RE: TC Omega w/ NIKON BDC optic.
DropTine249
Quite often in fact more than quite often magnum loads (150 grain) will not give you the best accuracy - it will get the bullet there quicker and it will get it in the area... One of the reasons I have even looked at Nikon BDC ( I think that is the one that is set up for 150 grains/250 bullet) What if you do not shoot that load? I do use ballistic reticules but you have to detirmine the drop of your particular load. I shoot either 100 or 110 grain loads and they do the job quite effectively. i would suggest to you that you drop back to 100if you are using pellets and give that a try - I am sure your accuracy will come together. Here are my favorite loads for my Omega: Here are my most favorite loads as written in another posr... for Elk 100 grains T7-2f (loose) .458/300 grain(45-70) Nosler Partition PP, HPH-24 Sabot, 25 acp ignition for deer 100 grains T7-2f (loose) .451/260 grain Nosler Partition HP, HPH-24 sabot, 25 acp ignition These bullets are expensive so for an alternative and a bullet that I can shoot paper as well as big game - I am moving to the Speer Gold Dot Bonded HP's, either the .452/300 for elk or the .452/250 for deer. Same powder load and sabot. I buy all of my bullets in bulk reloaders boxes and order the sabots separately... trying to keep cost down. Buying bubble packages of bullets and sabots can really add up. Good luck with your new gun... |
RE: TC Omega w/ NIKON BDC optic.
You might experiment with your gun and load to see what the combo will do with a 120, 100, or even 80 or 90 grains of powder. Its not about getting good groups, its about finding that "magic" combination of powder and bullet that your rifle likes. What I'm about to suggest is time consuming and kind of expensive but its what you need to do. Go buy afew different types of bullets and just experiment.

RE: TC Omega w/ NIKON BDC optic.
I have the exact same set up but only using 100 g of powder pellets. I don’t think a magnum load is really necessary unless your gun needs to shoot that. Plus the thing kicks like a mule and if you’re not in a shooting vice that helps keep the recoil down you will not be able to shoot long and more importantly consistent.
I like the Nikon scope but if read the directions there is a way to tailor that scope with the loading that you like. If you do not have directions anymore just let me know and I will paste them. I agree that if you tame back on the amount of powder the groups should be closer. I have been using the Shockwave 250 and seen decent shooting at 100 yd’s but I hope I can get the pattern to tighten a bit more (2 inch groups at 100 yd’s) haven’t went any further then that yet due to the limitation at the range. Plus the gun is still very new only 25 round shoot through it so far. I have some Barnes bullets and the box says that they need 150 G of powder but I only used 100 and didn’t even hit the paper when I just hit a bull’s-eye the shot before with a shock wave 250. Crazy how this works! |
RE: TC Omega w/ NIKON BDC optic.
Keep your setup but change/experiment with different powder levels. Once you find an accurate consistent load, set a target at 100 and shoot a group with each aiming point to get an idea how high each is over the center cross hair group. Then find out from others shooting the same load (or by chronographing) what the velocity is and put the data into a ballistics calculator to determine the distance each aiming point is regulated to for that load. Then your good to go. I hope this makes sense and helps.

RE: TC Omega w/ NIKON BDC optic.
120grs. of T7 will shoot to the same POI as three pellets T7,or Pyrodex. We just converted a friend over to the three pellet load. He shoots a Omega. The gun drives tacks with either 100 grs. pyrodex,or three Pyrodex Pellets. If you are shooting under 150yds. there is no need for the three pellet load. If you are planning on "reaching out there" 200-250yds,yeah you need the added velocity of the three pellet load. We have allot of open bean?corn fields here. So we set our guns up for long range. More than one Buck was taken last year at over 200yds. A bunch were taken in the timber line at less than 100yds,too. My wife shoots 90 grains of Pyrodex,and limmits her shots to 125yds or less,it's whatever you are comfortable with that matters. Ron

RE: TC Omega w/ NIKON BDC optic.
The one load that might help you out is the 200gr SW if your gun wont shoot that with 150 gr then its not going to be one of the few that have the right harmonics for any 150 gr loads. Lee

RE: TC Omega w/ NIKON BDC optic.
If you are shooting the T/C Shockwaves and are having accuracy problems keep in mind that the 250 grain bullets come with two different types of sabot and that the sabot could be the problem. I was shooting my Encore and wasn't satisfied with the accuracy and was shooting the 250 grain bullet with the "yellow" sabot, then I tried the same load with the 250 grain bullet with the "black" sabot and I cut my 2 1/2 inch group down to 1 1/4 inch by changing only the sabot. Hope this helps...
PS: my load for my T/C Encore .50 cal is 3x50 Pyrodex pellets, 250 grain T/C Shockwave "black" sabot and my primer is the VariFlame system using Federal small rifle primes. I'm consistently shooting between 1 and 1 1/4 inch at 100 yards. This load also took my cow elk at 52 yards and I recovered the bullet on the off side shoulder. |
RE: TC Omega w/ NIKON BDC optic.
What is the difference between the Shockwave 250 grain sabots with the black jacket versus the yellow jacket?

RE: TC Omega w/ NIKON BDC optic.
You might try Pyrodex pellets instead of the T7. Just switching powders might help your groups - you never know until you try.Your ballistics should be very similar so the scope's settings should still be very close. That is all they will ever be - very close at best, so verify those circles/lines with actual shooting vs textbook calculations or manufacturer's claims.
And I would definitely advocate the use of loose powder as others have already suggested. Loose gives much greater flexibility for much less expense. In any case, you need to verify your trajectories with actual shooting. My Burris Ballisti-plex on the Umag has lines for various ranges. With one load I use (that is sighted 1" high at 100yds) the first line down is good for 150 and the second for 200 at 9X magnification. Worked out pretty well I think. I carry the rig with the scope on 3X but if I happen to get a good standing shot at 200 yards there should be time to increase to 9X and find asteady shooting position. If there isn't, the shot won't happen. |
RE: TC Omega w/ NIKON BDC optic.
The sabot is a different plastic, my gun shoots excellant with the original sabot and all over the place with the Super Glide.
As a suggestion the best of the Shock Waves for shooting flat and normally for getting good accuracy is the 50/40 200 gr it is also very good on the terminal end, if you were to shoot it with different loads at long range you might be able to find a combination that would suit your needs. Lee |
RE: TC Omega w/ NIKON BDC optic.
Drop tine,
I don't have the Nikon data on the drop they used to design the reticle but based on an approximation of the load using 2200fps as a velocity the aiming points are approximately the following when zeroed at 100 yards: Center= 0 (100 YDS) 1st circle = -3" (150 YDS) 2nd circle = -9" (200 YDS) 3rd circle = -13" (225 YDS) 4th circle = -18" (250 YDS) These are rounded but will be within about .5 to 1" of what you should see. If your velocity is a little higher or lower it will not make a lot of difference, i.e. +/- 100fps will make about a 2" difference in drop at 250 yards. I hope this helps. |
RE: TC Omega w/ NIKON BDC optic.
Drop Tine-How fast are you shooting? My Omega does the exact same thing if I shoot too fast.Try letting the barrel get stone cold between shots.Take a couple rifles and switch out. My Omega drove me nuts untill I read on this forum about cooling the barrel. Someone said they wrap their barrel in a wet towel to speed up cooling. Just a thought-but it worked for me.

ORIGINAL: Ridge Runner ditch the 777 and shoot regular pyro, try lubing your sabots with bore butter, and don't clean between shots. I won't shoot mine clean! also the tradions 250 gr. apb bullets shoot very well in my TC. RR |

But I do want the extended range; it isa a must. Shooting a 250 G S/W or Hornady SST both with a black sabot not the yellow one. Yesterday I went out to the range and shot at a target (3 777 pellets same projectile as above) and was able to hit in the 7 and 5 ring at 200 yds using the 2nd circle in the Nikon omega BDC so the scope seems to close with that load (for which it was designed for) Here in Iowa the shooting ranges can very from 50 yd’s to >150, since we have lots of timber and open fields and pastures. I need to find some lose 777 since no one sells it in my home town. Maybe I should just use a 200 G SW instead of 250… |
RE: TC Omega w/ NIKON BDC optic.
Here are 2 charts for loads I shoot in one of my guns as a comparison. The first one is of a 250 Shockwave over 130gr of Pyro pellets and is not that far off what the Nikon is set up for. The second one is a 200 Shockwave over 110gr of 777 2F that has a similar trajectory. Either one should put you close using the BDC scope.

RE: TC Omega w/ NIKON BDC optic.
And just for comparison, here is what I generate with my Omega w 300gr Nosler Partition PP HG, 110 T7 2f, Win 209 Primer. Very accurate at 100 and deer moa at 200 (6 inch groups). I'm sure the 200 yd groups can be improved with more practise.

RE: TC Omega w/ NIKON BDC optic.
HuntAway,
That is an impressive velocity for a 300gr bullet with 110gr of powder. It is not much under the speed I'm getting from 130gr of Pyro pellets and a 300gr SW (1945fps). I'm getting about 1850fps out of my 26" barrel with the same powder load and 300gr SW.I'm guessing the extra speed is due to the longer barrel your gun has over mine. |

The muzzle velocity is what I recorded at 10 paces from the muzzle over the chrony,at 100 yds over the chronyif I remember correctly they avg 1554 fps. So, the table is pretty close. I didn't have the nerve to shoot it over the chrony @ 200.:(So the table is close but not exact. I'm sure there aren't any moose, elk, bear or deer that would be able to tell the difference though.;):D |

And how did you come up with all that data? Do you have a ballistic calculator of something? |
