Home Forums Hunting & Shooting Express Rifles and Big Bores Only What would be the smallest big bore?

Winchester evidently considers their 375 Win lever action as “Big Bore”. They named it such. There’s a book on “Big Bore” cartridges, it covers 8mm and up. Al Miller wrote 358 with 250 grain bullets and up...

So as your post implies the title “Big Bore” is a definition that is somewhat different depending on one thing, “Opinion”.

To me consider a 416 Weatherby, well if that isn’t a big bore in cartridges available today, with the tremendous energy it produces, well???

Compare that 416 to a 50-110 or a 45-65 or a 54 muzzle-loader.

I’m not sure any of my rifles would be considered a big bore. But my 54 muzzle loader looks like it has a mighty big hole at the end of the barrel. My 416 loaded to almost 6,000 ft-lbs of energy feels like a big bore to my friends who have fired it.

Well we all have opinions and this post shows that clearly.

If pointed at me, I would say .177 or larger.

This is so SIMPLE...You know one when you see one!
If it goes...'Tonk! when you load it...that is also a clue.
If a stranger says something like "JEEZE, look'et 'That !" There is another clue.
