RE: T/C Omega
I love my Omega!!!
I found mine shoots 250 Gr Shockwaves with 2 50 Gr pellets of T7 with great consistency, and holds a 1 1/2" group at 100 yards.
Second and third shots are a little tough to load if I dont swab but doesnt seem to effect accuracy unless I shoot more than 3 or 4 shots without cleaning. So, follow-up shots if needed are definately doable, however haven't need a follow-up shot yet.
Good Luck and let us hear how you are getting on
