CH AutoChamp Mark III - Primer Question

[Browngirlsdad]

I have been loading 45ACP on an old CH AutoChamp for 4-5 years. I have switched out the powder system to use a Lee Auto Disc in station 2, and I have had good results. I have loaded several thousand rounds with this setup, but I have consistently fought the primer system. I tyically use WLPs, and they would hang up when the pickup slide was back and I would have to take it apart to free the wedged primer. I also had issues with Winchester primers not liking to seat in Winchester brass. It was almost as if the primers would hang up and deform a little and then not want to seat. On a whim I switched to CCI primers and this thing runs like a top now. Is there something with the WLPs that would cause this? Anyone else have this experience?

Welcome to THR!

Another C-H user here. I use 205 single stage along with 2 "H" type presses and 502 micrometer powder measure but use them mainly for load development as I have several progressive presses for higher volume production.

As to your priming problem, check to make sure they do not have crimped primer pockets. Picture below shows CBC/Winchester/Federal cases with varying amounts of crimp. If the primer pockets are crimped, the crimps will need to be removed or you will have difficulty seating primers.

I do not have problems seating Winchester LP primers (brass colored cups) in Winchester brass with uncrimped primer pockets.

Thanks for the reply and welcome! They definitely don't have the crimps. They are all winchester white box brass from the 100 round packs from Walmart. I can prime them off press on a single stage with almost no issues.
