I'm no scope expert, but I know that there is more than one model of Nikon ProStaff 3-9x40. One of them is specifically for rimfire.
I went to Academy today to get one for $99.95, but they were out. They did have the non-rimfire version.
Personally, I'm interested now in a Leupold FX1 4x32 or a Leupold VX1 3-7x28. I wish I knew what the relative quality of these two is. i.e., given that they're about the same price, does that mean the glass in the fixed is better?
Any opinions?
Well, it might have something to do with the 4x32 fixed having a larger objective lens, 32 as opposed to 28. Because of that I would guess it has more useful optics. It gathers more light into the scope. I'm not too bright to start with, and I'm definitely not an expert in anything, but if I was picking between those two I'd take the 4x32 because I would guess that it gives a brighter sight picture and requires less light to display a decent image. On the other hand, I may be completely wrong. It would be a little fatter and might not look good on a small .22.
I did some research and sort of answered my own question about parallax. For a .22 I definitely don't want anything with a higher parallax than around 60 yards, and preferably around 50 yards, at least not for hunting. If I was shooting at targets out past 100 yards it would be different. But I don't plan on shooting at any game with a .22 rifle out at 100+ yards.
