Well... here you go. Same model as @F Class John but coupled with my possum hallow bore guide. 85 degeees today. Its working great. The cooler is coupled to the bore guide with a silicone adapter that came with the cooler.

This is a michigan DNR range. The baffles I think are to minimize the noise for nearby neighbors 1/2 mile away. As far as the shooter is concerned I really don't see any difference in noise. I honestly don't know what the benefit of the baffles are.

However, I do get 12 feet wind free! And no rain on my head.

Our 1000yd range is on an elevated concrete platform to shoot above crops (like maize). Each mound position has its own noise attenuation box to shoot through, about 5 foot long and fully lined with thick sound-absorbing material. It certainly makes for less noise near the firing position but it actually makes zero difference down near the targets. We tried shots inside and outside the boxes and there was no difference at all down at the targets. This was not just judging by our ears- I was using a top-end datalogging impulse SLM. Clearly the noise at the targets is highly dominated by the supersonic crack of the bullet.

From the nightmares of Fujinator Industries......I took a CO2 power
inflater and thinned out a valve stem to fit a particular chamber.
Compressed CO2 is cold. One cartridge discharged slowing will get
you back in the game. I advise a patch out after spraying......Never let a
bad Idea go to waste, and no extra baggage......I do use an air mattress
pump when not pressed for time when doing load work ups. I also have
a laser temp gun to check barrel. You can get one cheap at "Horror Fright".
