talking about barrel temperature after firing a bunch of rounds. i have always heard and go by the "its ok if you can hold the barrel for 10 seconds" this is probably a good starting point but does anyone how hot is too hot?

Hate to give a wishy-washy "it depends" answer but...
I had one barrel,chambered .260 Rem) where the Point of Impact,POI) would definitely walk,spread out) with as little as a dozen rounds fired in short order.
On the other hand, my Pac-Nor 6BR recently got "quite hot" to the touch while sending a bunch of sighters down range very fast when my zero was way off after,stupidly) moving the scope back in the rings just before the match. With this "quite hot" tube, I then "went for record", shooting a 2.1" 5-shot group at 600 yards with about 1.5" of vertical.
In general, if the barrel gets more than warm to the touch I like to shut things down and let it cool.
Neconos.com sells temp strips you can attach to the barrel. These change colors at specific temps.
