I'm kinda jerking your chain! The Mauser M18 and Sauer 100 are made in the same Wunderbar Fabrique
They are basically the same rifle except that the synthetic stock on the Mauser appears to made by "Rubbermaid"
Oh wow, I missed the 2 replies above the Bergara question. I was eying a Sauer 100 in 7 Rem Mag. I see you were shooting factory ammo in that target, which is totally amazing.
I have heard the M18 and S100 were very similar, but thought there may have been some mechanical differences in the 2 other than the stock. I have heard a few gripes about the M18, but never a quibble about the Sauer. Maybe it was all just about the stock or that the stock sometimes makes a little difference in the overall accuracy. I am going on a foggy memory and 2nd hand info right now, though.
I first started drooling over the 101 and M12 iterations. Got hold of the 101 brand new, but handled as a display and the bolt was slightly tarnished. I got my gunsmith to Cerakote the bolt and the bottom metal plate the Titanium color, which made it look amazing. I got that rifle for $795 out the door on auction. Chambered in .300 Win Mag, it is one you have to hold on to when you touch it off. I believe it to be under 7 pounds, though I've never put it on scales. I keep hoping to find a 101 replacement stock in the beaitiful wood grain, but no such luck, I'm afraid. I have only toyed with it so far, but know that it shoots the 130gr Barnes TTSX and Hammer Hunter 124 grain bullets (very light for caliber, yes.). I made both somewhat reduced and full power loads, and it shoots all of them around 1/2 MOA. I have a wealth of 150 - 180gr bullets on hand to try, and want to get back on the range with it. That stock is very tacky and every piece of lint, fuzz, and dog hair sticks to it permanently. The coating will scratch off leaving a very plain piece of hard plastic underneath, but it needs to be removed from the action to properly do and refinish, and honestly, I haven't had the nerve to try to break it loose and risk messing up the way it's torqued into the aluminum block. Ugly and tacky I can work with. Inaccurate, I cannot. Stock aside, it is one of the great steals I've found all time. That was half price. The M12 is equally stunning, and these 2 may only be eclipsed by the Steyr CL-II. That's a slightly higher price point, however. That one is on the bucket list. I've owned a Steyr before, and it was a tack driver for sure, even if the stock was ugly. Lol!
Oh, and I think I should spend a bit of my wife's money very soon! My birthday is coming up and she works and can afford it!
