Looks like ACPO may be heading towards trying to get .44 Russian off the obsolete calibre list - which would I guess make everyone with one suddenly need a section 7 or section 5 licence.
Don't believe this has ever been done before, so it may get dropped as not practical - but that didn't stop the same happening to Brococks and various starting pistols.
UK gun owners should write their Parlaimentarians, pointing this out, and pointing out that (I assume) there have been no crimes committed using .44 Russian caliber ammunition since the caliber was placed on the obsolete list.
