JKob explained what the problem is. Listen to him. The extractor should hold the cartridge in the bolt but it should JUST do so. It should not be at all difficult to slide the shell up under the extractor but you should feel slight resistance. GD
This ^^^^^^^^^^^^^
But it's also very possible & likely that the chamber edge was not properly chamfered, especially if the breech was faced off to set headspace on a pre-chambered barrel.............a sharp edge will result & needs to be chamfered.
If not, it will scratch the case on both loading as well as extraction.
