Thats a little more like it. Don't know what happened on #2.
My Omega shoots the 240 XTP/Mags better than any other bullet I've tried thus far (granted... thats only been five). I shoot 80gr of Blackhorn 209 powder... its a nailer. Haven't had the thing much more than a full week and have already whacked a pair of deer with it.

thom2's Omega Group getting closer
Attached is a target I shot this afternoon using the Hornady 250 gr SST and 100gr of T7. 110 gr of T7 wouldn't group at all.
I can't understand why two shots are high and two are low.
I swabbed the barrel the same way after each shot.
2-split patch (H2O)
1-dry patch
I think I'll weigh the powder for the next round. I believe the volume 100 gr of T7 weighs about 70 grains.

I have one last idea
remove the scope and shoot it with iron sights.
I had a centerfire rifle that I know groups 3 shots inside a dime at the 100 yd target.
well all I started with 2 shot the same place next shot 6" high
next low
the scope was on it way out

I think the grouping problem maybe relative to the cheap Simmons Whitetail scope I put on the Omega. Tomorrow I'm replacing it with one of my high end Leupold's off of a .270 rifle I seldom use . ——— Stay tuned.
I've helped a lot of guys in my club figure out grouping problems. It's seldom a scope problem - loose mounts sometimes - but almost never the scope.

The first thing I did was check the mount. It seems tight.
But I screwed up big time last Saturday helping a buddy figure out grouping problems with his Knight MK-85 using T7 and Powerbelts. We put about twenty bullets down range with various loads before we realized that the front scope base was loose.
After fixing that we were still having problems, though to a lesser extent. He was sure the scope was faulty. But after convincing him to try dropping the powder charge (he didn't want to go below 90 grains) we hit the magic load with 70 grains. I don't fault you for trying the Leupold "just in case" - that's what I'd do too. I hope the scope is the source of the problem, but still bet it's not.

Keep me posted on the scope change
I like to add to center the scope take it at low power and like the in the bathroom vanity glass place it up to the glass (front part) and look into the scope then turn the adjustment screws until you see the cross hair in the middle ;now the scope in dead center in the tube
