Recently had a hard to close bolt problem, and extraction problem... Thought it was because of my die set, but now thinking it could be extractor problem. When loading ammunition into the chamber it feels like the bolt gets stopped short. If I jam it, it will go in. But then I have to slap the bolt open to get it out(this is without firing). Today I noticed that the bottom of my brass is getting scraped up, which is what lead me to believe it was a extractor problem. Correct me if I'm wrong please or any input will be appreciated, Thanks
