tkcomer, if you are using the milspec sights that came on the rifle, you ought to know that the rear sights are not windage adjustable, so then you have to use the front sights to drift left or right as needed.
The Rule: The rear sight, if adjustable for windage, needs to be moved in the direction that you want the bullet to go.
The front sight, to adjust for windage, needs to be moved in the opposite direction that you want the bullet to go.
Now that you have that indelibly etched in your mind, use a brass punch to drift that front sight in the correct direction. A little at a time.
Good luck with your reloads.

That's what I was afraid of. The front sight is already drifted hard to the left. If I drift it much more, I'm afraid it will fall out.

Move the front sight to the right as 243winxb mentioned.
Set behind the rifle and visualize the front sight being moved and what the effect will be in relation to the groups that you have fired. If the sight is already shifted to the left, then that explains the group hitting to the right. Think about it.
That's a nice old Mauser that you have.

Oh crap, I had it backwards. Again. Thanks.
I'd really, reeally suggest that before you play with the sights much, you try a load that you know will be "accurate". so you can produce decent groups. I've had good luck with Turk and Yugo surplus ammo; the Turk stuff pushes a 154-grain bullet at around 2900 FPS and I can get 4-inch groups shooting offhand at 100 yards. A 180-grain bullet at around 2400 FPS produced 10 and 12-inch groups; I haven't worked up faster loads yet but the other posts are correct in that you should try pushingyour loads faster, if possible, to help stabilize them. 2900 FPS is AWFULLY fast for cast bullets but with the eight hardness, lube and maybe a gas check it can be done.
Once you find something you know will produce good groups, THEN it's time to mess with the sights.
