Very nice Vanders. Stocking looks good, well laid out.
I have always like a working open sighted Mauser in a Medium. Just something very cool about them
Your shootings results look good for a first bash, very good.

I agree with Daryl on technique. I rarely use a shooting bench in the proper/common thought of a shooting bench, as in a regulated range with the concrete bench at the prescibed 100yds/m. For all of my LR builds, they are all shot from prone off of there bi-pod and rear bag. GP rifles are tested some on the "bench" but all zeroing is off sticks. Mediums and heavies (I no longer can handle any heavies, but....)are zero-ed off of the high bench, standing as if off hand, but with forehand supported. No different than off-hand, nor if a hasty rest was taken in the field.
