Thanks Mrspeedybob. Makes sense.
I was most curious about the actual cooling rate. I shoot a lot and have seen fatter barrels shoot well during sustained fire while thinner ones would shift point of impact and/or open up the groups significantly. Of course no two barrels are manufactured...
Hi Jeff
Once the outside temp of the smaller diameter barrel is the same as the larger diameter barrel, which will cool further, to ambient temperature faster?
The question is for otherwise identical barrels, just different outside diameters. Therefore same bore diameter, number and size...
Thanks Curl
During cooling, once the temp becomes equal in each, would the larger diameter barrel have a cooling rate advantage from that point on? Or would it still cool slower since it was holding more heat in its greater mass?
Conventional thought in the gun forums is that a rifle barrel that is smaller in diameter will cool faster than an otherwise identical gun barrel that is larger in diameter, after the same number of shots fired.
Is this true?
I have trouble understanding how it could be since the larger...
