will these loads be acceptable?

save those shells for squirrel hunting maybe
with the setup you have,you need to try some Federal Flightcontrol #6's or 5's

This would be a good idea out of that fixed full choke.  Get you Federal Mag-Shock 3" 2oz #6 shot and I'd bet it will shoot much better than those Remingtons.

I just saw the yardage you wrote on the targets...45 and 50 yards?!! I ALWAYS start at 30 yards after I establish POI with a cheap target load of 7.5's, then move back 5 yards if 3 shots at 30 yards show a good pattern. The patterns are very poor, but I think you are asking way to much of your gun/shell/choke combo anyhow. Give that combo a try at 30/35/40 yards. In my opinion a 40 yard shot shot has always been considered a long shot no matter even if I consistantly put a few dozen pellets in the head and neck.
