Good afternoon Sniperhide friends. Well, I got quite an education this morning. The angle of my scope as it is mounted on the rifle and the cant of the rifle when sending a round make a Huge difference in lateral placement of the bullet. More than I had assumed.
I was set up well before dawn this am. Shooting my Gen 1 Vudoo in a MPA Competition Chassis. I was shooting off
www.TargetShooting.com Rests Model 2400 and Mini 9. I had a good level 3" wide Front Rider Plate mounted to the ARCA Type rail on the forend of the Chassis. Conditions were essentially calm. A breath of a breeze later. But not much. Quartering from the left.
The thing I see is that any movement out of plumb has a significant impact on the lateral placement of the shot. As I played with the rifle, intentionally canting it, I could see where the bullet was going to go. All, or at least the vast majority, of my Error to the Right in my earlier post was due to rifle cant and or the scope mounted off normal with a built in cant to the right. This is especially true for those of us who use the marks on the Reticle as the means of selecting the proper hold over for a particular distance. (I would assume this would affect Knob "Twisters" as well, but that is above my pay grade. And not the method I use.)
My 100 yard shots were right on the centerline. There may have been a breath of wind later when I shot 200 yards. But the thing I clearly see is my Scope MUST be mounted properly with the Vertical Crosshair dead on Vertical. And my rifle needs to be held so the Vertical Crosshair is truly vertical as I break the shot. I "knew" this was true. What I saw today was almost 'shocking' to this old engineer/surveyor. I "knew it". Today I saw it. And it is a BIG lesson for me. My gun has to be level. And the Longer the Shot, the more critical it will be. (The pink inside most circle on the three targets is 1" Diameter.)
Thanks for your thoughts and ideas. 4Certain
