To be sure, post make, model & caliber of firearm...make,style, model # of rings if available. Some firearms, for example, have an extra long bolt throw, and would require a higher set of rings.
Someone may have the exact setup and provide personal experience.
You should be able to go with low rings even though medium would be fine. I use the low Leupold rings on all my Remington 700 rifles and most have a 3-10x40 power scope on them. I like to have the scope as close to the bore as possible without toughing it.
Its always best to have your scope mounted as low as possible. Helps you come to bare and get it in your eye the fastest. If you can mount the low's then it would be best so that your cheek weld will be right on.
The gunsmith looked at my set up and just told me that I will have to go with the medium height leupold rings as the power ring on the Weaver Grandslam will be tight against the bases and won't turn with the low mount. Thanks everyone for your input.
First of all, if you haven't gone winter backpacking, it needs to happen in the near future. It puts a very unique twist on the summer version of the activity. Yes, it's cold but it's nothing that being prepared can't remedy. Beyond it's therapeutic and recreational value, I think it is a very good tool for the big game hunter as well. I don't think that you can spend too much time getting to know the ins and outs of the area that you hunt. And there is no better way to gain experience in...
