[QUOTE="SageRatShooter, post: 2125859, member: 100099"] Some of the guys have already covered this but my primer prep comes from my benchrest comp days. With either brand new unfired brass or once fired I first inside debur the flash hole with a piloted cutter (I have an old sinclair). You have to do this only the first time. Then I uniform the primer pocket using one of the tools already discussed. The primer pocket tool is also good for removing carbon on subsequent firings. I use it gently after every firing to clean the pocket. If you are tumbling make sure there isnt any media in the flash hole. I now do all my priming with a hand tool using only thumb pressure to feel the resistance. I have had primers "pop in" meaning there was resistance as the primer passed through the beginning of the pocket opening before seating. You also want to seat the primer slightly below the case head. I have heard that it should be a few thou below the head but I have never measured mine. As someone mentioned, if in doubt, put the primed brass on a flat surface and make sure they don't wobble on a slightly protruding primer. I don't know how much resistance you are feeling but this is an interference fit to keep the primer in the pocket against the force of firing. But to answer your question cleaning the pocket every firing is quite normal for comp or LR shooters who want that primer seated consistently and are looking for very low ES and group sizes and long distances.
