Re: Need some advise from you guys on a new build.
I think u've made a good choice. The 6.5-284 will be OK for elk and great for the smaller big game. I used 1 for several years and made 1 kill beyond 400 yds. using the 129 gr. SST bullet.
I'm always at odds with myself on which optic to get for these long-range SPs. I've always liked the 3-12x Burris for what it offers in it's size. But it is tuff to shoot from prone positions with a center grip stock off a bipod--something u may be doing a lot of if u're in shape and a walking/backpacking hunter. I have used it for tgts. beyond 1000 yds. tho. The secret to using this optic is to mount it as far forward as u can on a Ken Farrell base, and milling another slot thru the base for the rear ring. The Farrell allows for the furthest forward mounting base that i've seen so far. Mine's on a 7-270 WSM XP-100 that Kirby Allen built for me. This is the only pistol i use the 3-12x on now tho., as i have also switched to riflescopes on my other SP's, and if i can handle riflescopes on SP's, i'm sure u can too (I'm 5.5" tall and all of 130 lbs. wet).
