IDK...this was a picture Eric sent me and was a 'prototype' to cut as much weight as possible. I have 2 barrels on order from him so will need to wait and see. For a hunting set up I'm not thinking about the barrel heating up.
For hunting I think a light barrel like that is great. Yes you're not going to need to do long strings of fire unless you need to spend more time on the practice range because those pesky animals keep getting away. The light hunting profile barrels from Desert Tech open up their groups after 6 to 10 rounds so it wouldn't be a surprise if that light profile did them.
