Hello all. I am about to bottle some beer and will carb via corn sugar. Can I fill up a growler while bottling this way? Will it hold pressure. Thoughts?
Any growler I've ever seen just has a cheezy screw on lid. Certainly not meant for pressure. If I fill a growler (from my kegs) it's flat within a couple days.
It won't hold the pressure associated with carbing. It takes a lot more than 2.3 vols of pressure to force 2.3 vols of CO2 into solution.
And it's not the cap we're worried about, it's the glass. The glass growler can explode and, if it does, it will propel glass with enough force to penetrate drywall and send you or the kids, or SWMBO or the dog to the emergency room or worse.

And there's another problem - how do you know if it's overprimed? They're not rated for pressure at all. 2 vols could be overprimed.
But, this is one of those things that's like driving without a seat belt, riding a motorcycle without a helmet, or not always pointing a firearm in a safe direction. There's lots of anecdotal stories from folks who do it "all the time" with no problems, but when something goes wrong, it is catastrophic.
