Does anyone have hands-on accuracy data between the 250 and 300 Shockwaves using the .50 Cal Omega? And if so, at what yardage, group info, etc?? Just curious, getting ready to go to the range this weekend.

None of my Omegas shoot 300 grain bullets as well as the 250 grain. Not a big difference at 100 yards the 300 grain groups would be 2 to 21/4" as compared to 1" or less for the 250s.

==================================

Some of it depends on powder charge & what powder you're using. Bullet speed at ignition can determine which bullet is right for you.

You really need to try them both at both the shortest & longest yardages you shoot. Every rifle is different -- even the powder/bullet weight & primer selection plays a part in this.

Poster Omega50cal likes 150 grains (3 pellets). If you shoot two pellets, with a slower bullet takeoff compounded by less powder energy & heavier bullet weight, the 300 may work better for you than he.

The bullets are relatively inexpensive & the ones that don't perform as well won;'t go to waste. They will still either be acceptable for hunting or easily sold to someone else because of their popularity.

It would be interesting to hear any apples to apples powder volume comparisons andaccuracy differences with the 250 and 300 SW, using the same amount of powder.

An inch or two either way... just like Omega50 expressed in his post. The heavier one will have slightly more energy at impact. The 200 & 250 are more inclined for deer-type game.

Well, I have tried them both with 130 grains of Pyrodex pellets - in my Black Diamonds and new Omega. The 300 shot acceptably, 250 shot great. Point of impact was very close in all three guns, with the 250's hitting an inch or so higher in each case. I shot an elk last year with the 300 grain and it worked pretty well. Afterseeing the picture (on this site) of the hole through a moose's shoulder put there with a 250 grain Shockwave, I'm looking forward to trying the 250 gr. SW during the New Mexico elk season a little later this fall. I'm betting it will work fine.

I haven't shot the Shockwaves, but I have shot 340 DC, 300 Nosler Partions and 300 SST by Hornady in my Omega.

340 DC, 100 gr T7 Pellets, 100 yds, 2 inch groups
340 DC, 110 Loose T7, 1704 FPS avg (3 shots) 20 yds
300 gr Nosler Partion, 100 gr T7 loose,1748 FPS Avg, (3 shots) 20 yds
330 gr Hornady SST's, 100 gr T7 loosee, 1758 FPS Avg, (3 shots) 20 yds
All shot reasonably well for me. All in the 2-3 inch size groups.
I sailed a 300 gr SST over the chrony at a 100 yds last weekend and it registered 1558 FPS at that range. Using the Point Blank program that turned out to be a BC of .240 with over 1600 FtLbs Energy at 100 yds.
Using that load for the SST's I got about 2 inch groups at 100 and 3.5 - 5 inch at 200. Pretty windy day and maybe some shooter hicups to explain the flyer the main group (3 shots)was under 3 inches.
Cheers,

Good report Aaron and very much my findings. The 300 SST/SW has a BC of .240 as compared to the 250 at .210 or there abouts. As I said above I really like the additional accuracy that the 250 gives me and Sandi and I have killed deer and moose beyond 200 yards with the bullet.

To anyone: I'm curious why someone would choose a 300 grain or larger bullet. Now don't anyone take offence I'm just asking that's all.

When I started in this game bullets weren't terribly aerodynamic and speeds were slow. At the advent of sabots and bullets like the SST I really took a close look at the performance envelope and came to some surprising conclusions. The venerable old 30-30 launches a 170 grain bullet at 2000 fpsand you are beating a 308 hard to get a 200 grain bullet to 2400 FPS. The 30-30 is one of the great all time game killers. A 250 SST out of my Encore hits 2200 FPS pretty easy and with great accuracy. The bigger bullets kill very well no doubt about it but why would you need to use a 300 grain or larger bullet to kill that 200 pound whitetail that every year dies by the thousands from 100 grain bullets out of a .243?

Each to his own and I understand personal choice very well - I've spent most of my life swimming against the current. The thing I'm getting at is so many people especially new people to the sport believe that these huge bullets are needed as if the ML won't kill that little deer with anything less.

Personally I am looking for the most accurate bullet out to 200-250 yds. Doesnt matter to me if its 250 or 300 SW. I believe one of these two SW's (perhaps both) will be the answer I hope. Seems as though I seen where someone was using the .50 cal Omega indicated that the long distance accuracy (200-250 yds) was notable better with the 300 SW, havent confirmed with mine yet.

I went with the 300 gr.SST last year because Hornady recommended them for elk and moose. I got pretty good penetration on an 800 lb. bull elk. Bullet entered the middle of the chest on the right side and angled into the shoulder on the left side without exiting.

The thing to remember about big bore bullets is that the sectional density of a short fat bullet is not that great. Nor the ballistic coefficient. Although sheer weight has its own merits - like in the case of the .62 caliber round ball.

My plan this year is to try the 250 gr.Shockwave later on in New Mexico's elk season. I'm betting it will work fine on a broadside rib shot. I even wonder about the 200 grain Shockwave. It is a .40 caliber bullet, and probably has a sectional density comparable to the .451 250 grain Shockwave.
