I have a quick question to anyone who has played around with the 20 ga reloads to the extreme side, most manuals list 16gr 800x under a waa20 wad with 7/8oz 9300psi and Winchester primer(im using a cheddite as i found they are slightly colder) Has anyone loaded them up to the 11,000psi range? Seems all are limited to 1200fps and i like my reloads a bit faster and in 7.5 shot where i can only find 9's. Played around at 16, had a barrel full of unburnt powder, worked up till i seen pressure at 19 and 19.5 and found what patterned the best was at 18gr. The closest ive seen is 17.5 at 10,800psi but not sure what kinda pressures im working with if 18 is where i like it. Gonna chrono a bunch later and work from there i think.
 
2-3/4" 20 ga. : 18.0 gr. of 800X in the old Winchester Compression formed ( AA ) case, Win. 209 primer and an WAA20 wad.
Lyman lists this 7/8 ox. field load at 1270 fps / 10,400 LUP.

My favourite heavy field load for the 20 in 7/8 oz. is 17.5 gr. WSF, Win 209 primer & WAA20 wad for 1250 fps / 10,100 LUP

Something a little hotter is Hodgdon's " Longshot ". Win 20 ga. 2-3/4, 7/8oz. Win 209 and WAA20 ... 18.6 gr. for 1300fps / 11,700 PSI or with the the Windjammer wad,
20.0 gr. for 1350 fps / 12,000 PSI.
 
Chrony results and shotshell pressure don't always directly relate like rifle rounds do. There is a lot of laboratory data available showing how pressure can change drastically with only minor changes in velocity when dealing with shotshells. I wouldn't use chrony results to try to tell what pressure the load is producing personally.

For the info supplied, I didn't ... this is either Lyman's or the powder manufacturer's data, as the case may be.

Other than for waterfowl (...and lead is not permitted anyways ) I really see no great need for anything above 1200 - 1250 fps in a 2-3/4" 20 ga. 7/8 oz. load of 7-1/2's. .
More than adequate for targets, grouse, woodcock, huns, etc. For pheasant, a 1 oz. load of 6's will work better.
 
My target loads i prefer them up around 1300fps is what i was trying to go for, every time im back at 1200 or lower i miss alot more in skeet, sporting clays and 5stand gong for some of the longer shots. As for waterfowl right around 1400-1500fps works well for me, everyone is different. Also im not just using fps, using published data and comparing it to my reload when they say it does 1200fps for a such length barrel and im getting 1125 is a big difference. That way i can tell how fast, and figure where im at psi to see if there is room because the reload is slower then published.
 
For steel waterfowl loads ... speed is an advantage ... for Sporting & 5-Stand ... sounds like you need to swing a little faster or change your method of
acquiring forward allowance. I find no problem with 12 ga. 1-1/8 oz 1145 fps loads of 7-1/2's out to 50+ yards. Trying the same with a 20 ga. 7/8 load
of 7-1/2's even through a full choke may not give you enough pattern density no matter what velocity. Have you tried patterning your 7/8 oz. loads at
distance ???

Ive got good lead distance on the target, good shot patterns, I just like the faster FPS better. My 20 ga was just as i thought 17 grain 800x powder was only coming in at 1165-1180 and 18 grains 800x was at 1215-1230
