I loaded some 2 1/2 ched hulls with 19 gr unique and 7/8 oz bp sg16 wad.
Based on load data I had from years ago, ejected out of sweet with more authority than expected. does anybody have published data on something close to this, I may have made a mistake? Wouldn’t have thought so since plenty of data with 20gr universal same load? No chrono here or I would check.

I can't help with load data, but what do you mean they ejected with more authority? A sweet 16 should eject the same distance no matter if it is a 7/8 poof load, or a 1 1/4 ounce magnum.

You are in the ball park for safety and function using
"The Handbook of Shotshell Reloading"

I would insure you have the shotgun set on the heavy and not light

It threw the shells farther and had some kick.
Seamed much stronger than my Hodgdon universal load with 20gr same other components.

Thanks Mike. Everything I had said should be ok, I only shot 2 may back off a grain and see if they still work and are soft enough for my doubles. Was trying to use in both and burn up some 25 yr old unique for next season.
Bought all the universal, international, green dot I could find for the future.

Under Low Pressure load data I found:
Cheddite hull, SG 16 wad
1 oz load
18 gr Unique
1165 fps @ 8200 psi
This was in a 2 3/4" hull, but with 7/8 oz will fit fine in a 2 1/2", try dropping to 18 gr

If you are actually using 19.0 grains of Unique and 7/8 oz. of shot, you are shooting a very mild load. My guess is about 1225 to 1250 FPS. A very standard, nothing out of the ordinary load.

You must have something else going on. How much lube do you have on the magazine tube? Is the ring on the mag tube? Has the recoil spring broken? Having used light loads in a (original design) Sweet 16, I ran it with a drop or two of light oil (RemOil or Breakfree CLP) and the ring set for light loads.

30 weight oil and wiped off on any auto 5 magazine tube. REM oil is ok for the outside, but not inside. Has Teflon in it. The real clp will work in a pinch, but nothing like 30 weight oil.

RGuill96971,

Please do not take offense.

30 weight is fine where or when it is warm out. Not so good where it gets cold during hunting season and you are using mild 7/8 oz. & 1 oz. loads.

Even when I lived in CT it got cold enough during woodcock season that I had to use a light viscosity oil with light loads to get my Sweet to function reliably.

I should have mentioned the part about it being cold in my post.

mark:
None taken. And I agree the cold weather does play a part, then I would go to clp. Anything with teflon in it just kills the purpose of the friction rings doing their job. When it gets warm it becomes sticky. not what you want in a long recoil.

I have data for a similar load, but bear in mind that this is a roll crimp load. Fold crimp will raise pressure (by how much, seems to vary a lot based on data I have seen).

Fiocchi 2 1/2" hull
7/8 oz. lead
20 gr. Unique
Fio 616
SG16 wad
1090 fps
8,100 LUP

Agree with Skeetx. If you start feeling stingers on the fingers of your trigger hand, it means the friction ring is in the wrong position, i.e. light setting. Make sure the ring is in the the forward (heavy load) position.

Does taking a load designed for a 2 3/4" hull, the loading it in a 2 1/2" hull, increase the pressure?

IE: Does a shorter hull result in higher pressure for a given load?

John Singer,

Yes but..........it is variable to each load. Fold crimp vs roll crimp.....and it isn't going to be a huge difference in most cases.

____________________________________________________________

An original A5 Sweet 16 generally requires a 1 1/8 oz. or a fairly stout 1 oz. load to cycle the gun on the heavy setting. The load in question, as long as it truly is being reloaded properly, is a powder puff load and SHOULD NOT cycle a real A5 Sweet when set for heavy loads.

Something else is going on with this gun/load.

I lowered to 17.5 grains unique ejected on light setting perfect, also used some r16 wads in place of sg16 and also ejected and felt same.
I only use Lucas extreme gun oil these days.
Will be great for both old doubles and a5s.
