Sauer 150 - is not a gun as far as I know - just a user name taken from two of my favorite things.
In Norway one of the most popular types of competition shooting is a field marksman type where we shot at animal targets. Vitals equals 3 points - center X's equals 5 points. 30 shots total. Prone sitting and standing. All positions are non supported a.ka no slings, bipods etc. A clean round with 30x's = 150 points. Hence the 150
For a Sauer - well I have had quite a few 200's/202's and SSG 3000's, more than 15 since they first came on the market here in -89. I currently own 6 rifles with different barrels in calibers ranging from 6mm XC, 6,5x47 Lapua, 6,5x55, 6,5x284, 280 AI,308 , 30-06, 30-06 AI, 9,3x62 and a 300 Wby. All of the shot better than I'm capable of. Usually they shoot 5 shot groups without any special load development much less than 0,5 MOA right out of the box.
My Medium weight 280 AI (28"- 5/8" muzzle) is my MR hunting gun and shoots 150 Scirocco II's at 3100f/s in approx 3" at 400m. 162 A-Max shoots better - but I hunt for meat so fragile target bullets I leave up to you guys to use.
Most LR hunters here in Norway and Sweden uses a Sauer STR 200 (Skandinavian Target Rifle equals a SSG 3000 with a laminated 3 position stock) in either 6,5x55 or 6,5x284.
I remember telling D Tubb that he needed to get his hands on the distributor ship for these guns in the US since he would wipe the floor with the competition. This was before the 6,5 craze hit you guys- and we knew much sooner than you how much better a slick 6,5 bullet was under difficult conditions than a heavy 220 MK/300 Win was. Unfortunately I say he was already well on his way with his 2000 tube gun - which is probably better suited to you HP shooting than the SSG is. But still many of you should try this gun. You will be amazed what it is possible to get right out of the box for about 3 grand. Barrels replacement is done in a pinch - read 2 minutes and barrels on my side is around 500$ retail
