[QUOTE="Mikecr, post: 840418, member: 1521"] Let me try this one Larry. -If you adjust the body die down carefully to just sneak into your bump, you're doing as good as you can with that die(good results or bad). -If you go past this a schmidge, and depending on your shoulder angle & clearances, it's possible to lose that normal shoulder bump, as the shoulder-body area is taking energy to counter the bump. The body wants to squeeze the shoulder back forward. And if you pull a case and measure at that point, you might get the notion that your case needs FURTHER insertion to bump. -So, if you now adjust the die down further, you reach a point of re-forming the case body, and yes, your bump returns(but not with any precision/consistency). The side effect you might notice here, is excess sizing low on the case(cause you're trying to re-form the poor thing). Bumping can be tricky. Throw different lubes into it, and different presses, and precision in bumping can amount to local skill.. I have everything hammered out just right, for each chamber, and I keep every tool in a kit for each chamber. This includes separate dies, shell holders, any shims, gizzys, etc. I like custom dies and they're actually less expensive than the top factory dies. [/QUOTE]
