Re: Does a shorter barrel cool off faster?

I'm not buying that is the reason. I would bet it has more to do with US perceptions over European. We are much more likely to change things out "because" and not because of a quantifiable number like, the barrel needing changing.
My last barrel change I did at 12,000 rounds and according to GAP could have went farther, I really only changed it because. The rifle before that went to 15,000+ and we shoot the snot of out them, without any regards to time limits.
It's like bench resters who change their barrels whenever they get any spare change in their pocket.
I bet Europeaners are just not as cavalier about it. If you are saying 10 rounds and 1 minute per competition yard line are reducing your life by 1/2 -- those must be sandpaper bullets being shot here in the US. </div></div>
The saying, your mileage may vary, applies to this a bit. Depends on the application. Frank, Brux is pretty much on the money. Euros use same cartridge components we do, but in the Palma example, the factor is time. Time can work for you and against you when barrel erosion and barrel wear take hold. Full auto before plastic deformation actually does less goofy things to the throat than slow fire bolt. I've seen a bolt action 260 cooked out in less than 1000, in a weekend, due to the barrel temps, and the changes going on in that bore surface due to the conditions of fire and ambient temp..
