I went from a 6.5# scoped 6.5CM to 8# (suppressed, scoped) 6CM. Already shooting much, much better with the smaller gun, but in equal weight setups I don’t think I’d be running to change the 6.5 unless you were ready to switch, kinda like others have said here. I do like shooting the 6CM a ton more, and due to that, get a lot more practice with it already.
