Accuracy problem? Help please

[Medium rare]

I have been shooting ftr for a while now. I have a 308 with 31 5/8" krieger 5r barrel on rem 700 10 twist. I found a load that worked really well by accident while taking some wounded soldiers to a long range silhouette shoot at ridgeway pa. I have used the load since in a few matches and have been doing really well until the last match. I shot a 1000yd match in Houston at bayou and the first string I shot was a 147 6x then everything went down hill. To a 137 and 138. The problem is that it wasn't missed wind calls. They were hitting in random places unexplained. So I went home and thought it might be something loose so I checked the torque on everything. I went out to the range and accuracy is still not the same. I changed my cleaning process and I have the barrel very clean. That didn't fix it. I have been out shooting a few times with nothing fixing the problem. There are about 750 rounds down the barrel. Anyone have any ideas?

maybe scope went south. or carbon ring. or ur brass may need annealed. also if u suspect the throat area eroding u might set ur bullets a bit longer and see what happens. u really should have it scoped to look for any issues on the inside

I am going to have it scoped today. Thanks for the help. I anneal after every firing. The scope is the nightforce comp. I know that it is possible the scope went bad but I would think that nightforce would be a lot less likely. Hopefully it is just a carbon ring problem or cleaning issue.

It could be that your throat has moved forward by several thousandths and if you are not "chasing your lands" the bullet will be seated differently from where it did shoot good, and simply be out of tune. That is one possibility. As you stated the other possibility is a very dirty bore with hard carbon in it.

Medium rare, better get it fixed quick because the TSRA State Championship is next weekend! Let me know if I can help you in any way since you don't live far from me.

Thanks for the help. I scoped the bore today and there is not a cleaning issue. I am thinking I am just out of my node with throat or the barrel is breaking in more. I will add and sub a few tenths each direction and try seating depth this week and try n get it fixed before tsra next weekend.

You are right about tsra. I will be there ready or not. I think it will be a ton of fun. I hope to see you there.
