Leaving the ethics aside, I have an older Rainier 18" SS Ultramatch 223 with 7.5 twist and Rainier Match Chamber. I took it to the range today for the first time and using basic factory ammo (PMC 223A 55 Gr FMJBT) at 200 yards I got the below which I find quite promising to start with.
For the moment I am not ready to reload yet. With that in mind what would be the recommended bullet weight and if possible brand of factory ammo to run through this barrel to tighten the groups? For reference, I've made only 4 - 10 shot groups today and they all were in 1.4-2.1 MOA range the below being the best.
