As I posted before the 250 gr. Shockwaves are very tight in my Omega, that's what got me interested in experimenting with different components. I'm also going to try different projectiles. I'm interested in the Dead Centers, gotta look around for some. Another thing I've wondered about is the tail on the Hornady SST sabots. Aren't the center holes on the Hodgdon pellets supposed to aid ignition? If so it would seem that the Hornady sabot would hinder this.
