Ok first thing I would get is the below product so you can get a correct measurement on how far you are bumping your shoulders. The hornady kit works pretty well so I will put a link below. The reason you want this is to tell whether you are bumping the shoulders back .002"-.003". If you are not bumping the shoulders then you will have a hard extraction after firing like you are experiencing.Full length sized

The .200 line is from the case head to .200" up the base of the case. I will put a link to give a little further explanation and where to measure. The reason this line is important is if your case is not sizing this portion of the brass you will get hard extraction like you are seeing. When you read about clickers in the PRC family this is the reason! If you have an undersized chamber or oversized die this will also cause hard extraction. Take a look at the link and those measurements so you can throw that variable out too.
