Thanks for sharing the info.

I actually just picked up some TG to try today as I've heard it's very stable in temp changes.

I loaded some at 4.0 & 4.1 with a 1.125 OAL and was going to chrony tomorrow.

Good data. Thanks for posting.

That's interesting, but 8 rounds, on one day, isn't quite enough to really know what the difference will be. Try two strings of 20rd from the freezer (let them sit in it for a couple of hours), and two strings of 20 at ambient and you might be surprised at how the results differ. The more I chrono, the more I realize it's really hard to do enough to be sure about things like this. R,

30 degrees F? Don't mean to drift the thread but my fridge is 33F and the freezer 0F.
