From what I've read on this site and others most guys with Omegas are having a hard time with this bullet and the 150 gr powder charges. It ranges in having bullets fragment and having not very good penetration. I personally think that if you use 100 gr charges the bullet will hold up just fine. All my deer have been with this charge and have been bang flops. If you must shoot 150 gr charges then you might try the Barnes bullets as many swear by these bullets and from what I've seen they hold up like no other. The Schockwaves work for me so no need to switch as my guns love em.
