That would be a very good choice, imo, unless you are going to do running and gunning up close. Then you would want either a lower power or a secondary sight.
Out to 400 yards, you likely don't need for a FFP reticle. If you have a low variable power optic (like 1-4, 1-6 1-8 or 2-10), you are likely to be at your max setting at 400 and can use whatever markings or BDC in the reticle at range. From 200 in, you essentially have a flat trajectory with easy holds at any power if you want more precision. From 200-400, you can learn your holds, or again be on the max setting and use your reticle. Also, with the Leupold, you can get the BDC turret ring.
