Fellows I tried out my new Omega today with 250 Shock Waves and APP I shot every 10 gr. from 100 to 150 my smallest group was 3/4 inch my biggest was 1.2 inch.Since I lapped the barrel and changed powder I am very happy with my 160 dollar purchase. Shot the 200gr. Shock Waves too they ran from .75 inch to 1.00 inch. Lee
