Re: Match grade brass
not sure why you are saying/implying the "brass" is causing the ES of 30.
Is that the lowest you have been able to get it with a variety of loads/powders? If that is correct, then yes it might be the brass, but I doubt. Normally it is the load.
Are you using a bushing die for sizing the neck?
look at the ladder load development method on 12-24-02 in bullets, ballistics and try that. It will show sweet spots for your barrel with a given powder, bullet etc in 20 rds. then fine tune the load to that sweet spot.
Now if you cannot get the ES to 15 or less then switch powders. My first choice to try in 300 win would be H4831 and fed brass and 210, not 215 primers, 210 JLK or Berger for match loads and either the 200 or 220 SMK for non match. I know guys that have that combo and ES of under 7 and routine sub 5" groups at 1K
