Omega trajectory chatrts??

[Flatlander.54]

Been looking for trajectory charts for the T/C Omega. Im using 250 grain Shockwave spire points and 777 (3 pellets). If anyone can help point me towards some info I would be greatful. Thanks.

I used the BC on Hornady's website and the velocity listed in my Omega manual for 150 gr load for a 250 gr bullet to calculate this. I tried to get it close to 3" high at 100 yds. My program does not let me specify 3" at 100 yds.

200 yds   -7.42 in  1285 fps   916 fpe  0.392 sec   26.34 in   6.87 in   12.00 in

This calculation uses the data given in a 250 SST ad in a magazine. I think it's way too high a muzzle velocity but include it here for completeness. I again tried for a 3" high at 100 yds zero.

I also shoot three 777 pellets with the 250sst. My chrono averages right at 2150 - 2170 for 250 sst and Barnes.245 spitfire out of my two omegas. These two projectiles shoot to almost the same point of aim at 100yds. I have to spit patch between each shot to get a 1.5"group.
    I have reloaded my Omegas in the field after killing deer with both projectiles it can be a struggle, make sure you have a good bullet starter with you.
     I prefer the Barnes .245 spitfie over the .250sst seems to penetrate and leaves excellent exit wound without blowing up inside the deer. Either load very lethal.

For a 250 Shockwave/SST at 2150 fps. This one looks like a real easy yd load. Aprox 3" high at 100 yds and 3 1/4" low at 200. I'd verify that at the range but it looks good.

I shoot  a 50 caliber Omega. One of my pet loads is 95 grains by volume of BlackMag 3 and a Precision Rifle Duplex Sabot with 175 grain Dead Center bullet. I am sighted 3 inches high at 100 yards, the drop at 200 yards is 5 inches. I have taken 3 bucks, 2 does, two coyotes and a few hogs with this combo  at ranges as close as 75 yards to over 200 yards with  excellent results.
