AA S410 ERB / .22 Pellet question

[TCups]

I picked up the AA and just for kicks, loaded up 20 Beeman Silhouettes to shoot a 10-Meter off hand score.  I figured the the Silhouettes would punch a nice clean hole.  Then, I started to load up some H&N Match wadcutters, but remembered that these are not recommended for the AA 410 as they can damage the seal.  But now it occurs to me that the profile of the Silhouettes has the same sharp edge (perhaps a sharper edge) than the typical wad cutter.  They shot well at 10-meters and indeed punched very nice, clean holes in the target (score180/200), but I suspect that these, just like the wad cutters, might damage the breech seal.  Any one know for sure if these should not be used in the AA 410?  Thanks.

There is  website/dealer that sells AA repeaters and at the end of the page....they recommend some types of pellets....I believe they were all domes.  CPHP, Crow Magnums etc...and quite a few others......but I haven't been able to locate that webpage yet.

I also picked up a single shot tray and two new mags for the AA 410.  Using the single shot tray, I wonder if it is OK to load up wad cutters?

From what I read....and understand (?)....it seems there are 1 or 2 O-rings inside the breech.....and you don't want to ruin or make micro tears on them.  So even if you load a pellet with a rough or angular edge by using the tray....it might still rub the O-ring(s).   I could be completely wrong......
