Double Vision: got your PM I will get them sent out tomorrow. I'M not sure I have the wad that Mark is talking about. It may be that wad and not the SG-16S. Let me check tonight when I get home. I may very well have both. I will update later

The Gualandi BRG 16/21 (SG16) is on the left. Middle is the Baschieri & Pellagri Z2/M 16. The Gualandi BRG16/18 (SG16S) is on the right.

As you can see in the second picture the Z2/M 16 will sit the lowest in the hull and has a taller shot cup.

All 3 wads will generally produce the same velocities and pressures, using the same components. Probably an exception or two, but not many.

I'm currently trying to fix and outdoor faucet and I'm a much better reloader than plumber.

Hope you got the faucet fixed. Sent you a PM.

RGull, I amazed myself and fixed the faucet. Probably saved myself a couple hundred or more that can now be used for more important things like reloading supplies.

makintrax, good to know the SG16-short is working. I see your slightly under an ounce at 425 gr. but not much.

I'll take one for the team and send in 2 or 3 shorty 1 oz loads with 572.

The first 2.5" hulls I tried with 20 gr. 572 were Federals and the regular SG16 wad. They crimped perfectly.

When I tried the same with the 2.5" Cheddite hull they just seemed a bit overstuffed, high stack height.

So...I'm thinking of getting the Federal/SG16/Fed 209A/20 gr. 572 tested.

Also test a 2.5" Cheddite/SG16S/Ched 209/20gr. 572

Could also send the above Cheddite hull load with a Z16.

This should at least give us a baseline on these Hodgdon loads put in the short hulls.

Thoughts?

I like the way you think.

These are the 2 1/2" Federal hulls with SG16/CCI209M/20 gr. 572 innards.

I originally wanted to have this load tested because I have a couple hundred CCI 209M on hand, but after thinking about it I'd rather test the load with Federal 209A primer. The Federal 209A is generally more available over the long haul. I'm still going to chronograph these CCI 209M loads just to see.

2 1/2" Herter's-Ched/Z16/Cheditte 209/20 gr. 572

Mark was right about the Z16 being a good fit. I could fine tune the crimp, but the stack height was right on the money. The crimp can be prettied-up later.

I'm heading up to a little country range to start some preliminary chronographing before I send anything in to get tested.

I haven't looked yet but wonder how much pressure difference between the 3 wads?

Here is some preliminary data. I'm trying to get a feel for these 572 loads before I invest in any testing. My goal is a 1175-1200 fps 1 oz. hunting load for an older gun. It doesn't matter to me if it's 2.5" or 2.75". I load my hunting loads on a Sizemaster.

Powder and shot hand-weighed on a calibrated scale. All 6-fold crimps.

First up is a 2.5" Federal load

2.5" Federal
SG16
CCI209M
20.0 gr. 572

6 rounds and the went 1203, 1221, 1246, 1194, 1200, 1174 for a 1213 average.

With this combination in a 2 3/4" hull Hodgdon states:

19.0 gr. 1165 fps 6900 psi
21.3 gr. 1220 fps 7900 psi

---------------------

Next is:

2.5" Herter's-Cheddite
SG16
Cheddite 209
20.0 gr. 572

1219, 1158, 1198, 1224, 1204, 1197 for a 1200 fps average.

Hodgdon's 2019 version in 2 3/4" went 20.5 gr. 1204 fps 6300 psi

---------------

Next:

2.5" Herter's-Cheddite
Z16
20 gr. 572
Cheddite 209

Only 3 rounds for a quickie.

1253, 1240,1263 for a 1252 average.

----------------

I also checked my usual 2.5", 7/8 oz. target load. It's based on 3/4 oz load fn16ga had tested.

2 1/2" Cheddite
Cheddite 209
SG16
15.5 gr. GREEN DOT
3/4 oz.
1177 fps 7400 psi

I've been using the same load, but I drop 7/8 oz. (I think he does also) but it hasn't been tested , so today I wanted to check the velocity. I really like the load for clays.

The rounds below were not hand weighed, just regular production loads on my Sizemaster. Unaltered MEC bar, so no doubt it's throwing West Coast Mag 8's a bit light.

With 7/8 oz. it went: 1191, 1210, 1203, 1192, 1190, 1180, 1189, 1200, 1174 for an average of 1192 fps.

So, if I'm reading this right there is a slight fps increase with the z16 and not much difference in the cci and cheddite primer in recorded fps. I would assume there is also a slight increase in pressure with the Z16 vs SG16. Good work by the way. Much appreciate your time and effort.
