Here are my Express rifles - a 7mm Mag on the top, a 416 Rigby in the middle, and a 30-06 on the bottom. I think they're beautiful rifles. I had to do a lot of searching to find the 7mm Mag and the 30-06. They just don't show up for sale all that often, except for the 270's, which seem to be a bit more common.
I thought I was going to have to sell the 7mm Mag recently (I posted about it here http://www.rugerforum.com/phpBB3/viewtopic.php?f=4&t=159015), but I figured out a way to keep it by selling some scopes to raise the cash I needed. I figure that scopes will be a lot easier to replace down the road, even though I had to sell them at a loss while I would have been able to sell the express at a profit (hopefully).
To answer your questions:
1. What is the accuracy like? I've never shot the 7mm Mag because it was supposedly unfired when I got it and I'd like to keep it that way, though I may break down and shoot it someday if I'm able to keep it long enough. The 30-06 has average accuracy, but I haven't tried very many loads in it yet. The Magnum rifles are known to be more accurate than you'd ever expect them to be. I have yet to shoot mine. I just got the 416 this spring and I've only recently acquired some brass, dies, and bullets. Factory ammo is quite expensive of course.
2. Do you wish they were still being made? I wish Ruger would make
me a few more! I'll take one in just about any caliber you can name, but I'd be pleased to find the remaining factory-produced calibers. One in 300 Win Mag or 338 Win Mag would make me very happy, and I'd be overjoyed to find one in the elusive 25-06. I don't know that I'd want them to be back in regular production, because that would probably lower the value of the ones I already own. (Selfish, I know...)
3. Likes? There's a lot to like with these rifles. As I said in that other thread, in my opinion, they are the best-looking factory rifle ever produced by Ruger. I love the integral quarter rib, the barrel-band swivel stud, the multi-leaf express sights, the Circassian walnut stock, the ebony forend tip, the blued bolt handle, and the high quality of the bluing in general. I mean, that's a beautiful rifle! Just try to get those features on a custom gun for less than $3K.
4. Dislikes? The integral quarter rib can make mounting a scope a bit of a pain. You have to mount them higher than on a regular barreled rifle, because the objective bell cannot follow the contour of the barrel where it normally dips down after the chamber. That's why none of mine wear scopes yet. But the iron sights are excellent of course. Someday I'll get something like 1-4x20 or a 2-8x32 mounted on them with Warne quick release rings; something where the objective bell is small enough that it won't cause any problems.
