.45 Bullet Seating

I am reloading 200 gr .45 Colt RNFP on a RL450. I'm having a problem with bullets not seating properly. If it were every bullet I would say that my seating die needs adjusted, but that's what I can't figure out. I have tried loading new, used, and trimmed cases, but still have some that don't seat in the groove correctly. Any ideas?

Thanks

Check your dies for lube building up inside. It is common for me to have to clean my dies of lube.

Hi Mark,

I checked them when this first happened and they were clean as it happened at the beginning of a batch. I only load .45 on this machine so it is always set-up. Again, it only happens once in awhile and doesn't seem to matter what condition the brass is in. Thanks for the reply.

I had this problem when loading 250 gr from Berry. I found it was the bullets. The diameter on some were off and they would seat too low. I have since gone to another maker for my 45 Colt and have not had the problem. If it's not every bullet then you might want to check another brand and see if you still have same problem. Mine went away.

Hi Phil,

I thought of that. I just tried a new box/brand of bullets and loaded 10 new Starlines. 3 out of the ten would not fully seat. I even turned the case to see if that made a difference and ran them up again, no luck.

Thanks for the suggestion.

RE: .45 Bullet Seating

• Are you using the correct seating anvil inside the die? Dillon dies come with 2 anvils: 1 for RN and 1 for SWC. Using the wrong anvil can account for some variation.

• Are you making sure to pull the op handle slowly and decisively over the full distance? You should feel the op handle bump at both ends of the throw.
