Double vision, Is that last load with 572 or GD? This is the one I sent you from yesterdays chronoing
2 1/2 in RST
w209
15.3 GD
SG16
7/8oz
1143,1149,1170,1195,1177 for 1166 avg
If I'd have used the CH209, it probably would have been much closer to avg fps of yours

Because of our previous conversations about it, I switched from 5 to 3 ft

Mid South has 8#ers in stock right now . (572)

I just chrono'd 5 rounds figured I'd post results:

Cheddite hull cut to 2 9/16" brand new hulls.

Ched primer

21.0 grains of 572

Sg16 wad

"1 oz 7/12" actually 425 grains drop from MEC

full crimp, 6 pnt about .055" avg

‐‐-----------------------

Results:

1262 fps avg

10SD

26 fps ES

Faster than expected no doubt due to 2 3/4 recipe in 2 9/16 hull
Forgot warm up shots - 1 and 2 were easily the slower shots, with warm
Up shots probably get a tighter spread.

Will drop to 20.0 grains and hopefully it stays tight. I'd like a pheasant load 1220 to 1240 fps and tight SD......so far so good.

Good work, makintrax73.

The SG16-S wads that Gull are sending me should arrive sometime today.

My goals are a 1 oz. load in the 1150-1175 range in a 2 1/2" hull.

Once I get things dialed-in a bit I'll send them off for testing and post the results.

Update:

I received the SG16-Short wads today. Thank you, Robert.

Things are looking good. The short version of the SG16 yields a much better stack height and the crimps are good without adjusting the reloader. That's saying a lot with all of my recent fiddling around with my Sizemaster's crimping stations.

I loaded up 6 rounds each of Cheddite and Federal hulls.

The Federal version did have a little taller stack height and it benefitted from firm wad pressure.

All of the loads are 2.5" hulls using 20.0 gr. of 572 powder, 1 oz. (437.5 gr.) lead, and the SG16-S (short) wad.

The Cheddite loads are using the common Cheddite 209 (CX2000) primers and the Federal loads have Federal 209A primers.

My guess is we'll see the low 1200's fps. I might load up few with with 19.0 and 19.5 gr. just to get a better feel for the low end.

Tomorrow is looking stormy around here, so hopefully I can get everything chronographed by the end of the week.

Double vision: welcome sir, glad they made it. Those look pretty damn good. Can’t wait to see the results.

Decreasing to a 15/16oz payload might be an alternative for the SG16 wad. I've done that with other loads to get a better crimp. The result would be and increase in fps and decrease in psi. Just saying it's an alternative consideration for those of use who don't have a supply of the SG16-S wad.

In general when I had loads tested by Tom the Z16 wad in a cheddite hull would have higher fps and lower psi than the same load with an SG16 wad. Not sure how the different wads will impact results using 572 powder. The chrono results posted in this thread would indicate that its likely to be the case with these loads.

Looking forward to seeing the test results as I have been using 572 with fiber wad loads and like them but I also have several bags of SG16 wads so it would be nice to have a tested load for those.

Agree about Z16 wad patterns....I prefer the SG16....although I'm mostly transitioning to fiber wad loads these days I still need to use up the supply of SG16 wads. Not sure what PSI difference would be between the SG16 and SG16-S wads. Whatever wad you use for testing is what I'd load.

I shot the first two rounds of Sporting Clays with that 1 oz. load in my 1100 with a modified choke. I have to pattern these loads the breaks were pretty impressive.

You folks gotta stop messing around with loads and try this stuff.

Just need to load up one more combo, then I'll take them all to the range for a preliminary speed test. After I look over those results i'll pick out 2 or 3 loads to send in for lab testing. I'm still on it, but life is cutting into my time.
