I have an Axiom with the switch lug, I did it not for switching between caliber’s but when I shoot the barrel out. I can call Clayton and have a barrel spun up and when I need to switch it out I can in a couple of minutes.
I have a TT Diamond single stage that would fire when I closed the bolt, it was set at about 10oz when I got it. I run my triggers at 1 1/2 lbs after setting I have not had a single issue, and have 700 rounds through the rifle now.
