I think the 50s 99R must have been Savages response to the Model 70. I (stupidly) passed on a nice 50s R in .250 that weighed in at something short of a Sherman tank. I couldn't figure out where the extra beef came from. On the other hand one of my prized possessions is a very nice circa-1933 R. And it doesn't seem any heavier than a 50s vintage EG.
