I have the same model and agree about the eyebox but it has not seemed to be an issue in the field. I got mine as a demo unit from europtic. Saved a ton.

Let's see some 300 SAUM pics !!
Longtine,
What is your barrel length, and load if you don't mind sharing? Also assuming on a L/A with the .220 freebore you mentioned earlier?
What's your weight with the varmint contour???
Setup weighs 10.5lbs without the bi-pod.
Yes, it's the .220 FB. The barrel is a C6 CF barrel at 27". It's a tight chamber and cut to be .002" above new ADG brass. my CBTO is 2.360". I touch lands at 2.355". The bullet is in the lands at 0.005". New ADG Brass or resized brass with N570 67.8 grains gets me an average velocity of 2,968 fps average. I ran it up to 69.0 grains to 3,035 fps with pressure signs. The 67.8 grains gets me a vertical dispersion at 650 yards of 2" basically. But the 68.1 to 68.4 has the best disersion of half that, but it's very close to pressure and I'm shooting in Texas and the temps can kill ya. But that being said if I were only to use in the high country in the fall I would be at the 68.2 grains in the middle and I would shoot it all day long. At the 68.2 I was averaging 2,984 fps and an ES of 5. I confirmed it 4 times on 2 different days. It want's to be there. So that being said, I am going to cut a Brux Medium Palma at 26" and try to hit that node but I will be back at the 2,960 fps spot with the better dispersion.
To note: The only 7PRC barrel I cut was a 26" and I could not get to within 80 fps of what the SAUM pushed it.

As soon as I can find a Brux that same contour in 7mm that's what I'm building. I'm going to try a Medium Palma first but I need the extra length that you can get with the RV.
It works out good for me as I only live an hour from Brux's shop. I just ordered a 30 cal barrel around thanksgiving and they called and told me it was done right before Christmas. I picked it up on the 26th.
Aren't Palmas are usually longer than than RV?
They usually are but I ran across some in 27" and grabbed them. Hind sight I would have just waited on my orders to be filled. The RV has a little more stiffness to it also.
Thank you for the info Longtine. Great to know that the 7SAUM set up right will equal or beat the PRC!Yes, it's the .220 FB. The barrel is a C6 CF barrel at 27".
