10 gauge reload Issues

[Stan Hoover]

Hoping someone can tell me what I’m doing wrong here,

I’m reloading short 10’s on a Mec with the short kit and I started having some shells turn out like you see in the pictures. It started as a few here and there and I’m now at the point where 90% are coming out like this

These are fired RST Cheddite hulls, I thought maybe I’ve passed the lifespan of these shells, but it makes no difference if they’re fired once or 5 times. I’m starting to think there’s a problem with my final crimp station but I haven’t taken it apart yet. Has anyone had this problem?

your wad height is not high enough you will have to add abean or paper wads or some thing under the shot to bring up the height of the lead...there is nothing to stop your crimp from going down to far..adjustment of higher wad column will fix your problem...charlie

Yup more filler wad

With all respect, I don’t think that’s the issue.

I have some that are turning out perfectly, do you see how the shell appears to be squirting out the one side past the crimping stem?

I know when you do not have enough filler, it will close, but not tightly because the load is not up against the end of the crimp.

If you think your shot column height is correct I would try adjusting the cam and see if makes an improvement.

The RST hulls are not that great to reload but if that’s all you have….I place a 1/8” 20 gauge card wad in the bottom of the shot cup. A thin card wad in 12 or 16 gauge goes on top of the shot for the crimp. This is with 1 1/8” of shot.

I used to use an overshot card in the tops to keep my folded crimp flat in the 10 gauge . It works well but anymore the red beans are easier than a spacer wad and an overshot card .

Stan is the crimp die cracked?

I took a look at the die there Craig, it appears to be fine with out taking it apart,

I’ll have to look at the links provided by Pete and educate myself on the adjustment and disassembly of that piece.
Something must be going on inside that piece that’s allowing part of the shell to slip past what ever does the final crimp.

Reloading RST shells was just easy for me, I saved the hulls that I shot in the past and just started reloading, no trimming involved. I should probably be looking to upgrade.

I appreciate all the great suggestions, I’ll have to take things apart, see if I can come up with a conclusion.

After shooting the 10 gauge Hammer at the Fall Southern yesterday, it is a gauge that is just allot of fun, I enjoy the Big 10.

Suspicion here is the start crimp isn't getting a deep enough start and some of the hull is "outside" of the center flat of the final crimp and hooking the edge of the shell mouth. Has your adjustment on start crimp slipped or moved?
