Well I got time to do some shooting. I took my Omega and a NEF Handi Rifle, 308, I won it. The 308 shoots quite good but my Omega shoots better. I shot both 250 gr and 300 gr Shockwaves. My Omega is starting to loosen up ( about 250 shots now) , The Shockwaves all loaded much easier now. My gun definately likes the heaver bullets better. I used 110 grs of 777 with the 250s and 120 grs with the 300. I recovered quite a few of them from the sand and some looked pretty good and others showed complete seperation from the jacket.
I also shot about a dozen Barnes TMZs, 290 gr. I got to shoot from 50 yds and 100 yds, measured by laser range finder. I was able to get about 1 1/4 inch groups at 50 yds and about 2 inch at 100, not great but there was a fairly stiff breeze. ( at least thats my excuse).
I recovered eight of the TMZs out of the sand. GREAT performance! All of them expanded perfectly, full mushroom of the petals. I weighed them and they ranged from 289.4 grs to 290 grs. If they perform this well on game they should be great for anything from deer to elk and bear.
