Dad just bought a factory pre 64 7MM STW 26 in barrel lazer ported, I don't know why any one would port a stw. I load for two other STW's now, mine and my brothers, this Winchester is kicking my butt, I have four loads that the two Remingtons will make one hole groups with. can any one tell me what the major differences are between the two are? found out that one being mag box is shorter in the model 70 compared to the 700's Did Winchester free bore there barrels? currently using all Nosler bullets and Hodgdons 4831 which both the Remingtons shoot very well.
