There’s that echo again, LOL!

KMW did bring up a good point of sticking with the 22-250. You said you wanted to use as much as you could. Keeping the factory barrel and going from there wouldn’t be a bad option. 22-250 will compete in 300yds with its eyes closed! And it can be competitive at 600. So I guess to think on. Good point out KMW.
