Not sure what bait you are referring to. Maybe in my electric valve thread? BTW, I did download your spreadsheet. I will use it further down the road once I get through the mechanical part here. So thanks👍This one here has my attention right now. I think with some tweaking it will be pretty neat. Different anyway. And I won’t have to cock it. I’m still trying to figure how I am going to connect barrel to action. However I do it, I want the chamber sitting directly in front of valve. So a break, slide or twist seem to be my options. I’m a single shot kinda guy, so no need for speed here. I think on my electric one, I’ll switch to a regular balanced valve next time I tinker with it. Dave
