Thanks Joe, as always informative and entertaining. I've owned a few of the scopes mentioned and agree with you opinions of them. I have a Konus Pro that I bought for my Savage 22 and didn't like it. When I bought my Diana 48 the Konus was on the shelf so after trying my spare Leupold (wouldn't focus close enough) I installed it. It lasted less than two weeks, junk scopes IMO.
I've had a Mueller on my Savage 22 for probably 10 years and it's been a good scope, it's clear and tracks well. After my Konus fail I bought a Mueller 8-32 X 44 with a mil dot reticle, so far it's been flawless too.
I don't know about the newer Redfields but the old ones were great scopes. In August 1977 I was 16, having been saving my money I bought a new Winchester model 70 in 30-06. A month later I bought a Redfield Widefield MS 3-9, it's never let me down and is still on the rifle. The rifle cost $217 and the scope was $156, a lot of money in 1977 to a 16yo farm boy.
