What is the diameter of a 28ga and 32ga Wad?

I checked 2 - 28 gau wads I have handy

Claybuster AA knock off is .510 at gas seal and .525 at base of shot cup

Balistic products HV28 is .550 at at gas seal and base of shot cup.

I don't have any 32 Ga wads to check

I understand that 32 ga. is the same as .410.

Claybuster WAA28 measured .505 at the gas seal.
Remington PT28 measured .531

Claybuster WAA41 measured .385
Remington SP410 measured .400

not true....not even close!!!

I bet if you emailed Balistic products they could tell you .

I may be wrong , but I thought I remembered 36 gau was either 410 or real close .

Johnch

No, not close. It's something like 67 1/2 gauge.

Fwiw, Dutch.

So if 28 gau is .550" a 32 gau should have a diam. of about .52 "

Johnch

A .410 is called a 36 ga by some manufacturers but it is not given the criteria for determing gauge.

Btw, how did you determine the .52" ?

BTW, I just cranked a few numbers and came up with the same thing, or damn close to it.

I agree....I just calculated the gauge of a 410 bore and got 67.567 Ga.

Or to put it another way if I had 67 1/2 equal lead balls whose total weight was one pound their diameter will be .410.....each ball weighing 0.014789618589834037 pounds and a 410 ball being .0316 cubic inches in volume.

If I had 12 equal lead balls which equaled one pound their diameter would be .729 (12 gA)

If I had 32 equal lead balls which weighed one pound they would be .526 diameter. (32 Gauge)

FWIW a cubic inch of lead weighs 0.4096847254801672 pounds and the formula for volume of a ball is 4/3 (Pi) r*r*r or stated it's four thirds Pie R cubed.

I used the same formula .
I looked it up in a OLD Lyman reloading manual .

I also did a reverse calulation .
I figured the ball weight , then calulated Di from that .

See Mom I did learn something in school

Thanks, everyone, for correcting my mistake about 32 ga. and .410.

All gauges other than the 410 equate to how many round lead balls would equal a pound, with the exception of the 410 which is the caliber...In round balls it would be a 64 gauge meaning 64 round balls of that guage would equal a poun

The 32 guage is a .52 diameter

he .410 Bore

By Chuck Hawks

The nominal bore of a .410 shotgun is.410 inch. Which is why it is properly called the .410 bore instead of the .410 gauge. In Europe it is sometimes called the 12mm, which is an inaccurate designation as a .410 bore has an actual diameter of approximately 10.4mm by metric measure. If the .410 had been named in the traditional fashion, by the number of lead balls .41 inch in diameter needed to make one pound, it would be about a 67-68 gauge. Many years ago it was also called the 36 gauge, and I have seen a picture of an old box of Remington shells marked "(36 GA.) .410-2 1/2 IN. (12 MM)." However, the "36 Gauge" designation was very inaccurate, as a true 36 gauge gun would actually have a .506 inch bore diameter.

raamw,
If you read what was posted above about the .410 and what YOU posted from Chuck Hawkes, you will see that the .410 as a gauge is 67 1/2 and not 64.

From early on I had only read it to be a 64 guage, I never heard it referred to as a 36 guage so I did a little research to see how it became labeled as such and found this article by Chuck, this was the first time I ever read it referred to something other than a 64 guage....your choice

If one does the math the old way the rounding could easily have caused that. Modern calculators and computers can do the math in nanoseconds and to twenty decimal places if wanted.

One would be remiss to say that someone was wrong to have calculated a 64 Gauge if he chose to work to a very few decimals.

It's all academic anyway.

Thanks people, was just thinking of making a snake load of birdshot for a 50 cal. Muzzleloader pistol. Guess I will try some 50 sabots for that. Would make a neat grouse blaster too.
