Primer pocket

[bohoki]

Don't clean pistol pockets, however I do clean the rifle ones. It does make a difference with rifle loads. IMHO

Here is a thread from a well-known high-power forum.

The flash hole is the hole in the head of the case that the sparks pass through to ignite the powder. In the manufacturing process this hole is not drilled, it is punched and that generally leaves a burr on the inside, or the whole "flap" of metal that was punched out. This can shield a portion of the powder from the sparks and lead to inconsistent ignition, case to case. A deburring tool does just that- cleans up the powder side of the flash hole for consistent ignition. This particular type tool has the depth preset so the cutter (a common center-drill) can only cut so deep into the flash hole:







All the mail order companies and most local shops carry these simple tools. A primer pocket uniformer can be used after each firing to clean the carbon out of the pocket. But you should at least revisit the primer pockets of your cases every three firings as the brass flows with each shot and they will eventually no longer be uniformed.

I clean the primer pocket of rifle cartridge cases everytime. For pistols, I don't unless I load for bullseye competitions.

from what ive observed it seems to be based mostly on superstition

alot like the barrel break in procedure that many swear by but is often has so many variations

i have the primer pocket cleaner so I usually always clean my reloads. The last batch I made I didn't though so to see if it makes a difference. If it does, I'll make let you know.
