Strange to me anyway.
I've been shooting my VTR (.308) for the last few days. It's a new rifle and it's been through a decent break in process (posted elsewhere).
Today was "check loads" day so I set up at the 100 yard range. I loaded 4 groups of 6 at .010, .050, .090, and .130 off of the lands. The .090 group was better than the others. .130 was so bad that I didn't even shoot the last 3. With that noted I moved over to the 200 yard range and shot some "foulers" that I had also loaded.
The "foulers" were loaded with 42.2 grains of H-335. Sierra says that's 2,700 fps but I didn't take my chrony so with the short barrel on the VTR I doubt if I had that kind of velocity. The 150 gr Sierra ProHunters (#2130) were loaded .010 off of the lands.
I cleaned the barrel after doing the test shots so I started on the 200 yard range with a clean barrel. The first round was 3.75" low and 2.25" left
2,3,4, and 5 were dead on and 1/2" - 1" of each other
6 was dead center and 3-1/2" right
7 was 1.5" up and 2" left
All in all a very strange group (to me)
Obviously I like 4 of them
Couple of things to note:
My scope is high. My cheek does not rest on the stock like I'm used to. The stock is an HS Precision that is very similar to the Sendero SF II stock. Scope rings are medium height. The rail is a 20 moa tac rail. Scope is a Leupold Mark IV 4.5-14 x 40mm LR/T. After I get back from a deer hunt next week I'll change the scope to a Mark IV 6.5-20 x 50mm LR/T (the old scope is going to find a new home on an AR10 in .308) which is why the rings are a little high.
I find that it is not intuitive to shoot with the scope so high. I'm used to anchoring my cheek on the stock and then adjusting as needed to see through the scope. My cheek or any other part of my face does not touch the stock. Is this normal? I "sort of" think that the 3 fliers were shooter related but I am also wondering if the first one was because it was more or less a cold / clean barrel shot and the other two fliers were because I shot fairly quickly and the barrel was pretty warm by the time I got to them.
