375 Ruger!!! I have thought about adding a Ruger m77 375 Left-handed African. I'm not a fan of 3 position wing safeties, but in that cartridge that would certainly not be a deal breaker. It would probably be the cartridge that would pull me into handloading.
375 guys. Anyone loading a 375 Winchester power level load for their 375 Ruger and/or 375 H&H???
The 35 Whelen is an easy fill. The CVA Scout would cover it! And for the cost of a case of shells. My LGS has one in the rack right now. I don't want to handle because it will probably come home with me. (I also think??? Would a 45-70 be a better choice

. ) I should ask my single shot friend
@Armored farmer which he would pick.
The 9.3×62 just has a certain mystery about it.
I really think the rebarrel or reaming would be the easiest way to go. I have always been a Model 700 fan, but a Winchester 70 or Ruger 77 would fit the build nicely.
@jmorris thanks for the 300wm comments. I have owned/used the 300wm and 300wsm in the past. But I have not tried the Winchester XPR. Do you have one? And how do you like it.
I think
@luv2safari makes a good point about the Mauser 98 and 9.3×62 just going together!

There are a few lefty Mauser 9.3 ×62 out there.
