CorbinS. - what case is the .375 Express going to be on? Is it the 56 or 57 or maybe the 60mm?
: I built up a 9.5x68 on the 6.5x68 and 8x68 case, about 15 ago for a friend, and now see that Hornady and perhaps Ruger are bringing it out in a factory chambing. I do not think the action you have would take that big, .522" case.
