With this caliber you should be able to get 2 or 3 shots off before the barrel needs time
to cool. check it with the back of your hand if it feels uncomfortable stop and let it cool
down 5 to 10 min.
If you have a sporter weight barrel this will be about right ,With a heavy barrel 4 or 5
should be no problem.
And as stated if you shoot the big cartriges ( 100+ grains of powder) they will heat up
much faster. I had a 30/378 with a #3 contour barrel and after only one shot of 122grs
of powder you could feel the heat and after 2 or 3 shots I needed to wait
Some match rifles must shoot 10 to 20 rounds in quick order but they are normally heavy
barrels and even though they get hot the heavy barrel absorbs and distributes the heat
I have one of the infrared temp readers for checking exhaust temps on race cars and it works
well for barrel temps and is easy to check any location on the barrel.
But if you use the back of your hand you will never over heat a barrel.
