That would be me. I bought 10 of the Dumoulin actions 10-1-2014.
I turn Weaver S45 and S54 scope bases over and mill them flat.

In 2015 I put a #3 Shilen select match rachet 8" twist barrel on a reamed it to 6.5-06 A square.
I made a pillar for the rear and recoil block for the front.
I put a timney trigger and a Harris bipod and a rear bag on it.
I put a sightron SIII 3x10 scope on it.

I got Lee to make a custom mandrel reduction from a 270 Collet neck die for triple normal grinding price.
I got Forster to make a custom sizer die from a 25-06 sizer die for double the normal honing price.

120 Nos Bal Tips 3197 fps average chrono
0.92" 5 shots at 100 yards average

I helped separate cows from calves and the rancher let me hunt. I shot a whitetail doe at 629 yards.
I used a Mosin Nagant 300 Win mag I built that year to fill my other tags.

I build a number of rifles for myself each year, and do not think much of Dumoulins.
My scope base fix is ok. I have sent bases to other guys on other forums.
My problem is with the safeties.
If you have a Dumoulin Mauser action, you should have someone who knows what they are doing check the safety.
