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. Only until recently have I found specific torque numbers for ring and base screws. 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.
Jim Zumbo, Craig Boddington, Ron Spomer and Wayne Van Zwoll are all solid contributers to the modern hunting literature. Through their gifts (both hunting and writing) they make us better hunters. Whether it is letting us learn from their mistakes or by teaching us new techniques,they help us harvest more game. But I suggest looking to the oldies, the fathers of the outdoor writing craft, to learn tricks that you might have not used.
I chose to shoot the 270 winchester because I grew up...
