A coupla opinions....
In any 12 ga shotgun weighing less than 7 lbs, I'd stick to loads of no more than 1 1/4 oz, and preferably less, due to recoil.
Frankenstein's a little bit more than 7 lbs, and most turkey loads feel like"Being in a car wreck" to quote Bob Brister. The stock fits(tho short), good pad, my form is good and I'm not sensitive to kick. Nevertheless, I know when the shot goes off. A heavy diet of those loads and I'd reach for a 9 lb trapgun or "Serious" Shotgun.
The Brits wrote the Rule of 96, which states that a shotgun is best weighing 96 times what the load does.Much heavier, too much weight, much lighter, heavy kick.So,a 1 oz load should be in a shotgun weighing 6 lbs. That's ASSUMING good fit, which the Brits wrote the book on.
Heavier loads almost always require heavier shotguns for shooter comfort. Unfortunately here in the US, most folks pick a 12 ga for its versatility, forgetting that specialized shotguns will do better at specialized jobs. Waterfowl, turkey, and slug/buck loads pretty much demand
an 8 lb shotgun, up.
Upland guns are best at under 7 lbs,IMO.
I could make a good case for building an upland load of 1 1/8 oz, using a trap load recipe and substituting only different sized shot,say 6,7 1/2 and 8s. 8s for quail,woodcock and waterhole doves, 7 1/2s for quail,doves and even preserve pheasants as a first up load, backed by 6s, and so on. And I might go with hard 7 1/2 shot but soft 8s, just to adjust the pattern a mite.
As for this Stoeger, I see it as a fun gun to carry a lot and shoot some. Maybe it's not a Sporting Clays shooter or a trap gun, but a fun little takealong gun that's sudden death on small bird, small shot, close in situations. I'd have fun setting it up with the balance centered between the hands and playing with that stock fit until it fit my vastly different from average body.I'd use generic trap loads for most of my shooting,pack some 8s for quail, and a few hard 6s for ringnecks,etc.
And it probably wouldn't have a choke tighter than Modified.
