you guys can't be serious.
that maybe the case during winter, how often do you go to the range during the summer |
The difference between summer and winter here is 30 degrees at the most.
Seriously. it's a 5-shot bolt gun. Heat only really becomes a problem with barrel erosion or warping. How in the hell is he going to maintain that rate of fire? Do you know anyone that fires a bolt gun at a rate of over 60 rounds a minute? That's pretty much what it would take.
Lots of folks shoot bolt guns in highpower matches. No one sees a heat problem there. |
It's around 90 here in the summer, and about 30 in the winter....so that's way more than a 30 degree sweep. All I know is that after shooting 10 rounds through my .308 in about 5 min, the barrel was so hot that I could not hold my hand on it more than 2-3 seconds without it starting to hurt pretty bad. My 7mm RM was the same way...it heated up really fast. |
You should never fire more than 10 rounds if you want to hold your barrel for more than 2-3 seconds and not hurt your hand.
If you want to avoid hurting your rifle, you should never figure out away to make your bolt gun fully automatic and feed it with a belt.
Automatic weapons usually fire from the open bolt because an automatic weapon can get sufficiently hot to cook off a round if it were put in the hot chamber.
Your rifle has a heavy barrel, it will take slightly longer to get to temperature than a hunting rifle without heavy barrel. Once your rifle gets to temperature it will stay at temperature longer due to its substantially greater mass than a hunting barrel.
Touch is not a good indicator of temperature. If you are really concerned, get an infrared thermometer and check the temperature.
Metal objects transfer heat very well. If you left your rifle out in the hot sun, without firing it at all, the barrel would get hot enough that you couldn't touch it for more than 2-3 seconds. 140°F is hot enough that you can't hold a metal object at that temperature for more than 2-3 seconds without feeling pain.
The number of copper jacketed rounds fired is not a problem as far as heat is concerned. The rate that you fire them will determine the temperature that your barrel will reach.
Manufacturers of semi-automatic weapons will often give a sustained fire rate that you need to stay below to avoid problems.
I am not sure whether a bolt gun would have such a rating published by the manufacturer, but bolt guns are not typically fired very fast anyway.
You might get better answers from people by asking how many rounds per hour do they fire through their bolt guns.
