Admittedly, I am new to rifles. I don't know how to shoot them accurately, so I met up with a friend that is a rifle guy for a little guidance.
Our position was only 100 yards out. I'm not ready for anything further out, and anything closer with a rifle is kinda dumb.
Rifle- Remington 770
Cartridge- Hornady "American Whitetail" 139gr 7mm-08.
My target is on the far right.

After a few rounds to get used to a new caliber, I decided to load the magazine and go for the target. My first four ran the bottom of the paper. One in the green tape holding the target and the other three along the bottom edge.
Once I got the feel of it, I managed to get the next four in the green. While not perfect by any means, I managed to get shots somewhere in the neighborhood of the center at 100 yards, having very little to no rifle experience.

What surprised me was the 770 was not the crap rifle that a lot of folks seemed to think it was. It's not pretty, it's not high end, but it did what it was supposed to do. I had none of the bolt or magazine issues that I had read about online. I had zero trouble with the rifle. The shortcomings were mine and not the fault of the rifle.
The bottom line is I can see where I can improve. The 7mm-08 cartridge is nice, without too much recoil. What's interesting is I got lightly knocked by the scope after about 20 rounds.....a reminder that I was getting ahead of myself and to take my time. A rifle is not like a shotgun or handgun and requires a lot more patience.
