Anybody have this problem before?





More Belling?

[NSB]

Your sizing die is on the tight side and your bullets are larger than what the case is sized to. It won't hurt a thing. Belling isn't the answer, that's only for the case mouth, not the case body. What's up with the Oal title. That's OverAllLength, which isn't part of this "problem". I've seen this lots of times and it doesn't hurt anything.

Size your boolits!

Wait... was the "junk" to the right stuck in your die? I have had wax build up in my die. Not that bad... But it would have if I had not caught it sooner. I am prety anal about checking as I go.

If you're talking about the "hour glass" shape, that's typical of Dillon's 45ACP sizing die. Replace it with a Lee sizing die to reduce the effect drastically.

Waxy lube buildup in a seating die is a normal reloading hazard. Need to clean out the
seating die periodically. This is super easy on Dillon brand dies, pull a clip and pop it
out, clean, drop in and reseat clip.

Or use a 45 LC die. No hour glass. A tip I picked up from the Bullseye forum.

take care

Yes, the title should have been over-all-length. The one on the left is the correct length. on the right is the way it ended up after about 150 rnds but I didn't notice it for about 200 more. The junk on the right is only part of what came out of the seating die (shaved lead).
Those are Lasercast at .452. I had to re-do most of them with a puller. It is a Dillon SD that i'm using.
There was quite a difference in length. It was set for 1.242 with a 230gr bullet. They were coming out about 1.200

You pretty much answered your own question. The lube/lead build up was ending up on the seating punch and as it built up your OAL got shorter.

You can have a little more belling too if you measure the case mouth OD after belling about .020 more will insure that the boolit actually goes into the case without shaving any lead or lube. It is virtually impossible to insure that every boolit starts perfectly strait and having the ID at the case mouth a few thou bigger than the boolit will help keep the angled starts to a minimum.

Then you close it down with the Taper Crimp die to .470 dia. for the correct amount of Taper Crimp.

As a production Machinist I didn't have to be told to check parts frequently for changes in the set up. YMMV.

But checking a round every 10,20 or 50 rounds is a good policy.

What people need to understand about progressive machines is that they will make scrap just as fast as they will make good rounds.

I would think that you had ample time to figure this out as you were pulling 350 boolits.

All knowledge costs something.

Yes! +1

I don't use the Dillon enough to get used to it.

This will happen less if you use a taper crimp die after you seat your bullet. Otherwise, the bullet is still going down as the crimp is being formed and a bit of lead is pinched off of a bullet and the lube turns it into something that won't fall out of the die and eventually changing your OAL not to mention possibly seating bullets crooked along the way. I too like the Dillon crimp die because of how easy it is to clean.
