First off, shoot the ammo you've already loaded--you may not need to change a thing. Given that it's a light load, the worst-case scenario is that you'd have to scrub some leading out of the bore.
If you don't get the results you want, then I'd get in touch with
https://fermincgarza.com/ He reamed the throats on a New Model Blackhawk 45 Colt for me, which is now one of the most accurate handguns that I've ever owned. I think he's 2 dogs on several forums.
His work is superb, and he won't charge you if you don't need to have anything done--just shipping to get the cylinder back to you.
