new to TAG but not new to airguns

Hello forum I’m cliff aka pindog2000 I’m new to this forum and was interested in owning a condor,talon.I’ve always visited this forum but never signed on but today I decided to be a member.I first started with airguns with a pistol a browning 800 mag for pest in my back yard and it grew to a ruger black hawk and then from there several rws springers this was in 2008.I’m a navy vet of 9 years 91-2000 so I’m not new to guns,over the years I sold all my springers and converted to what they called the dark side.I have then collected some decent big bores and small bores from a Haley qb .22 to a will piatt tuned Daq .50 bandit.The majority of my airguns are in fact qb conversions built by the late jack Haley ,but I’m thinking on a air force condor big bore.Xp air two year wait,extreme big bores nice guns but I want something a tad more tactical,Daq the airgun gods haven’t blessed me to get on his list so I think I will start here.I’m thinking on a .408 condor built for long range shooting may put up one of my guns to start the project where do I start ????
