Thread: Very hard extraction.

You mentioned in another thread that the handloads were loaded for another rifle, which I was taught was a no-no (unless they were very mild/starting loads). Add in that they are above max published load I would be very suspicious that they are too hot. You say no signs of pressure, but isn't sticky extraction a sign of pressure?
I would make up some rounds with starting loads and see if you have the same issue with them.
