I have done several searches, but not found anything to clarify my question.
I know the guideline says,
"13.79: Sound moderators should be assigned a calibre, but it is good practice to permit them to be used with more than one calibre of firearm. It is a matter for the individual shooter, subject to the “good reason” test, to decide whether to use a moderator on more than one suitable firearm or to have individual moderators for each firearm".
If I have two rifles, say a 270, & a 308, and a variation for a moderator for the 308 only, is it legal to use that moderator on the 270, or do you still require a variation for a moderator on the 270 ?
I will ask my FEO to clarify, but I'm curious to hear other peoples interpretation !
