    I have an older style Mec Resizer/ deprimer to go with my Mec 650. It is the one that comes down from the top and pushes the primer out while the resizing collet slides over the shell. I usually resize my hulls and then inventory them until I am ready to reload a bunch of them at one time. I noticed that the deprimer is actually mushrooming the base of the shell out, enough that they will not set flat on my bench, probaly 1/32 of an inch. The hole that primer is pushed out through on the resizer is 1/2" in diameter and the base of the shell is being pushed through that hole enough to mushroom it out. Apparently the pushrod had unscrewed itself a few turns over time. I screwed it back up and also squirted some WD40 into plunger as it appeared it was a little dry. This seems to have fixed most of the problem. My concern is now that I have gone back and looked at some of my resized hulls this may have been going on for a while as I have found quite a few with the mushroomed out bottoms. Will this create a problem for my guns, Remington 11-87 semis??? Thank you for any advice.

    I would say it will cause problems, I would inspect each hull you have deprimed and each you may have loaded.

    What are your opinions on using the resizer to begin with, my 650 has a deprimer but no resizer, when I deprime with it the bases on the hulls are fine.

    The shells won't cause a problem as long as the bolt on the 1187 closes OK. If you are shooting them one at a time in the same gun they were fired in there is no need to resize. If you are going to shoot doubles or skeet with them I would resize them. HMB

    ANy chance these shells could have created an intermittent cycling problem. After going back and looking at a lot of my shells I have found quite a few with mushroomed bases. My gun had started having unexplained cycling problems every now and then. I know cycling problems could start a whole new topic of discussion but being it is intermittent could the shells be causing the problem.

    Your old MEC resizer is a good tool and I am glad you got the problem fixed. I do not like the idea of the section of the brass containing the primer protruding beyond the base but if you test the shells and they shoot, everything should be fine. I like to have all of my hulls resized during the loading process. It is probably not necessary if they are shot in the same gun but I don't like the remote possibility that one could not chamber properly.

    As shown by my many posts on this topic, I years ago disconnected and removed the re-sizer collet from the 9000 MEC. IMHO the sliding collet is responsible for >90% of the MEC complaints. Cause: the steel collet fingers do not spring all the way back after repeated use. Sooner or latter a shell only drops partially down at station 1 and then the shell base is crushed when the lever is pulled. No collet, no shell base crush, no problem.

    I shoot thousands or relolads. STS or gun club. I have never had a failure to load in my KX5 or K80 after reloading with no collet for years.

    My shells are all fire formed.
