I dont know about the rest but the .338 mag is a bad bet. I got one new with a garuntee of sub -moa it would not come close. I call weahterby and was told that they would have to send a new rifle to me and they need the cal. of gun I wanted I pick the 300 wby mag great gun.. I ask why they wanted me to pick a diff. cal. and was told to surprise that the only 1 out of 10 .338 mags would hold the MOA.
