O-Rings on my LAM plunger are shot, getting as much splooging above the plunger and into the bullet grooves. Not finding much by way of replacement parts for the LAM. Need either the o-rings or a new plunger. Suggestions?

(Also, dumb question - but I ran several bullets through and couldn't figure out why they weren't looking well-lubed as they always do. Now I know. Once I get the part(s) replaced, can I just run these again, or should I remove the lube and start over?)

Call RCBS they may be covered by warranty.

I agree. Call RCBS. They have been great when I had issues. Ask them the dimensions of the o ring and then next time you can go to the local hardware store and pick them up.

I have two LAM’s, but haven’t replaced an o ring in years.

Thanks guys. Don't know why I thought these were a purpose-built RCBS thing. Short search here gave me the size as 1 1/16 OD x 13/16 ID x 1/8" thick. Just ordered a bag from Home Depot.

Thanks again.
