So a rifle with .411” bore shoots cast bullets of .412” and .410 dia which weigh the same, have the same shape, and loaded the same will have the same velocity?

Done it...different velocities.

The easiest answer to this question would be to start chronographing shotguns with the same ammo and changing chokes.

I’m still betting there is negligible difference.

The question wasn’t how much of a difference is there. The question was IS there a difference in distance, there either is, or there isn’t. It is definitively yes or no. I’m betting there is a difference, albeit inconsequential. I’d also presume that difference increases as the barrel length decreases.

Yeah so on a treadmill the plane would still move forward. This thought scenario assume planes are like cars. It’s not true. Since there is no transmission, a plane on a treadmill would still move forward. If you tied the plane down there would be no lift because of no air speed.


But way to troll

Now what happens if the treadmill and the plane are going in the same direction, engine isn’t on, and brakes are free? Does it take off?

So who is going to shoot their shotgun over a chrono?

Again, you are mistaken, if all the pellets were the same material, then yes, but they are not, steel weighs over 10g/cc less than TSS, back to your feather analogy

Approximate weights of the shot material

TSS = 17.9-18.0 g/cc
Lead = 11.34 g/cc
Tungsten Matrix 10.8 g/cc
Bismuth = 9.75 g/cc
Steel = 7.86 g/cc

So the pellets vary in size just as bullets of the same caliber vary and carry corresponding energy and velocity per weight.

Choke has no bearing on the distance traveled, only the distance that there is a usable pattern with enough pattern density and energy to humanely accomplish your goal


Now if the question had been Which choke cause xxxxx shot to carry the needed energy, pattern density and velocity farther, then we can discuss chokes, bore size and muzzle velocity

Already do, has no bearing on the question asked

I also use this program to analyse patterns, have burned thru probably 10 boxes of their 80 pack large patterning targets

Target Telemetrics

Target Telemetrics

Before that I used this butcher paper, a Plexiglas target radius and a marks-a lot, probably 5-7 boxes worth

48" x 48" butcher paper

Before that I used these, I think there are still 3 cases of targets in the storage unit.

You would lose that bet

I load my own shotgun ammo and have done some work with a chrono. The work actually started by trying to settle on a clean burning load with low ES that was equivalent to a nitro 27 handicap practice load for clays that match the velocity I shoot for upland hunting. Shotgun powders are among the fastest burning on the burn rate chart and velocity is not linear with increased pressure like we expect loading metallic cartridges. Optimum pressure is around 10,500 psi. With 700x at 1240 FPS and hard magnum shot, with a rem STS 209 primer patterns beat a nitro 27 handicap load, and I get es in the high teens with claybuster figure 8 clone wad out of a Remington STS or Nitro 27 Hull. A very consistent load that outperforms good factory ammo. Initial loads are developed with a full choke to account for the higher pressure it produces, compared to an open choke. Velocity is marginally higher due to the increased friction associated with compressing the wad and shot charge in a tighter choke. Evidence of this is apparent by the increased plastic buildup in a tight choke compared to an open choke after a few thousand rounds. The forcing cone and especially in the choke are the only place I have plastic accumulation in the barrel. I have never tested how far they actually fly, nor do I intend to. Logic tells my increased pressure and small velocity gain out of a tighter choke would lead to some pellets that would be likely to fly a bit further. The tight choke compressing the shot also creates more deformed pellets that manifest as flyers than an open choke which are not likely to fly as far. Overall I would put my money on the pellets from a full choke flying a marginally longer distance if all else is equal. In terms of effectiveness I think the difference would be inconsequential.

Again it proves my point, question does not say different pellets but pellets.

I use whatever is in the gun

Regardless of what type of pellets, chokes do not make them travel farther, period

Choke design does not make them travel farther either

Break out the chrono then.

Already have, you would still lose, chokes do not make pellets travel farther

You don’t read very well, do you?

Just here fore the ...

I think the dog days are already here.

All my shotguns have modified cokes cause they have been scientifically proven to shoot faster, further, denser patterns, with all types of shot, and also group inside an inch with foster slugs

“cokes”? Unfortunately faster, further and denser is not always what’s needed.

Chokes do not change or establish distance..... a 1200fps pellet of #8 shot will travel roughly the same distance no matter what choke. Yes, choke could mean a very small difference but not enough to worry about.

Since everybody just wants to assume things, I came with data. This was fired by me, about an hour ago.

My conclusion: chokes don’t make a damn as to how far shot travels.
