Small, Medium, and Big bore
I know this is a little antique but what was defined as what? My impressions from reading are:
Small bore: up to 30 cal
Medium Bore: This ones a little confusing I have read .366 to .375, but I would assume the 30's and .333 had to be here also.
Medium Heavy: Did this really exist, did the .375, .416, 404 drop into this?
Big Bore: I have conflicting stuff on this, a 470 NE seems to qualify, but another source said .5 or above.
I know the system is a little archiac, as modern powders and rounds have changed the whole equation. For example a 378 Weatherby or a 458 Weatherby have as much energy as any of the old classic's. I your replies don't get into what should be today. I want to know what was in 1895-1920. Maybe the whole mess was never clearly defined at all, any answers?

Well what would you call my 788 Remington .44 Mag , that is a big hole in the barrel, and a G-d awful small ejection port! BTW I am using .44 spl rounds in it both Hornady 180 XTP and 200 Win Silver tip, which chrongraph about 1050FPS out of it's 22" barrel . The 2.5X scope delivers them EXACTLY to the brain of goat ,sheep and deer everytime at less than 50yds VERY quietly, like a standard velocity .22-sort of. I consider this a big bore rifle! 8)

Was doing some research last night on this last night. Cartridges of the World listed the 425 Westley Richards as the upper end of the large-medium bore class. So with revision:
Small bore: under 30 cal.
Medium bore: .30 - .375 ??
Large-Medium Bore: .395 - .435
Large Bore: .440 up ????
I am sure it is not right still, still looking for input, but I think it closing, still troubled by the .5 or up on the big bore so maybe there is yet another class.
Gordon: Based on my very possibly incorrect chart above, I would say your 44 is in the LARGE BORE WHISPER CLASS.

Not that I would know, I just go by John Taylors original proclamations on African rifles.
Although he give a nod to a .577 and 600s as something "bigger".
Large bore-.45 and up
large mediums-below .45 to .40
medium-below .40 to .30
small- below 30
Not that it makes any sense today mind you.
Elmer Keith used a different explanation for North America.
Dangerious game- .400 and bigger
Brush and Timber- .405 to .270
Stalking- .33 down
heavy soft skinned
thick skinned dangerious
Bonnington copies a good write up with a modern version:
.375, the medium
and then 45s
anything bigger than 45
577s and 600s go into another class altogether.
He also copies the format of matching gun to animal which I like.
Feel free to make up your own definitions. They did
Not that it makes any sense either.
My personal definition today is this:
above .45 is a large big bore
.45 is a big bore
below .45 and above 375 is a medium big bore
.375 to 333 is a medium
.318 to .30 is a 30 caliber
below .30 to .243 is a decent gun
below .240 is a small bore for squirrels

To a squirrel, my .223 appears to be a big bore.
To a deer, my .308 appears to be a medium bore.
To an elephant, my .375 appears to be a small bore.
So, with this in mind, where does my .45-70 1895 Marlin rank, respective to an average-sized ardvark (assuming a potent Garret Penetrator is pointing in his/her direction)?
These caliber rankings are so confusing.
