Re: Barrel Cooling
In 1000 yhard competitions where 10 shots are fired for record and 5 to 10 sighter shots were fired first, the barrels do get extremely hot. This is especially true in the 90 degree heat and dosen't matter if the shots are fired fast or slow. The barrel still heats up till it will burn the hand if you hold the barrel for any length of time.
Just to give you an idea of how long a good barrel will last even when it is heated to extreme, the Hooovers, who are great shooters, shoot their barrels until they have 2000 rounds on them and then they rebarrel at that point. They have found that, at that point, it is usually at the end of "two seasons" or years of competitions for each rifle. John has stated they (the barrels) are still shooting fine even at that point. They just don't want a berrel to go south in the middle of a season.
If you shoot more at one setting and in the time frame of 10 minutes then the above mentioned amount of shoots, the over heat will no doubt effect accuracy but, 15 to 20 shots does not seem to do this, at least not from what I have seen.
If you have a pencil thin barrel the info above does "not" apply.
