I just bought a new TC SS 50cal Omega. It is topped with a Leupold VX1 3x9. I'm using 777, Winchester 777 primers, and I'm trying to find a 250-300gr bullet that will yield a good group. I have some Shockwaves and XTP's and some SSTs. I will likely start with 100gr and move up and or down from there.

That brings me to my first question. My powder measure only moves in 10gr clicks do you think I will need to move in 5gr increments?

What are the 3 shot group sizes at 100yd that I should expect or try to achieve before saying that as good as it is going to get from this gun(2 inches, 3, more)?

Should I have a "clean" or wiped down barrel before every shot since my gun will likely be clean on opening day ready for the first shot?

How does your Omega shoot at 100yds and with what load (primer,load,bullet)?

Help appreciated,
Wally

I get 1 1/2 groups at 100 yards with my encore. 90 grains loose 777 and 245 grain barnes spitfire. Clean between each shot.

I would first try your loads with your 10 grain increment measure. I shoot 110 grains of 777 and a 245 grain Barnes Spitfire and get MOA at 100 yds. Last year I tried Winchester 777 primers had several hang fires. I would pull the trigger and nothing. 2 seconds later.....BOOM!!! Be careful with those primers. I use the Remington Kleanbore primers. When sighting in at the range I would clean after every shot to make sure you know where your gun shoots with a clean barrel since that's what you will be shooting opening morning. Once you get the group dialed in with your specific powder charge, then shoot a second and third shot with a dirty barrel to see how it groups.

I'm with DA, I don't clean my encore between shots because I don't want to have to clean it in the field. My gun is sighted in after firing a shot and the next 4 or 5 are dead on. I'm shooting 3 777 pellots and 275 arrowtips with kleanbore primers. I'm setup for a long range shots due to where I hunt, that's why I use 150 gns.

Are you using powder(FFG or FFFG) or pellets? Also, what are your trajectories at 50, 100, 150 and 200 yards with that load??


I use one 50 grain pellet and two 30 grain pellets. It's dead on at 100 yds. I haven't shot it at 50, 150, or 200 yet. I dropped a doe at 40 yds last year and it hit exactly where I was aiming if that helps any.

Well, I should have stated I'm using loose 777. I really like that info you guys are providing. I should be able to do some testing this coming weekend, I'll post the results.

Thanks,
Wally

trap,

I got out this afternoon, here is what I got so far.

started with 3 - 30gr pyrodex pellets, 250 gr T/C lead h/p sabot,
50 yds.

First two shot group(clean gun) 2.5" to the left,1/2" high,3/4"group.

Made adjustment to scope.

Third shot, 2.5" high at 50yds

Ran patch down barrel, not so bad.

Moved target out to 75 yds.

Forth and Fifth shots - 2" high, 1"group.

Stopped shooting, will clean gun and test fire more tomorrow. I want to know where it hits out of a clean first shot barrel before anymore adjustments.

Will post results tomorrow night.

trap,

Last night I stayed with the 90gr of pyrodex, but switched bullets, changed to T/C shockwave 240 gr.(spire point) to see how they grouped. Not to bad.

At 75yds the group is @1.5" after five shots.

I after 5 rounds down the tube, the bullets don't seem to set as well. I stopped for this session.

Cleaned and ready for tonights sitting.

I will post results later.
