First The .375 winchester requires a much stronger action. So if you use a regular model 94 action and put a .375 winchester barrel on it don't be surprised when parts come flying back in your face way to much pressure for the action.
Second as to the difference between the 30 and 38-55, 375 there is not the same bullet weight, even the fps isn't the same. Now as to killing power nope other than a bigger hole for the larger bullets which means more blood loss.
But if you are going to look at it that way then we only need one caliber either a 30-06 or 30-30 would be all you would need. The old 30-30 was used even on the big brown bears so I guess we could say all you need is the old 30-30 for everything.
But then look at all the other choices we would not need, nope no fun there need options in everything.

Besides I have two .375 winchesters and also a lot more levers in other calibers and even a few bolt actions and even some muzzle loaders.

In a free country the government doesn't fear its citizens and there firearms. In a crocked government everything is up to be removed even the citizens if they truly believe in freedom.
