    If they produce that kind of velocity, what kind of chamber pressures do they generate? Scary high, I'm assuming...

    Cut that Longshot back to 33 Grains with an 1 1/4 oz load and you will break any bird they throw. Drops crows at 70 yds. loaded with 6's if you can lead them right.. If I remember right that's about a 1450 fps load in a gun club case with an old Uniwad.

    Big Jack I do not load 1 1/4 oz, when 1 1/8th 6s does very well

    0 or 36" instrumentation. Big difference.

    What is the difference?

    The difference is in the placement of the chronograph. In the US typically 36" from the muzzle to the first screen. In Europe many manufacturers place the chronograph at the muzzle. That first 36" of travel can see a couple hundred fps difference.

    Do you use one of them, jbailey? The promotional literature says they don't work with shot, doesn't it?

    jlmccuan, in US labs, it's the midpoint of the inductive screens that is at 3 feet, not the first screen. And I have often wondered about the massive slow-down in the first two feet. Why such a big change there and not later? Yes, I know that's what DZ always wrote, but I think he might just have misinterpreted what EL wrote in is American Rifleman article in 1988 or 1989. I think DZ said the shot was hitting the air and slowing down, but that never made any sense to me, since the shot surely pushes air in front of it and so the charge is not hitting a "wall" of sill air at the start, but later on, the shot surely is and it doesn't slow down anything like that.

    I used a chrono at muzzle on a 325 WSM with custom 150 gr load and the chrono is no more. The muzzle blast pressure was more than the unit could handle.

    Neil, As a (or the) resident researcher/scientist I'm sure you know the answer to this question can (and probably has) certainly be tracked (even if not the cause).
    I don't portend to know the answer but I am willing to opine that, as with many things, the top of the curve drops much more swiftly than the middle of the curve. (Often times in curves, the bottom also drops faster than the middle. Probably not in velocity/time curves. Though, most certainly in velocity/distance curves)
    We are talking here about, for all practical purposes, is the max velocity attainable for a shot shell. It seems logical to me that the drop from that marginal maximum velocity is sharper at the start of the event than more into the middle of it.
    But again, I am not a scientist. Just an interested spectator.
    Regards, Jake

    Sharper speed reduction, sure, Jake. But what we are talking about is a drop of 200 fps in the first 3 feet and the next 200 fps in what, 20 yards? Why the big difference? Particularly since there must be a "wind" of the air which was in the barrel and must have been pushed out by the shot & wad so will have some velocity and, hence, produce lower air resistance than the rest of the atmosphere the shot goes through thereafter.

    I admit that I didn't understand a lot of the article Mr. Lowry wrote and it does have the reading of the inductive chronograph being lower than the shot, or some of the shot, I don't really remember. I'll try to find it and PM it to you.

    That higher speed does show up in Lowry's Shotgun Ballistics for Windows as the muzzle velocity. I'll have to look that over too.

    What I am pretty sure of is that Lowry never cited "hitting the air at the muzzle" that DZ attributed the difference to. I think DZ was just trying to make sense of what he had read too, but he did present it as a fact, not his own interpretation. And there's another thing I've never worked out. When you make all the adjustments for the effects of choke, the speeds reported for the same shells by inductive and light-operated chronographs differ by only 25 or 30 feet per second, maybe less. The light-operated on is maybe five feet from the muzzle, so I'd take 50 fps difference. But not 200 fps.

    It's important to remember that the inductive and the other chronographs are tracking different things, namely, the center of the shot-mass for the first, some leading pellets for the second. That's proven by the fact that tightening the choke speeds the reading up for the light-operated one, slows the reading down for the lab speed-reader.

    I'll get reading and see if I can understand this, but I never have, not really. And I've read it over and over again.

    would think you would tend to shoot the wad through the pattern disbursing it.

    You could shoot behind the bird and still break it with that speed.
