clear and solidly built. I had it on another rifle that I sold a few years ago, but decided to keep the glass.
Luck Counts, good or bad
