Has anyone actually built a .375 Ruger on a Mauser action? If so, what exactly did you (or your Gunmaker)do to it to make it function properly?

The answer is yes. Open the bolt face to .532".

Yes
in the process of getting built, 375 AND 416 Ruger on Satterlee action, wider box but not sure what else stuart is doing

Mine is built on an FN action originally built in 270. Besides the bolt face needing opening, the rails also need to be opened up for the fatter cartridge.

mine is on a BRNO action. had to open the bolt face and widen the rails. didnt have to do anything to the mag or ramp.

Mine is on an Belgian made FN98 action, magazine holds 2 and one in the chamber, cycles just fine and shoots like a dream!!

while it wasn't totally necessary, I fund that shortening the case about 1/16th inch allowed me to crimp into the cannelures I had at the time....no big deal at all.

Just a point of information and shameless promotion! We at Sound Metal products have started a run of our pot belly for the 375/ 416 Ruger. Can't remember the mock up exactly, but do recall it holds at least four down

I personally think these cartidges are really going to take off, you just have to get uesd to the lettering on a fine custom rifle when it says "375 Ruger" "416 Ruger"
