Actually, there is no such error in this version of the poll. I didn't list .41 Remington Magnum as an example, I listed ".410 Bore" aka .410 Shotshells which indeed use .41 caliber Slugs, and .410 Shotguns are typically smooth bore.

Furthermore, it's worth noting that bullet/bore diameter is measured differently in certain nations, ergo while .41 Magnum bore diameter is less than .41 in nations which measure bore diameter by the lands, it is otherwise in nations which measure based on the grooves. (And vice-versa when it comes to bullets)
Lastly, I listed both Bullet Diameter and Bore Diameter interchangeably in the OP for that very reason, to avoid arguments over diameter based on the differing methodology of determining bullet/bore diameter between nations.

If 0.019” doesn’t matter, then why the millions of words printed arguing that the 7mm is so much better that the .270?

No so much bullet diameter as case capacity?

Muzzle energy isn't a factor here, just the diameter lf the bullet/bore.

I attempted to illustrate this point by using typically non-magnum cartridges as examples after a similar poll on another forum received similar results, but it seems like I need to be more specific.

I know, I was just saying "in my head" (kinda wanna) not official.
Official - 40/10mm minimum - Happy now?

Preferred carry calibers for me: 357 Sig, 40S&W, 10mm, 45 acp - one of them is not official "big bore" I know. (But I give it a pass)

ETA: About the 380 .... I ain't betting my life on 380.

I'm of the same persuasion:
.410" for handguns
.416" for rifles

As you said, this is a handgun forum. The 7mm/.270 thing is regarding high-powered rifles and about as relevant to this discussion as a fresh gob of goose doo-doo on a pump handle.

The discussion is about bore size, not the energy behind the projectile. Those that argue lesser sized rounds like the .41 Mag are more POWERFUL than real big bore calibers like .44 Russian might as well be arguing about their favorite color. .357 Mag has more energy than .45 ACP or .44 Special, but .357 is SMALLER by bore size, just like .41 Mag.

OK, so let's compare my 50 caliber cork gun to my .41 magnum. With your "logic" the cork gun is superior.

Reading comprehension is important. Neither the opening post nor the post you quoted said anything about "superior." The question asked is very simple, and it is based on size, not power. The question was (and still is):

Quote:

I'm curious to see what is the minimum caliber/bore diameter the majority considers worthy of the "big bore" designation.

NOTE: This poll is in regards to Bullet Diameter, not muzzle energy. Please answer accordingly.

If you have no intention of answering the question -- why are you participating in the discussion? Do you understand that it's rude to hijack threads?

Suppose you asked whether people prefer nylon, kydex, or leather holsters. Somebody comes along and answers "PURPLE!". Is that helpful to you? Has it furthered the discussion? Does leave you feeling respected?

Think about it.

Thank you, Aguila Blanca.

@jimku
Neither the bullet nor the bore diameter of a .410 Shotgun are .45cal, unless you're thinking of a hybrid firearm which fires both .410 Bore Shotshells and .45 caliber bullets like the Taurus Judge or Smith & Wesson Governor, but those are chambered primarily for .45s with the .410 being a secondary option.

RickB · July 30, 2020, 08:20 PM

When the 10mm cartridge was being designed, they chose to go with large primers, so that it would be more likely to be grouped with the big bores.

kenny53 · July 30, 2020, 08:54 PM

I picked 44 as big bore but does it really matter? It's a simple poll, choose one, choose wisely.

That is exactly what I was thinking of.
I am leaving this thread, no further interest in it.

oprod · August 22, 2020, 07:26 PM

Before the 10mm came out I’d have said .41 mag and up.
The 10mm is on the line between mid size and magnum. So much so that imho the .40 cal would be considered mid sized, so probably 10mm would be as well.however a 40-65 rifle is considered big bore, so Mabel is all 40 calls. 38, 357, 9mm, 8mm, 7mm, all medium bore.
22, 25, 32 all small bore? 17,s and 20’s tiny bores??
Lol

40 for semi autos-the 10MM Auto, e,g., 41 for revolvers.

artoo · August 23, 2020, 02:34 AM

Been with the .40 caliber on up is big bore. Don't see a reason to change now.

Kevin Rohrer · August 25, 2020, 05:02 PM

Any caliber w/ a "4" or larger at the beginning is big-bore.

**Mike Irwin** · August 27, 2020, 06:26 AM

For me, it starts with my .41 Magnum and gets better from there.
