i'm shooting a t-c omeaga. its ss 50 cal. i'm getting terrible groups at 50 and 100 yds. i'm using clean shot powder 100gr (2 pellets)50 cal 45- 300 xtp by hornady. i have shot about 35 rds through it. no consitence. i also shot some power belts and some shock wave 250. thanks guys.

I am not an Omega shooter, but I do shoot a T/C Black Diamond XR. Are you swabbing between shots? If your not, this might be a problem. Are the projectiles loading hard? Are you shooting off a nice clean oil free barrel? Are you a bore butter user? Do you lube the sabots because you're not supposed to? Do you seem to be getting good ignition off the Clean Shot pellets? (They must be old pellets to still be Clean Shot)

Normally the Thompson Center brand of projectiles shoot very good out of the T/C rifles. I can push the shockwaves as much as 120 grains and they still hold a great group.

I would personally switch to a loose powder, although a lot of people shoot pellets. My worry with the Clean Shot pellets are they might be old and not consistant anymore. I would get some Triple Se7en loose and shoot that.

Some other projectiles to try are the Buffalo Bullet 375 grain SSB sabots. They shoot fantastic out of all my rifles. I also shoot a 460 grain No Excuses Conical with excellent results. I only push them with 80 grains of Goex FFFg but that is plenty.

Good luck with your rifle...

Clean Shot has been out of business around three years now. Your powder has either aged to inconsistency or been introduced to moisture... which breaks down it's composition.

Buy a new jug of 777, Pyrodex, Goex, Black Mag-3 or American Pioneer FFF-only. A.P. is the new, longer-lasting version of your Clean Shot. Even the former Clean Shot owner remains as owner of A.P. Powder Co.

After another 35 shots, let us know how you make out. It wouldn't hurt to buy some T/C-packaged bullets also in 180, 200, 240, 250 or 300 grain.

Triple Se7en is right again...........................that CleanShot is pushing up daisies. And the pellets are worse than the loose powder was for consistency.

For those 300gr SSTs, try 80gr of loose 777 powder or the 3fg American Pioneer, 85gr of Goex, or 100gr of Pyro. The Black Mag powder will probably run between 80 to 90gr for that bullet as well.

If you still plan on sticking to pellets, then 2-50gr Pyro or 777 pellets will be the trick to use with those SSTs.

I agree with everything Triple Seven and Mark Whiz say with one exception. I have a stainless .50 Omega and any combination of 777 powder loose or pellets cause a crud ring in my rifle that is more trouble than I care to deal with. Even with my .25ACP conversion to use rifle primers the crud ring is still about 20% there. If you cannot find Black Mag3 (which is now my powder of choice for my Omega) I would try to find some American Pioneer Powder and I agree use fffg only not the ffg (too coarse). Next choice would be Pyrodex loose or pellets. I would try a 50gr. and a 30gr. pellet if you can get both sizes to give you an 80gr. charge. My rifle shoots that charge under a 295gr. or a 348gr. Powerbelt just fine. I shoot 300gr. Hornady bullets but switch the sabot to Harvester brand as the Hornady sabots are too thick for my rifle and too difficult to get down the barrel.

I have the same gun and it took me a little while to get my gun to shoot good also but after about 30-40 shots thru it, it shoots great now. I use 2 triple 7 pellets and a 245 grain powerbelt aero tip bullet. I shot 2 deer with it this past season and am very impressed with the gun. I did not get a complete pass thru on the deer but they both went down within 50-60 yards of where they were hit.
Good luck hope this helps.

I tried clean shot a few years ago when they were still in business and th eloose powder stunk for groups,and the pellets aren't any better. I shoot primarily black powder, but have shot Pyrodex. choose either Pyrodex or 777 and I bet your groups close in.

Don't give up the ship on the Hornady XTP's just yet.
My Omega shoots the 300GR XTP's, SST's really well and at several different loads.
Ensure that your barrel sparkling clean and dry to start.
If this gun is new, you need to clean all of the packing lube from the barrel. Use a bore solvent followed with alcohol and then dry.
You may need to spit patch/dry patch between shots. I also follow up with an alcohol then dry patch between shots.

Select a different powder (Black Mag'3, 777, or Pioneer).
If loose powder start at 80grains and work your way up and settle with what shoots the best. (Loose powder BTW, will live/last longer than the pellets will).

If pellets, start with two 50 Grain.

Let us know how you end up.

thanks guys i will try all the above starting with new powder.
