RE: Rem 700 BDL goes back to Scheels
THe extractor has to pop over the rim of the cartridge otherwise the bolt will nto close. The extractor would keep the bolt far enough back that the lugs would not cam into their seats.
Many times the Remington extractors are very sharp and burred and will shave brass off of the rim when chambering. When you get brass inside the chamber area or where the lugs cam over then it can create problems like hard to chamber cartridges, bolts hard to close, & very hard to extract fired cartridges.
If this is happening it is as simple as creating a very slight radius on the extractor to remove burrs and the sharpness.
