Choke break-in needed ?

[BowBendr]

Is see how a break-in period can work in a rifle barrel due to micro sized burrs in the rifling, but how does break-in affect a new choke ?
Most chokes are machined way smoother than a barrel, and I'm no metallurgist. I don't see how the low temps associated with shooting can "wake a choke up".
Bottom line, do we need to shoot a box or two of junk shells thru a choke before using turkey loads to check the pattern density ??

No.

IMO  New choke should undergo a very good cleaning, but that's about it.

Clean the chokes good.   Now with light lead loads I have seen it take 15 to 20 shells for a choke to settle in.  Now with the bigger loads like turkey loads I think you will see a little improvement but it will take but one or two to settle it down I think.

Good enough for me.
Thanks Gents !

Here's an article that I wrote many years ago but it's as meaningful today as it was then http://allaboutshooting.com/article_info.php?articles_id=475

That's been my experience with new barrels and choke tubes. Deep clean choke and barrel, run a box of shells through them first then start with the turkey loads. Deep clean at the end of the day the first few times out and then periodically. Great article!
