As you no doubt know, Larry, sonic shock was worse for the loader [of recoilless rifle] than for the gunner because the loader faced the tube which put his ears in line with the shot and the backblast. When I was the loader, it seemed to be about the closest thing to "hot noise" I'd ever heard.

I've gone from a mixture of 3-in-1 and Vaseline [RIG lookalike] to Mobil 1 20w50 as a hingepin, hook, rulejoint knuckle and lockbolt lube. May try that Mobil grease. I also like IMR7625 for loading 16 ga., Justin.
