Hey bud..I have never shot one or tested one..but you may want to go look at a forum called ( silencer talk )...forgive me but I have yet to try the website links..a quick google on your part should suffice..
.best of luck..its just me but I always suggest this...unless you have acces the the state of the art stuff...you would probably be better to custom build one yourself and tailor it to your specific loads..specially since its a integral....but u have to do it legally..if not its a big big no no..but trust me..imho once you get one tailored to your rifle and preferred bullet..you will be much happier
