Re: 338 thunder project

Ok, after a long wait, the thermal pics are here.

Ambient temperature is listed in one of the boxes and all temps are recorded along points of the barrel where the crosshairs are.

If you can't make out the numbers on the temp chart, say so and I will type them in.

Thermal 2:

Thermal 3:

Thermal 4:

Thermal 5:

So, from these pics, we can see that although I burn 20 grains more powder than the 300 win mag in pic #5 and I have already fired 5 more shots than the 300, my barrel never got hotter than 102 degrees farenheit and the 300 got up to over 150 degrees and stayed above 100 for 15 minutes!
The carbon barrel shot 8 aimed rounds as fast as I physically could and barely got above body temp. If you were to try this on a 70 degree day with a normal barreled 338 ultra mag, you would be able to cook a hot dog on the barrel!
Take a look at thermal image #4. It gives a readout on my neck as sp07 and shows it as 93 degrees. At sp06, my barrel is only 2 degrees hotter after 8 shots! That is amazing! Feel the back of your neck and that is roughly the temp of my barrel after 8 shots on a 74.1 degree day!

Proof the carbon wrap keeps things cooler to start and gets rid of accumulated heat 10 times faster than regular steel!

Can somebody please make a link of these pics to the thread I started called something like, "abs heat dissipation" in this subsection? THanks.

Re: 338 thunder project

That is very impressive - both the camera work and the carbon wrap transmitting heat so quickly.

I had to go back through nearly all of the pages to find the picture that showed where the carbon wrap started near the reciever.

I find it interesting that the inch or so of barrel steel near the reciever did not heat up but the brake did in the picture taken after 8 shots. I can't remember ever putting my hand in that exact spot to feel for barrel heat so I don't know/remember about it. But is interesting and probably has to do with the timing of taking the picture. After the last shot - might not have been enough time for heat to flow to there.

Very nice work and very interesting report.

Re: 338 thunder project

nice results GG. pretty impressive to say the least!!! I do have to say I am conscerned about pic #4 though. After carefully studying the pic it is clear that you are a redneck and you must immediatly move to OK with rest of us suffering in the 105deg heat.

Impressive GG, thanks for the info
