7mm Rem SAUM

Hi I would go with the 7mm Rem Saum because it is superior to the 308 buy a long margin but has the advantage of being available in an AR10 aswell as being able to rechamber their 308's with boltface mods or another bolt.
I would load them with H1000 and 175gr Sierra's.

The 338 Edge would also be great for long range but it realy is not needed and the cost of practice with a 338 will reduce the amount of ammo they will have to use.

The WSM will not fit in the AR10 so it is out in my opinion as the availibility of using diferent shooting platforms is a huge advantage.

Cheers Bill

Forget the 300 Win Mag

hi I would not even look at the 300 Win Mag at 1500yards the 300Win Mag with 190gr MatchKings at 2900fps is 7MOA lower than the 7mm with the 175gr MatchKings @ 2900fps. That's over 10'.

That is why the US feds use 7mm Rem Mags.

I would say the 338 Lapua for all the reasons already stated. Makes the most sense to me, if you want to go with a portable sniper rifle.

If you go back to why the 308 was chosen in the first place was because ammo was being carried by most of the soldiers at the start. Then when the 223 came along, there was not as many reasons to stick with the 308. I know there where still some MG's using 308. I am not so sure that if today I where in a sniper team that I wouldn't want the rest of the team carrying 223 because of the ease of carrying larger quantity of ammo. Point is, the reason for carrying 308 "ammo availability" doesn't hold water any longer.

I would think a 338 Lapua makes a bunch of sense.

And though it won't make weight, a suppressed (signature) semi auto 50BMG (like the new AI) would work very well in support of the 338.

I of course designed the 338 Edge in it's first form as a HTIR ( Hard Target Interdiction Rifle : Pronounced "Hitter" ). My initial version was built to be a rifle capable light hard target work (penetrating 1/4" mild steel @1000 yds was my standard) and anti-personel work out to 1760 yards. What eventually happened was it's success in the long range hunting world and the evolution into what is now the "standard 338 Edge hunting rifle". In this platform it weighs under 15 lbs field ready bipod included. The Edge holds one more round than a Lapua Mag and feeds much better than the LM. The LM version requires a "super mag " boltface upping the LM cost. So far as ammunition is concerned when I first built the first HTIR I contacted 2 different custom loaders and both assured me that since they already had military contracts loading the "Edge" would not be an issue as long as a certain minimum quanity was purchased. The 300 gr SMK load @ 2800 fps is a consistant load, brutaly accurate and performs all of the tasks I originally outlined for it. The big bonus is it is lighter than most current issue military 308 sniper rifles. The 18 lb 308 version fielded by a certain branch of the military is stupid. Knowing several of the end users and all agree that it was obviously not designed by the guys in the field nor was much input considered from them. Much like revamping the M40 series (on a long action ) to 300 Win Mag they could just as easly be revamped to 338 Edge. I believe that they just need new rifles designed for the job and not for the marksmanship units competition division. There are a couple of items I would do different to the standard hunting version to make it with stand the hardships of combat but only a couple. I would absolutely run a positive bolt stop, Sako or M16 extractor, fixed blade ejector to ditch the spring loaded plunger assy, and a robust detachable box mag assy. This is just my version based on long range shooting / hunting more than my Law Enforcement background. I believe that if you want a precision long range tactical rifle build one if you wabt a rifle to engage under 800 yards they have explored much better options than a 16+ lb 308 bolt rifle already. If it seems like I am opinionated on this I am, I am tired of our guys being saddeled with equipment that just is not up to the task. If they need 1500+ yard capability I say we do what we can to give it to them.
