I got rid of the 6.5 before I got the can. have shot the K on my 300 win mag and my 7mm Backcountry. It’s not a very quiet can but it does cut enough sound to make it a good can for hunting and that’s what I was looking for. I will leave it on my 300 since it has a 26” barrel. I’m running the dreaded Scyth Ti on the backcountry. I have about 200 rounds of 300 win mag and 40 rounds of 7 backcountry through the Scythe. It’s still in one piece and if I trusted them more, I would keep the K for a 243 and get another Scythe for my backcountry. The K is ok, but if I was buying another suppressor, it would be the full size Zenith.
