What kind of shot groupings should I be able to get with this combination of Equipment and Ammo at 100 yds? Assuming me the shooter is flawless.

Went to the range yesterday and zeroed in the scope and wasnt happy with results at 100yds. Trying to figure out how much of the problem is me.

1.5" or less.  Come back and tell us how it actually does.

Most 55gr M193 equivilant ammo is designed to hold 3" at 100 yards with a 20" milspec chrome lined barrel, it's not match ammo.  You may be able to tighten the groups somewhat by using your scope instead of iron sights though, but I wouldn't expect MOA.  
Some folks claim to shoot very tight groups with M193, and I'm not disputing their results, but it's not designed to shoot MOA.

It depends on how lucky you were at getting a shooter for a rifle.  Worst case 3 MOA and best case just a tad under MOA.  I would guess 1-2 MOA.

OK

What I got Tuesday afternoon was about 3 moa but I felt I might have been a bit shakey, so maybe some of it was me.  I was sure hoping for better than that though.

I'll try again tomorrow and post my results. I also have a small quantity of some New Georgia arms 55 gr ballistic tip ammo thats suppose to be very accurate, I might give that a try as well.

Thanks for the feedback

All I ask for at 100 yards is m.o.c. (minute of crainium), any farther than that and minute of torso is just fine.

I tend to expect about 2MOA.
