I've got Aluminum on all my guns except my 300 ultra mag....that one i put steel on. But i'm sure it would hold up with aluminum rings as i have them on my wsm and have not had a problem with them creeping what so ever! I also use rosin on my rings which makes a world of difference!
I like and have steel on all of mine. However I don't see any drawback to aluminum though. I've never used rosin on the inner of my rings, but it sounds like a very worth while technique. It's important to make sure that your rings perfectly are parellel to each other and that your base screws are secure tight.

I've always just made the ring screws snug (don't want the scope tube getting distorted) and the base screws firmly hand tight. I've never bothered to invest in a Wheeler toque driver. I just use a few good basic tools when I've mounted my optics or those for friends. Tools like those Torx and Hex drivers from either Bondhus or Proto. I have some specializes tools from Leupold too. Also found that if you spray a degreaser on the screws and in the holes, they tend to hold very well without working their way loose from recoil over time. Always worked great for me since I've never had to use Loctite.
Every year my Pro-Staff and I head to the woods to hunt the old wise Tom. We travel thousands of miles covering numerous states hunting these old guys. Lots of times we end up hunting public lands or private property that have been hunted already. That’s the last thing you want to hear when you just traveled 6 hours that someone else has already hunted the property. We had to come up with a game plan and one real fast.
The first thing we did was ask the farmer were they usually see the birds in...
