40 cal 1/2 wont slide in to gauge
Quote from Reloader on February 9, 2013, 10:10 pmAll of my other calibers work great on my new 550B, except 40. Strangest thing. About half of my production will not slide all the way in to my case gauge. I checked the brass and it's a hodgepodge as you can imagine. There isn't a particular manufacturer that is or is not working. I'm unable to pin point the issue.

Quote from Reloader on February 9, 2013, 11:35 pmcheck to see if your resize die is just a 1/16 turn from touching the shell plate when the platform is fully raised. Next verify that your projectiles (slugs/lead/fmj, etc) caliper within specs for the caliper that you're using. Then verify that your OAL is withing spec (i.e. you're not pressing too short of a round). Then make sure you're not crimping too much. Each caliber should have a certain type of crim (roll, etc.) that if it's crimped too much it can cause a bulge.
These are the main things that I've seen cause bulging that keeps a finished round from fitting a chamber gauge.

... that should be easier ?? Just think about the mechanics of the powder & case
belling station; then the mechanics of the bullet seating and 'taper-crimp' ! The belling & the taper crimp ?? Does the case length matter much for both of these processes?
(You mentioned 'multiple/mixed case manufacturers-- maybe ck different brands for OAL case length & then sort-adjust-load each manuf. brass all at same time. Also good idea proposed by Dillon to ck sized/deprimed cases in sizing gauge & if they fit OK, then try them in pistol chamber before reloading them & if both of these check out ok, then you know it's probably case length/adjustment related. However, if the cases are bulging at bottom-- & they were not 'fired' in your gun, then that could be caused by several issues-- your job is get your resizing die adjusted to remove the bulge- if possible; make sure shell plate is somewhat tight, but still turns to rotate between stations--then back all station dies out at least 1-2 full turns-- then lower handle to down position; next turn in the sizing/deprime die until it touches the surface of the shellplate & secure the lockring-- now using a 'bulging' case, raise handle,insert case & run thru sizing process-- then check
case in case gauge--if that works, then re-adjust your other station dies and reload !! If it doesn't work, then I would run the cases thru a single stage press and
see if I could get a better sizing job on them & then run thru 550B for reloading process-- otherwise probably toss them ? (ps- If your gun or your reloads are causing the case bulging after firing-- then I thinks you probably have other issues that need to be addressed) BOL, azgriz

Quote from Reloader on September 3, 2013, 7:47 pmMany .40 cal rounds are fogged off in unsupported chambers, such as Glocks, and mostly heavily loaded stuff 'will' bulge the case where the round was in the unsupported feed ramp area. Google '.40 kabooms' for further illumination on this subject.
Even were you to use some form of 'roll press' to iron out that bulge, I would be hesitant to reuse that brass in anything much more than light target stuff! Most of those "kabooms" occur when that weakened area is again subjected to the same "unsupported" location - and of course, once resized, you have no idea where that weak spot is.
