This is Big Bore?

[Dr45ACP]

One of the gun rags included 40 S&W in with "big bore" cartridges recently.

Is it just me or is that kind of a stretch? I have nothing really against this round, but wouldnt consider it "big bore".

Big bore generally represents most anything of .40 and above. I assume this is why its mentioned.

Would you consider...

... .404 Jeffries or .416 Rigby to be "Big Bore" rifle cartridges? (Heck, a "Big Bore" '94 is a .375 Win.)

I've always considered it thusly:

.40 and up= "big bore"
.30-39= "mid size"
.29 on down= "small bore"

I'm sure everyone has their own ideas. Heck, there's probably even some official definition...

I always thought of the .40 as a mid bore. Anything .429 and up as a big bore (just my opinion).

An article in American Rifleman a few months ago called the .40s & .41s mid-bores, IIRC.

It sort of depends on the perspective. When the army adopted the .45-70, it was often referred to as a "small bore" cartridge by soldiers who had begun their army career with the .58 rifle musket or even the earlier .69 caliber. The .69 caliber itself was considered "small bore" by British soldiers (including the Duke of Wellington) who considered the .75 caliber of the "Brown Bess" as the minimum necessary to inflict serious injury.

Yeah, its the "Littlest Big Bore."
There is going to be a Disney Movie about it next summer...

It came about when all the Big Bore guys looked at it and said "Isnt that CUTE?"
