Re: difference between hard cases?
Both are good but the Storm cases are better than the Pelican.
the 'IM" designation is what you want.
Also, do yourself a favor - upgrade to PE foam from the standard foam. It is what the .mil cases spec and the only type of foam McMillan will ship with their cased rifles.
You can read about the different foam types, order foam to fit the case from experts, and get a good overall price from these guys:

Call them - they are good on the phone about making sure you get exactly what you need. Since you are going to do empty case + foam to get the good stuff (PE), you can order a second or third set of the lower side 2 layers of foam and cut your case for multiple rifles/systems, then swap the foam in about 30 seconds.
Cutting the PE - ignore the advice that says get an electric knife. I used a Boner from Chicago Cutlery, hit it with the steel about every 14 inches of cutting, and it did a fantastic job.
the Hardigg Storm cases have better latches, better wheels, 2 additional latches on the ends, better protection of the latches, and a tad more interior room. Also there are reports of the Pelican plastic shattering in cold conditions but not of the Hardigg.
I have both, and the Pelican is a nice case, but the Hardigg is way better.
Oh and if you find yourself on that 200+ page thread on BARF.com re: foam cutting, every bit of that is about cutting the standard foam, which I recommend you pass on. You can reference that thread for equipment layout if you want, but no need to build a hot wire cutter for PE.
