How long for a purr?

[deerbasshunter3]

How long should each individual purr last? I feel like I am trying to make each purr last long, which I am not able to do, about 3 or more seconds.

Here is a couple good videos.  A turkeys purr does not carry on for a long amount of time.It Lasts about a second usually mixed in with some clucks and cutting.

Purrs are pretty fast, around a second i would say.  Scoot

Depends on what purr your making? 
Fighting purr 2-3 seconds, loud and course purr.
Content hen or feeding purr 1-2 seconds, slow soft and mellow purr.
Breeding purr 1 second, loud fast medium to high pitched purr.
Excited hen 1-2 seconds, soft fast high pitched purr.

That is good advice. Don't overlook fight purrs. They're money in the bank. Best content purr I've ever heard, and prob the easier one to sound real with is Schafers tear drop. Was there again last night, he had some left

about 1 second mix in some soft whines and clucks

fighting purrs are def a good back pocket call that can flip the switch in a hurry given the right situation..

They sound a lot longer than they really are. The length of an individual contented purr note, as in the first video BABS9 linked to, is about 1/5 of a second.

And this would be a good call to use when a gobbler is coming in to a feeding hen decoy?

What if I also have a jake decoy out?

Is there any particular cadence, or just a random mixture of purrs and clucks? I was trying to pick out a cadence in the first video but it seemed like as soon as I would, it would change.

For me on a Spring Gobbler that I am calling I purr very quick and soft (1 second 2 times .) most of the time followed by a soft cluck.  The purr I do is  what I call a double purr. This has worked for me on many gobblers.

You answered your own question, "it changed". Don't get hung up on making the same cadence over and over, birds change all the time, volume and speed makes more of a difference.
If your using a Jake with your hen decoy, and say your running some feeding purrs, if a long beard shows up and stands looking at your decoys. Give him a content purr, then switch to a couple breeding purrs and get louder. IF he starts toward you give him an excited purr, then a couple breeding purrs, then a single fighting purr. That should get him running to you! As a gobbler approaches a hen she gets more excited, your purr/calls need to do the same, sometimes a little louder and sometimes a bit softer, but they will quicken and get more excited!!!

Exactly a real hen doesn't have a "cadence". You don't want to do the same sequence of calls with the same number of yelps or clucks. You want to mix it up. Avoid repetition.
