You might give a second thought to the Burris 8x32... it has a total of less than 39-ish moa of elevation... and the 30mm Signature rings have only 10moa inserts, so you could wind up loosing almost 25% of your elevation, and for long range, you will need all you can get.
Give some thought to the MK4-M1 scopes, either 10x or 16x, with 90moa and 140moa respectively.
At long range, the 1/8 moa adjustments are not as useful as they look in the catalogues, and they do eat up the markings on the rings.
Also, consider the Barrett adjustable rings. They have a continuous range of over 120 moa that's in the rings... I used a pair on a AR-50 BMG, with a B&L 10x Tac, and the scope's 100yd zero is 2-moa off the bottom, and 145 moa of "up" is available for long range.
As to the muzzle break... pretty is, as pretty does. It may look dog ugly in the gun store, but on the range, you will fall on your knees, and prase it... I have shot my AR-50BMG over 150 rounds, from prone, in one afternoon, and had no soreness... they work better than anything else on the market.
Spring has sprung, da' creek has riz, I wonder where dem kitties is? Here, kitty kitty kitty.
I have a Sako TRG 42 in .338 lapua. I have an 8-32X56 Nightfors NXS. I guarentee you won't be disappointed. You just can't beat the laser etched reticle and illumination system. It's tough and will live forever. I also have a 5.5-22X56 on my 22-250 Benchrest/Varmint rifle.
I suggest you contact Bill Shehane (champion benchrester and rifle builder) who sells them. Nightforce strictly regulates prices and they can not be sold below a certain price. Bill beats everyone's price by offering "free shipping" for the minimum price:
Go with the BR model NF (1/8 min) not the NXS (1/4 min). Keep an eye out on Benchrestcental.com and xtremeaccuracy.com. Both have classified sections also look at D&B supply (Bill Shehanes site) and he has swap and shop area on BR under cleaning supplies. I picked up NF 8-32 for $650 couple months ago. Saw 2 NF 8-32s listted recently. Also if you are Hunter Ed instructor, Leupold has big discount program under distributor for scopes for instructors. also just saw a 338 Yogi built on BAT action by Tooley on guntraders with NF scope price now was at $1600.
Also if you are within driving distance of western NC to to the 1000 yard nationals on labor day and shoot in any class. Last year when VA hosted match we gave 2-3 NFs away as door prizes along with thousands of $ of other prizes, powder, reamer certificates, stocks, other scopes etc. You will find used Heavy guns for sale, that are already built and all you have to do is rechamber. There is one now with custom 2" sleeved rem action, new 30" Spencer barrel, 1-10 twist with NF on it in 300 WSM for in mid $2000 now.
