Put it on the Omega. If it's a good scope, and from what I can see from it's performance so far it is, then why get rid of it. Put it on a weapon it could be of use on. Maybe that's the "pack rat" in me talking. I hardly ever get rid of anything according to the wife.

Semi, just think if you didn't have those two lower right FLYERS that would have been one hell of a group to be PROUD OF!!! GRIN

Well anyway buddy that's some good shooting. I know some guys that would like to shoot a group like that with their centerfire at 300 yds.

Ed, you're right. Those "flyers" ruined a perfectly good two-inch 300 yard group, which would be the "less than 1 MOA" group I normally expect at that range. I blame it on the bullet caster.

(Had those two at the lower right been up there with the other three I would have had to change my undies after viewing the target.)

Maybe Semi...

But more than likely I'll bet it would have taken awhile for your "inflated head" to get back down to a more normal size!!

Semi, just think, if you keep practicing at 300yds anything under 150yds would be a slam dunk for you.

Something else I forgot to mention guys.

The rifle was centering dead on the bull at 100 yards. But note that the group on the 200 yard target above is centered about three inches to the right of the bull. And the group on the 300 yard target is centered about six inches to the right of the bull.

I believe that's a result of the TC #9930 scope mount being a bit offset to the left of the center line of the bore. TC made them that way to provide clearance between the scope and hammer.

Please don't take this the wrong way.........

IMO I don't believe it had anything to do with the scope mount.
What I highly suspect is the wind moved those bullets. It doesn't take much wind, especially a right angle wind, to move that heavy slow bullet quite a distance.

Using my Strelok ballistic app, and not knowing the actual BC of your bullet, I started with .210. A 90° wind of 3mph can move that bullet 4" at 200yds. Using the same data at 300yds the bullet will move 8.6".

If I use a BC of .300 and using the same 3mph 90° wind, it indicates a 3" movement of the bullet at 200yds and a 6.3" movement at 300yds. Even using an almost following wind and a 3mph wind speed, at 200yds the bullet will move 2" and at 300yds the bullet will move just over 4".

I'm not claiming to be a long range professional but I've gained a lot of experience shooting to 400yds, and even more after shooting the Friendship match. Even the slightest wind will affect bullets beyond 100yds and the heavier slower bullets are affected more.

I guess that could be BA. My ballistic calculator gives the bullet a BC of .284. Although I did not detect any wind during that shoot, 3 mph is mighty light.

Using Strelok.....With a 100yd zero, using .284 for the BC and "0" wind, it indicates 10.81moa or 22.64" vertical adjustment required for 200yds.

For 300yds, it indicates a 23.24moa or 72.99" vertical adjustment. For 400yds, it indicates 37.29moa or 156.22" vertical adjustment.

If I put in a left to right (90°) wind and at 4mph, at 200yds it would require 1.93moa or 4.06" of horizontal adjustment.

Same wind and at 300yds, it would require 2.82moa or 8.86" of horizontal adjustment.
