I' ve had my SA M1A for a few years now, and put about 500-600 rounds through a new krieger heavy. It has feeding problems at rapid fire:

-The rounds will not seat in the bolt properly, the rim of the shell is not being "grabbed" by the bolt.
This happens during rapid fire. Do I need a new bolt or extractor?

Break down the bolt and clean thoroughly. Consider a USGI extractor.

Could also be a mag problem if you aren't using USGI mags.

E mail sent. Do you mean the bolt does not close all the way into battery, but the round was stripped and pushed into the chamber?

If the bolt isn't closing all the way........that sounds like a binding or possibly weak op rod spring.

Do you have extraction problems?

ETA: You will probably not need a new bolt. Like was said earlier, replace the extractor if needed with USGI, and you should be good to go.
