Swampy16,

There are a few things that will help out.

The first is I don't use a MEC bar because they always throw light especially with magnum shot. I use the Multiscale charge bar. I am actually dropping a full 1 oz.

I only use enough wad pressure to just bump the wad pressure indicator.

Be sure that you have the same wad that I am using. There are two different Gualandi 16 gauge wads. The easiest way to tell the difference is by the small protrusions in the overpower cup. You want the one on the right. The wad on the left will sit farther down in the powder charge especially if you use a lot of wad pressure and will create the dished crimps.

Ballistic Products sells both 16 ga. Gualandi wads the correct one is the SG16 - the SG16S is supposed to be shorter but.......barely. The difference is in the amount of protrusions in the overpowder cup, and that does affect how nicely the crimp is formed.

You can get a good crimp using the SG16S with 1 oz. loads, but it is much easier using the SG16. Especially in Federal, Cheddite (Winchester), RIO and other hulls with similar capacity.

I am not sure which wad Precision Reloading sells....the picture looks like the SG16S.

I may not be able to get back at it til this weekend but Iím using a 600 JR. I have a universal charge bar I may try using to make sure Iím getting a full ounce of shot. This site is a great help. Thank you all. I will update as soon as possible.

you may or may not have one of those digital scales . BP has them on sale occasionally and they are SSOOOO useful . You can dial your powder and shot right on !! Thats where the light really comes on about what the bars really do .

I have both a digital and beam scale. Iíll try to dig into again this weekend. Iím a landscaper so things are nuts right now, even in the midsts of the virus.

You are using the totally wrong hull. The 1 oz load has been intended for 2 1/2" 16 ga hull since the beginning of time (technically the 1800s). Use the SG16S wad with 2 1/2" hulls and you will have the CORRECT original combination. You also need to learn how to adjust the MEC crimp starter, crimp tube, and the crimp punch simultaneously, I will allow it can be tricky.

And all you guys that use fillers, wads, cards, felt, breakfast cereal, etc.,for 1 oz in 2 3/4" hulls, come on, what's with all that?? The 16 ga is meant to be a lightweight 2 1/2" chambered gun with 1 oz of shot!! U.S. makers went with 2 3/4" back in the 1900s as a desperate crutch so 16ga shooters could shoot 1 1/4 oz (or more!) to keep up with the the 12 ga big boys. 2 3/4" hulls are so last century. Lose them!

Brewster11,

Many companies use the 2 3/4" hull for 1 oz. in the 16.

There is plenty of data for 1 oz. loads in 2 3/4" hulls for the 16.

If you look at my posts they are proof that the component combination the OP asked about will accommodate a 1 oz. load. No special adjustments, no fillers, nothing but a good load.

I routinely load 1 oz. loads in any and all 2 3/4" hulls currently on the market.......and I am certain that there are plenty of others here that do the same.

I load these 1 oz. loads on both a Sizemaster and a 9000G16.

Mark,

Yes, it can be done, I've loaded probably a thousand myself...but why?
It's like fitting a size 10 foot into a size 11 shoe. Lace it down tight and you hardly know the difference, but its an inferior fit.

The OP has a problem. And his problem will go away and never come back if he uses a 2 1/2" hull.

What I've found is 2 3/4" Cheddites can work fine with 1 oz and SG16, but 2 3/4" Fiocchi hulls do NOT in my experience...the plastic is flimsier and the crimps eventually cave in. I suppose with more crimp adjustments the Fiocchi might be make to work as well.

But why bother? ALL the different Euro hulls crimp fine with the same identical crimp setting for 1 oz with the 2 1/2" hull and the SG16S, because that's exactly what it's made for.

OK, I confess that I don't like the 2 3/4" shell...to me it's like those cheap old overbored VW cylinder and piston kits sold by JC Whitney, remember those? They were kind of ridiculous unless you were building a DIY dune buggy.

Kind of the same deal here - does anybody really need to shoot 1 1/4 oz out of a 6 1/4 lb 16 ga? Because that's the only real reason to use 2 3/4" hulls.

One might say the 2 3/4" is needed for 1 oz notox loads, but then again roll crimps will handle that in a 2 1/2" hull.

Cheers
B

The only reason 2 1/2" shells exist is because of the 20-30 year transition period of mainly brass shells did not require the space. Once paper shotgun shells became widely available around the turn of the century, the world nearly immediately went to 2 3/4" shells, and has maintained superior popularity for some 120 years.
