Now, I've seen guys use big ol rings on weaver mounts on their pre 64's and you might as well be running a one piece picatinny mount if you are going to run those big azzed rings. Just my opinion of course, take it with a grain of salt. So after years of trial and error, I've came to the conclusion that the weaver style mounts work the best on an H&H rifle, with smaller solid rings like the Burris Zee rings. This set-up allows for all the clearance in the world, you don't obstruct the loading port, so feeding and ejection are 100%. I have set-up all of my m1917 sporters in this fashion as well. Its a tried and true mounting solution that is rock solid and good looking as well:
Of course "YMMV"... I hope you guys had a great Thanksgiving
