I have just got a roedale to replace my 308 cal mod that was on my old 243. and i am using it on the 6mm br, sounds about the same as my A-tec that is going but the weight saving is immense.
my roedale is a end of barrel mode and they will in general sound louder than a reflex type mod do to the different ways they are constructed,
im very happy with it, just need the a tex cmm 6 to go so i get my slot back,
bob.
