    I don't know enough about optics to know what to put on it.

    I know i'm aiming for an Atlas bipod

    For $1000 new I'd go with this

    http://swfa.com/Vortex-6-24x50-Viper-PST-30mm-Rifle-Scope-P44559.aspx

    Its a good FFP mil/mil optic, glass is nice and clear, tracks well and is very reliable. Tons of features for the $$$. Vortex have good CS too should you ever have any issues

    However if you're willing to look around its worth considering an SWFA SS 5-20x50mm. Its usually a $1500 scope but a few months ago there was a huge group buy over on snipershide where they were available for $1000. I bought one myself and gave it to my nephew, its hands down the best $1000 scope I've ever used. Because of the group buy you can pick them up NIB or LNIB for around $1000 over on the snipershide optics for sale section. In fact one just went today for $1050

    Heres some videos on it

    Whatever you go with, I'd advise you to go with an FFP mil/mil optic. Having and FFP optic allows you to maximize the usability of your reticle and going mil/mil makes the math involved in long range shooting MUCH simpler.

    I've posted this explanation of how much easier an FFP mil/mil optic makes things elsewhere, but its worth repeating here:

    Say you're shooting your rifle at a target at an unknown distance using an FFP mil/mil scope. You fire your first shot and you see through your reticle that your first shot was about 1.2 mils low and .5 mils left according to the markings on your reticle. Now because your turret matches your reticle, just dial in 12 clicks elevation and 5 windage (0.1 mils per click) and you're right on.

    If you know the size of your target, you can use your reticle to very quickly and accurately calculate the range of your target before you take a shot. Say you know your target is 36" tall. On your reticle you see that it takes up 2.5 mils. Knowing that 1 mil equals 1/1000th of the distance you're shooting, you can work out the range with simple calculations. Since 36" = 1 yard, and you know that at 1000 yards a 1 yard tall target will take up 1 mil, you can go ahead and divide 1000 by 2.5 which gives you 400 yards.

    If you're shooting at say 600 yards and you didn't see the impact but your buddy tells your shot was off by about 9 inches and you want to correct this. In your head you know that a mil is 1/1000th of 600 yards, or .6 of a yard. Knowing a yard is 36 inches, you work out that .6 of a yard is 21.6 inches (I do this by dividing 36 in half to get .5 of a mil or 18 inches, then adding on 3.6 inches for the extra .1 of a mil to make .6, but you can get here lots of ways). Dividing 21.6 by 10 gives you 2.16 inches, which is what each of your .1 mil clicks will equal at this distance. You proceed to dial in .4 mils to bring you to within .4 of an inch of the correction, which is well within the shooter and spotter margin of error.

    Have you got anything in mind for what loads you want to try?

    No problem :)

    Just some other optics options worth looking at

    http://swfa.com/Weaver-4-20x50-Tactical-30mm-Rifle-Scope-P40579.aspx

    http://swfa.com/Vortex-4-16x50-Viper-PST-30mm-Rifle-Scope-P44561.aspx

    I'm not sure what rings and base you got with the rifle, but a quality base and rings are vital.

    For .308 I tend to favor the 155gr Scenars and 175gr SMKs. The 168gr SMK is also very popular as it tends to be pretty forgiving, but I'm not a big fan of it because of its lack of performance when you push past 800 yards or so. Shooting at 750 or less it does great, but I prefer to have loads I can shoot at any range with the capability of a .308 rifle, from 100 yards to beyond 1000 yards. The 168gr Amax performs better than the 168gr SMK, but I just don't usually shoot it.

    For the 155gr Scenars you're looking to get 2850+ fps from them. Its a great bullet as it doesn't sacrifice the BC you get with the heavier bullets but you get extra velocity. 46gr Varget, Lapua brass loaded to 2.83" COAL has worked well for me

    For the 175gr SMK you're looking for 2600+ fps. One of my favorite loads is 44.5gr Varget, Lapua brass loaded to 2.820" COAL.

    RE15 is also a good powder choice if Varget doesn't work for you. Remember, don't take a slight increase in velocity if it means you're sacrificing accuracy or consistency. Experiment with different powder charges and COALs to fine tune exactly what works for you.

    If you're looking for some quality ammo to get you started before you start loading your own, Palmetto has a good price on 175gr SMK FGMM right now

    http://palmettostatearmory.com/index.php/ammunition/rifle-ammunition/308-7-62.html

    If you're looking to try some 155gr Scenars, Southwest ammo is fantastic. They also have 175gr SMK and 168gr Amax loads available

    Seekins are top notch and although I've never owned any of Ken Farrell's stuff myself they're good quality from what I've heard. I'm assuming its the 20 moa base?
