Horizontal Stringing?

[Hardwoodmaterials]

I went out today with 2 M/L both CVA Optims V2's and we figured out a good load for one that shot just a hair over an inch at 100yds in a nice circular pattern. The other one which of course is MINE I couldn't find what it liked before I gave up for the day. I did notice that most of my groups were with in 1-1.5 inches vertically but would string out on both sides to about 3-4 inches. Of course some bullet/sabot combos did better than others but they all spread out side to side. I'm using BH209 powder and I tried 100gr and 110gr(which the gun hated with everything I tried). I also tried the Barnes Expanders w/MMP HPH12 sabots, Expanders w/Harvester smooth black sabots, Shockwaves w/ Harvester smooth black sabots. I have a few more combos to try but would like some input from anyone that might know what is causing the horizontal stringing.

Check your scope mounts...

I'm going to take the scope off and remount it just to make sure before I go shooting again.

Is this a new scope or have you used it before? Possible the scope has an issue.

99 percent of accuracy issues with m/l are bad scopes. They are bad on scopes or too much powder.

Letting the barrel cool for 10-15 min might solve your problem. Never thought of that till I started shooting smokeless.it works the same way no matter the powder

After completely removing the scope and mounts and reinstalling them and another trip to the range I have decided it has to be my brand new Vortex Diamondback scope. No matter what I try it will hold vertically within an in but spreads the shots horizontally about 4-5 inches or so. Its VERY aggravating to shoot 2 and have them touch then the third be 4 inches left/right or shoot 3 and they all spread out evenly across the paper all touching the same horizontal line on the target! I called Vortex and they said to send it in and put rush on it and they would have it fixed and shipped back to me in 2 days after they receive it.

I had similar problems with the knight sabots I tried. They were a very tight fit in the bore. I tried Barnes 250 gr, TE-Z, and it shoots great. The T-EZ sabots load much easier.
