Semi, I have yet to figure out why TC dropped the Omega so abruptly! They were really good rifles.
Have you ever considered using a PBR (point blank range) sighting technique. I use a 3" PBR (with a muzzleloader) and with that I should never be higher or lower than 3" through a given range. In most cases with a muzzleloader it usually computes to about 3" high at 100 and 3" low at 160/170 yards. Of course that varies with the load and the bullet.
This is an ballistic sheet computed using a Lehigh 452x240 shooting a 120gr. V of BH - with a 3" PBR built in.
