Congrats on the rifle, I think it looks great. Everything on it is what you wanted and I honestly wouldn't care about anybody else's opinion, it's your rifle.
In terms of accuracy, did you have the action trued and is it bedded? If the gun is properly constructed then I think it should shoot well and then it really comes down to load development, or your own ability.
I don't know your load development process but I think you aren't close to being done. I guess if you have gone through powder, primer, project and seating depth combinations then I would start pointing my fingers elsewhere.
Thanks for sharing.
