A lot of the gas handling discussions tend to be focused around military rifles and older classic designs. Maybe as mentioned, since this was a bigger deal back then. The Tikka T3 is one exception, sometimes. I think this is due to the fact the T3 came with a plastic bolt shroud, and this drew peoples' attention and imaginations to this area. I don't usually see people discuss in-depth the gas handling of newer actions like A-Bolts or X-Bolts, Ruger Americans and all the similar budget rifles fat-bolt or not, etc. I do think manufacturers could often do more in this area, because... why not?
