I've heard of a few reviews but no 1st hand experience.
There was a guy shooting a supressed 243wssm and was having a few issues with it.... many videos on you tube.

The godfather of alternative rounds in AR's is Mike Milli aka Dtech of Dedicated Technology.
You can get a barrel, bolt and barrel extension from him. If you have him build you an upper her guarantees accuracy. 1/2" MOA is guaranteed most shoot 1/2 of that. He is using Shilen select match and match grade blanks. He stocks 1:9, 1:10 and 1:12 twist 20 cal blanks.

After purchasing and using his guns I would personally endorse his products:
