My only experience with one was a very early Rem KS 375 H&H that, upon receipt used, I discovered a crack in the area ahead of the trigger. I called Remington (this was '96) and they requested I send it back for their custom shop to take a look. About a month later the rifle arrived with a new McM KS stock gratis. Good job.
I just purchased a Win M70 375 H&H from Erich here that has a Brown Precision stock. I note that the stock (and rifle too) feels great in hand. I also notice that the area ahead of the trigger has a layer of woven fabric (I am assuming Kevlar?) molded in. The very lean forearm has about zero flexibility. Overall I am impressed with how the stock feels in hand with a lean forend and a just right open grip. The stock weighs, all up with a 1" Limbsaver pad, just 22 oz. A solid product without question. By the way, Erich was great to deal with on this transaction.
