Perfect gauge and love the classic gun our dads/grandpas shot. Shot some greenheads with my grandpa’s old Remington 11-48 last year just like he used to.
My dad has my grandpas Browning 16 gauge, probably from the 40s and I've always loved the way it looks and the age of it but never shot it. I have my grandpas Remington sportsman 58 20 gauge (not sure the year but they quit production in 65) but I don't wanna take it duck hunting because of the wood. I've used my brothers Remington 870 20 gauge since its synthetic but need to get my own.

There's less of a gauge/bore choice in the US. While all are still in production the 10's and 16's are really hard to find, especially the 10's, and 28's are relatively scarce too though not as bad. 410's have risen in popularity due to their use in handguns.
R32R38 you can buy 16 gauge at Walmart. Usually have Remington, Winchester, and federal options and the shot size I’ve seen is number 5s to number 8s. For 10 gauge I usually have to look at local gun stores that cater to waterfowl more.
All the Walmarts, Academys, and Local Gun Shops in my Area carry a variety of 16 gauge cartridges. Same thing can be said for the 28 gauge and 410. The only negative to them is that they will typically be more expensive than 12 or 20 gauge cartridges.
I think both sides are half right and the correct nomenclature would be "bore gauge", eg "12 bore gauge". Just like wire gauge or sheet metal gauge, it's bore gauge because you're gauging bores.
.410 bore is called ".410" because no one wants to call it 68 gauge. At one point in time, it was common to erroneously call .410 bore shotguns and the associated shells "36 gauge," and some European companies still mark them this way (Fiocchi does, for example). In reality, 36 gauge, if such a beast actually existed, would probably be somewhere in the .506" bore diameter area.
You may find the Winchester study on shot string length interesting and possibly factor this into your evaluation of the various gauges...Also you may want to study the research done by Jess Briley regarding the use of double jug chocking to achieve shorter shot strings which is what the Winchester study addressed...I digress now to relate why I only shot the 28 gauge for the 12/20/28 American Skeet events ands of course the .410 for .410 events...My last year of active American Skeet competition my 28 gauge average was extremely close to 100%...I was never able to carry a 100% average in the 12 and 20 events...I must admit I was shooting a Perazzi MT-6 with double jug choked Briley titanium tubes...Winchester claimed the two most balanced gauges were the 10 and 28...Jess Briley attempted and I feel accomplished improving the effectiveness of the 12, 20 and .410 with his unique chocking process...It's not all black and white, but this is it appeared to be from my experience...I shot many .410 100's and the Briley tubes turned the clays to dust in the .410 event...Many shooters commented how crushed my targets appeared to them...I do enjoy your channel and love the banter you have with your guests...Keep making great videos!
I HAVE A BURNING QUESTION ABOUT 28GA🧐 I have actually roughly conceptualized what appears to be a very efficient 28ga load (though it may require a particularly long shotcup) : if I could load 3" 28ga, I would place 2x copper spheres of #4 buck, #3 buck, 6mm, or 6.5mm varieties next to each other (horizontal to my eyesight) in the shotcup, then the same type of 2 spheres on top (but vertically to my eyesight) and repeat the horizontal-vertical pattern until I have filled the extra long shotcup up. 22 of these copper spheres should weigh about 7/8 oz, but the question I have about my load concept is simply this: could one actually fit that many in a 3" 28ga shell given the proper shotcup design and powder charge? And if not, then how many projectiles would fit efficiently and how much would they collectively weigh? 🤔🤔🤔 Also, how would it pattern compared to 20 and 12ga #4 buck loads? I also wonder how this load would work in various shell lengths ranging from 1¾" & 3½" and what the overall most efficient shell length would be. 😅🤣
You could have added a 9mm Flobert then there's the obscure 24, touched on, and 32 gauge/bore guns.theyre all pretty esoteric with the exception of 12,20 and .410 with 12 being the most common.
I agree to some extent about the gauges/bore. However technically here in america the bore diameter is what we call the caliber at least with rifles.. so a 12 gauge, for example, would be considered a .73 caliber.
"Bore" derives from Old German *borôn* (to puncture, plow, or drill a hole). "Gauge" derives from the Old French *gaugere* (to measure). Therefore, "bore" has more to do with the manufacture, while "gauge" has more to do with the measure. This entire discussion is about measurements. And so, my fellow Yanks have the right of it. 🇺🇸😁
So, it looks to me, (a tyro shotgunner), that for upland shooting a 20 bore with a three inch chamber would offer the same game range as the 12 bore . As i understand it, the longer shot column of 1 oz of lead could even be said to put the 20 bore slightly ahead of the 12 in that more pellets could be present at the same point of impact. Or, alternativly, i have completly misapplied todays lesson
Ten gauge FTW Pushes they way more bush when grouse hunting, and puts so much more in the air for flyers. With less recoil, at the expense of target acquisition. However, follow up shots are much easier.
3:28 36 gauge is based on 1/32 TROY pound, at .8229 of the avoirdupois pound & rounded off this is a .47 inch lead ball & the .47inch & 12mm base / chamber diameter .410 garden gun evolved in england from 1857 - 1892 & while it is NOT "directly" derived from any other cartridge its chamber is VERY SIMILAR to 1873 .44-40 Winchester based 44XL shot shells 1872 .45 colt 1873 .45-70 government "Forager" shot shell 1889 .303 British .410 is a 67.672 gauge & a four hundred & ten gauge = 22.49 caliber ;-)
No, 36 gauge has a bore of .506 inch If you converted .410 into gauge it would be a 67.62 gauge/bore. It simply isn't a part of the standard gauge/bore sizes.
No, 36 gauge has a bore of .506 inch If you converted .410 into gauge it would be a 67.62 gauge/bore. It simply isn't a part of the standard gauge/bore sizes.
Id generally consider a larger gauge an advantage as they make lower shot weight shells if you don't want the recoil of a full load 12 ga or 16 ga when doing something that doesn't need it like dove but it can still hold a full load power load if you do want it like for turkey or ducks. Something like a .410 bore or 28 gauge just isn't going to hold that kind of shot load.

Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Thus there are twelve 12-gauge balls per pound, etc. (That comes from wikipedia cause english isn't my first language) but the type of shot (buck, bird or slugs) doesn't have to do anything with the gauge. So no, a 1 gauge wouldn't be a slug.

The deference between bore and gauge is bore is for rifled rifles and gauge is for smooth bore guns( like shotguns)

Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Thus there are twelve 12-gauge balls per pound, etc. (That comes from wikipedia cause english isn't my first language) but the type of shot (buck, bird or slugs) doesn't have to do anything with the gauge. So no, a 1 gauge wouldn't be a slug.
