Primer Pockets
Quote from Reloader on January 19, 2013, 5:14 pmHi,
When reloading 9mm on a Dillon 550B do you need to clean out the primer pocket after the spent primer has been punched out? I have always cleaned the primer pockets on my single stage?Owner of a 550B and loving it!

powder was used in loading ? You might check out the Lyman,RCBS OR Speer Reloading guides - just for reference. I guess it comes down to personal preference as far as I'm concerned-- but if they are 'dirty/gritty/carboned-up, then clean them with the primer pocket brush-- it will make seating the primer easier & less chance of a problem seating the primer. I think that it is more important that you make sure that the 'flash-hole' is not obstructed with corn cob or walnut shell polishing media.
(I don't know what Dillons answer is, but I have personally reloaded well over 30,000 rounds of 9mm on my 550B for target practice & very seldom have I had to clean the primer pocket. But if a primer is going hard or fitting too snug-- you need to check it & see why. CCI primers seem to fit more snug than Winchester) Any good and safe reloader knows NOT to force a primer & risk 'exploding" it in a press, so if you feel more comfortable, by all means, 'clean each pocket' ! and make sure you use a good taper-crimp on the bullet to get good and complete burn of the powder & seat the primer properly. ( I used a single-stage RCBS for almost 20 yrs (before I bought my Dillon 550B) & the primer feed alignment was not as precise & consistant as a properly adjusted Dillon press, so I think that makes a big difference.) I just clean/polish,then inspect & sort brass by manufacturer and reload-- (+ adjust taper-crimp if needed due to brass manufacturer or bullet type. Let's see what Dillon & others have to say...
