Should be g2g, as long as the bore is not smaller.
There is no reason why you can not use your 30 cal can on a 223 caliber rifle, assuming the threads on each item is the same. Using a 30 cal on a 223 caliber will allow more gases to escape, which is the reason for the BLAST in the first place. You will also get MORE noise as a result, though, since the can will have larger porting and exit cap, allowing MORE gasses to escape instead of letting the can do its part to slow their escape.
