How many shots before the barrel is too hot?
So what is the general rule about how many sequential shots can be made from a big magnum long range rifle before the barrel gets hot enough to effect accuracy?
Matches are all timed and the barrel never cools down between shots.
The first shot in a hunting situation is almost always shot from a cold barrel. The second shot, if required, is almost immediately after the first.
Anyway, say that I am doing load development and shooting at the range.
How long do I need to wait between shots if I am using a 7mm SAUM/RUM?
Can I fire three in a row and then let it cool, or should I fire them one at a time with a couple of minutes between each shot?
