primers won't seat completely on lake city 7.62

[bhybl]

STOP !!! your primer pockets are already at SAAMI max depth as per my info above. Suggestion: seat a SPENT primer into one of your cases using your Rock Chucker priming attachment. Then use a small rod, maybe a nail cut flat on the end and gently try to tap the SPENT primer deeper into the pocket. If it (the primer) goes deeper you've identified your problem.( the priming arm) If it doesn't the problem would be caused by some part of your prep IE chamfering, swaging............ Or borrow a hand priming tool from a friend and see if the hand tool fully seats the primer.


I cleaned the priming arm on my rock chucker press, and still no luck. Then I grabbed my Sinclair hand priming tool and guess what? Every primer seats perfectly! I'm guessing the priming arm on the rock chucker is bent and the primer is entering the pocket sideways, thus creating my problem. Thanks for all your help!

if you have ever seated primers you know how it feels when they bottom out.

Now does your present priming system bottom out before you feel that primer seat? It should be very obvious. If so its the primer seater. If not you have very unusual primer pockets.

it has to be something stupid...probably not jumping right out at you, but when you find it it will be something stupid.

How 'bout that! It turns out msinc had the BEST answer. We went down a few rabbit holes but in the end all is good. ...... Now go out and shoot some bug holes
