Nice job! If you have not already, I would test it with multiple ammo varieties to check for reliability across different ammo loads. If it eats it all, you have finished the job. If you start having problems with weaker or hotter loads, then implement 98's suggestions above.
There's nothing wrong with a rifle that functions exceptionally with a specific round until you can't get that round. I, and most others on the forum, prefer to have a rifle that may prefer a certain round but will function well with anything available.
