7lbs for the WSM and 7lbs 8 oz for the 6.5 (long action), I like the 6.5x284 but the WSM is a 1/2 lighter.
Your scope choice is going to add over 2# with rings which is not something you really need for 500 yds and in, you might want to look at a NF 2x10x42 compact unless you absolutely need the xtra magnification!
