I am in the begining stages of building my first custom rifle, Besides not being sure of the 257 cartrige to use, weatherby or STW. I am also looking for a glass stock, I have a browning 325 with that new dura touch rubber coated stock and I would love to get somthing like that. I contacted Mcmillian but they have nothing but Houge does but I will need to do some work to it to fit the montana action.. Anybody with any ideas? Maybe somebody that can do the coating .Thanks Bill
