Joined: 19 Jun 2015 Posts: 19

Getting way too much free-hull to make a good crimp. Dished is an understatement... I'll check my bar to ensure its throwing 1oz of shot, maybe its short throwing.... I bought some nitro cards from bpi, but they don't really readily fit in the shot cup, so I guess I need different filler wads.

My powder is 21gr of universal.

I'm pretty new to shot shell reloading, so I apologize if its a silly question.

Anyone use this combination of components without this issue? There are loads I see with with combo, but I just fail to see how they would work.

I believe the z16 is for hevier loads 1 1/8 and even 1 1/4 without the use of fillers. So if your not using a filler wad I would think that must to be your issue.

Yes check your shot drop weight and powder weight first , charge bars and bushings usually throw light . Seems like that load should fit .

After looking at it you may need a filler with that wad , if so 28ga card wads will fit in the shot cup under the shot . You should have about 5/16th " from the top of the shot to the end of the hull , no more than 3/8" to get a good crimp .

The SG16 wad would be a better choice no filler needed.

The 1 oz. Z16 load fits perfectly in a 2 1/2" Cheddite hull, so a 2 3/4" Cheddite hull will need something to take up the empty volume. You may want to try the OB16 1/4" spacer from BPI. Or you could get Byrdog's trimmer and cut your hulls down to 2 1/2".

Is too much wad seating preasure a culpret? Putting a cherio or 2 in before before dropping the shot might help.

Or you could just drop a thin 28-gauge overshot card on top of the shot at the pre-crimp station.

I use the same Universal, 1 ounce load as you, only with the SG-16 16 wad. I get great crimps with no fillers, cards or anything.

The 21 grains Universal load in that Cheddite hull is listed as a1200 fps load, but running them across my Oehler chronograph I only got 1170 fps. I had to go up to 22 grains to get 1200 fps.

Roger. I'm going to order some sg16 wads... I also just picked up 500 rounds of fiocchi and Winchester...

how does one tell what hull the Winchester super x dove loads use? They are probably early 90s vintage or so?

I had the same problems with Federal hulls. I had used a spreader in a box of Herter's hulls so it was not that much of a problem on the crimp. I just ordered the 28 ga, fiber wads to use with the BP 1oz wads I have.

One or two Cheerios under or over the shot , done!
I prefer under.

BUT get the correct wad and no issues with fillers,

Sometimes I use cheerios, but they crush down too easily if there is much space to be taken up, like in this case.

There are however a zillion things you can stuff in there-- it needs to be light so it doesn't add to the payload charge, firm enough to resist the crimp and provide a good crimp, and flimsy enough to not impede the shot patterns. It also should not be hygroscopic (attract and hold water) like flour (or cheerios heh) if you're not shooting it quickly.

Go to Harbor Freight and buy a set of hole punche chisels for $10, the large one will punch out nice size for 12, 16, 20ga wad fillers. Here's the things I use:
felt, 1/8" thick, buy at Michaels or Hobby store
foam meat trays, the stuff chicken is packed on.
cardboard
flax-seed <<< I like this best! 1/2 t poured on top of the shot or so, easy.
toastees (Don't use real Cheerios, they're 3x as expensive! Wink

)

The other stuff is best placed below the shot (felt, foam, cardboard). There's no reason to pay for OS or nitro cards to stuff into wads to fill up space.

Once you start noticing and collecting "wad filler materials", it can become a whole new adjunct to your hobby, and isn't near the sickness that endless collecting of used hulls is... That's what I tell my therapist.

If you are using a mec loader check your pre crimp. According to mec the pre crimp should have an opening about the diameter of a primer. I had an awful time with 3/4OZ 12GA loads terrible dishing. I corrected the pre crimp as mec recommended and the dishing went away and I get perfect crimps.

well skeettx, I tried the cheerio thing and it worked like a charm. 1 cheerio, 1 oz shot and the z16 wad crimped just fine....

I have a lot of sg16 wads coming, but I just couldn't wait! what can I say? I'm impatient when I get a new toy.
