Tighten threads on takedown?

I am not familiar with that rifle, but assuming that you are talking about a threaded connection using peaked, not square, profile threads? So far as I know the correct fit is established when threads are cut - trying to make sloppy threads fit tightly is sort of "making do?" I had read that British Armourers would deliberately deform - with cold chisel - onto the tops of male peaked threads - this would make the threads "tight" as it was turned into the peaked female threads. Had also read that plain lead/tin solder was dribbled onto the male threads, so they fit "tighter" - but as said, all a bit of "make do", and not really as "strong" as correctly cut threads in the first place. If it is a shoulder that is being tightened up, was also a thing called a "breeching washer" - a thin washer that filled the gap between receiver and barrel shoulder - thickness cut as was needed.
Generally you can tighten take down joints by carefully working on the barrel thread. grind a chisel so it fits the thread then work your way around the barrel tapping forward, towards muzzle, go easy and keep trying. I have tightened many takedown shotguns this way. If you overdo it, some careful filing is in order.
Take downs will become looser the more they are taken down and assembled.
If you don't plan on taking it down and want it to feel tighter... use very little blue Loctite... 4 drops, each in the middle of the threads... at 12, 3, 6 and 9 put it together and leave it alone for a couple of hours... it should feel solid after that and if you do want to take it down, you still can... although on assembly you would have to repeat the blue Loctite.
