Hello i go by Lineworker81. I just got my first stw lastweek and i have some questions. I got a 7mm stw sendero that looks to be shot very little and i think was made in 1997. Today i looked at another one and the caliber read like this 7mm-stw and it appears to be a later model. Is there any difference in the twist rates? ive saw it mentioned on here i think. I just want to learn all i can about these two guns since ive searched for 3 years to find one and find two in a month. Are they rare or just hard to find? Im curious if Remington made alot of them or maybe they are held onto and seldom let go of? O and mine reads 7mm stw no - which i kno is just a minor detail.
