Guys….
I’m not a newbie and I don’t plan to change the barrel on a rifle I just bought.
I bought this rifle three years ago, and so far, I have only changed the stock.

With my hand loads I’m getting an average of 0.59 MOA at 100 yards for 7 consecutive 5 shots groups, with a few groups under 0.5 MOA (below picture)
At this point I’m not sure if I’m limited by my skills or my gear. This is why I’m planning to swap the barrel in order to eliminate a variable in the equation.
