Pattern tighter/more open over time?

I honestly don't know the answer because once I find a choke/load combo that works I never go back and pattern it again. Same barrel, choke, load...will a gun typically pattern tighter, more open, or pretty much the same as more rounds are run through it?

None if you are keeping it clean. The more dirty it gets the more open and chances of POI start to change but it was take 1000s of rounds to make the combo start to really change due to just shooting it

10-4 REN. This is totally a TSS question as I have exactly zero experience with them + over the longer term. It shoots plenty tight now and don't need it anymore tight. Ran less than a dozen shells total. Both barrels combined. I'll plan on dove hunting just to get the action smoother to open..it almost takes a come along to open if now, especially after a fired round. Real tight metal tolerances I guess.
