I've been designing wildcats and reamers since 1982, read Precision Shooting mag while in print and a lot more on 6mmBR.com than barfcom. Everyone has an opinion but there are no benchrest barrels made with a compound throat. As long as my old school chambers with normal freebore will shoot Hornady 123gr Amax factory into 1/2 MOA and chamber I think I'll stick with the benchrest thought on chamber designs.
Woohoo, you have made the most concise summary of the controversy surrounding the Grendel chamber!
It is what it is, the accuracy is superb for most purposes, including some very competitive long range shooting. But, to my knowledge, the cartridge was not designed as a serious bench rest item.
The Grendel reloading handbook makes no pretense about what constitutes bench rest chamber design. It does, however, discuss why the Grendel chamber is as it is. Your comments above suggest that it is possible you have not looked at the relevant chapter.
I also searched for the term "bench rest" in the more than 7,000 threads in this forum. Guess what? I couldn't find a thread that talks about bench rest shooting as a competitive sport. The Grendel is not a bench rest cartridge, nor was it designed as one. It does, however, regularly show better than the 1/2 MOA you indicated when used by good shooters.
You will also see a number of posts in this and other threads that recognize the fact that design features that make a cartridge a top bench rest cartridge also tend to cause reliable function problems in the AR15. And yes, I suspect that there are very few AR15 rifles in the top levels of the bench rest world. There is a reason for that.
