A 6.05x500 somehow feels right to me. The volume increase is not that large. The cylinder is only 1mm wider on each side.

I´d use a 430mm barrel with that.

Also put a sorbo on the CH, which will reduce cylinder volume, and make your gun quieter.

I agree know that you wrote this. The cylinder volume will go back down to a standard vsr (probably) and it will be quieter. Therefore, the 430 will be the most efficient.
