In normal waterfowl hunting conditions, say 35 yards max ange, do you think there is much of a difference in lead required when shooting a 1250 fps shell versus a 1500 fps shell, all other things being equal??

Basically does 250fps make that big of a deal in lead?
 
Let's assume constant speed

35 yards is 105 feet

At 1250 fps it takes .084 sec
At 1500 fps it take .07 seconds

Difference is .014 seconds

Google says ducks fly at 80 km/h which is 22.2 m/s so in .014 seconds the duck will travel .31 meters which is about a foot in difference of position.

Many other factors involved. Is the duck flying slower, your reaction time etc.....

So increase your lead by a c**t hair. Oh and the difference in trajectory will be about .96 mm so aim a weeeeeeee bit higher too.


So if you include all other parameters and considering your spread of shot the answer is No.

Oh and for all you Physic guys out there I know I assumed constant velocity which I know is wrong.

Another factor to consider is that the faster pellets have more wind resistance and will slow down faster than the slower pellets so that at some range they're speed will be the same. A target load of 7.5 shot at 1300 fps slows to the same speed as a load of 7.5 at 1150 fps around 40 yards. This means that the speed advantage disappears beyond the range that they become equal speed. Faster velocity also tends to open up patterns faster than slow velocity as well so target shooters know that for long shots, velocity isn't really your friend.
 
I personally found 1450 ish fps to be the sweet spot. The lead isn't that much different. If you have enough practice you will pick up on required lead on the fly. In other words, like posted above, it does matter but you will likely pick up on the difference and adjust if you have enough time behind the gun.

Lead? Waterfowl?

What am I missing here. Lead isn’t allowed.

I’m sure I’m just being “that” guy, but felt misinformation can be bad in a thread like this.

You are missing the fact that lead (pronounced leed) is being discussed, not lead (pronounced led).

Nothing like Kentucky windage to gain experience ;)

Sounds good, but we all know 1250 fps steel shot isn't effective out at 35yds.
 
I answered this question myself this year in Saskatchewan .Brought my SP 10 gauge custom 26 inch ported barrel yah yah but took old 2005 Drylock winchesters that I had gotten with the gun .They are 1250 and after three boxes I could not hit anything? There were some crushing long shots but they were the exception .Switched to my 12 g next day with the 1400 and no issue. I will say the 10 did not kick anymore than the 12 but lifting 10.5 lbs. out of a layout blind was definitely cumbersome.
