Thread: barrel temp

I work on my hand theroy, I work with steel and pre heat temps everyday.

100degc for the average person not used to handeling hot stuff will be able to hold firmly a bit of steel for about 2 seconds.
150degc is a quick firm hold and release with the burn sensation setting in after release.
200degc is quick swipe smears fingerprints instantly and a hold of any sort is blisters guarenteed.
above that skin usually sticks to metal

I dont shoot much compared to most on here but work on my measure of 150c being max before a rest.

Internal temps will go way way way over this with rapid fire!

I tend to get the shell out & bolt open ASAP after the shot, then have a look where it went, write down the speed & pressure (if using the pressure gear).
I reckon that way the barrel gets the best possible chance of getting the heat out of it between shots.
I also make sure the rifle is in position & ready to fire before I chamber a round to ensure the bullet doesnt pick up heat out of the chamber & effect its performance.
After 5-8 rounds I give it a rest, shoot another one etc until it cools down.
I take the bolt out & turn it 90 degrees to the wind if possible, so the wind blows into the action & over the barrel, it seems to cool quicker that way.

I stand mine up as well (bolt out) - max 3 shots (thats all I care about)

Standing up creates a chimney effect
