Nothing wrong with factory STS in 410 or 28 ga. The STS 410 offers more case volume, so easier to get Max allowable shot at higher velocities.Glad to see Remington is back up and running making ammo again but they just do not understand what makes a good .410 shell (or 28 gauge for that matter).
I am going to start reloading the same hulls , Remington with 1/2 ounce of shot which wad are you using. ????I have my shot bar tuned to consistently drop 1/2 ounce of shot. When reloading Remington hulls, there is still still plenty of room for more shot. The AA hulls are nice and tight.
.....Consistently tuned to WHICH BRAND of shot? As shot gets harder, it gets lighter. REM STS are known to have the hardest, and therefore lightest, shot in them....so they can put more BB's in. That's why so many top 410 shooters like using STS.I have my shot bar tuned to consistently drop 1/2 ounce of shot. When reloading Remington hulls, there is still still plenty of room for more shot.

Thankyou for that information. My sizemaster will be here in a few days. I am loading for just fun and enjoyment, being locked down because the virus thing etc. Used to load in the 1980's for shotgun. Have been loading metallic for 40 years and now with a new Mossberg over and under in 410 I want to have a little fun.I’m using the clay buster replacement 1/2oz wad p/n cb5050-41HS which is the similar wad to Winchester WAA41HS or the REM SP410.
I load this wad into 2-1/2” win410 new style hull, Rem STS and Rem Nitro hull. Not a good fit in the 3 inchers.

NSSA allows up to 232 grains Max of shot in a 410, where as a 1/2 oz is 218.8 grains nominally...so feel free to put more shot in them!!
I started out at 17.3 grains 300MP in my STS reloads, but was getting over 1400 FPS with them. I backed down to about 16.5, and really happy with how they’re breaking bird!I get 245 gr of shot in STS hulls using the PC orange wad. I don't shoot any competitions so it's OK. Using 12.8 gr of Alliant 410 or 17.4 gr of 300-MP it boils targets.
