Hey guys!

I am having a hell of a time getting my Kar98 sighted in. There is no rhyme or reason to it. Rounds go high then go low when aiming at the same spot!

Now before the usual it's you, not the rifle thing starts, other people have tried this rifle and have had the same issue.

Could the barrel be worn out? There is some minor pitting in the barrel but the grooves seem deep and fine. I am using Privi 8mm Mauser ammo with 190 grains. I know the WW2 German ammo was more like 170 grains. Could the ammo be too hot for the rifle?

I expected a lot more out of this rifle when I bought it so I eagerly await any advice. Thanx!
 
How big are the groups? What range are you firing at? It could be possible that there is damage or wear to the barrel. Maybe something is loose like the sights, action screws, etc?
 
had the same problem with my yugo. at 100 meters it was a shotgun at 200 shooting yugo surplus i was getting 3-4 inch groups off of a rest. the surplus is 198 grains i think.
 
What condition is the stock in? Many milsurps suffer now from dried out stocks and wood shrinkage. This destroys any bedding the rifle had which will cause erratic groupings.
 
Also the bands could be pulling on the barrel. Is the rifle all original or RC or what? Theres a good writeup on gunboards about accurizing mismatched K98s.
 
Thanx for the suggestions guys!

All I can say is I was trying both at 50 and 100 yards. I tried compensating for the battle sight but it made no difference. I cannot even talk about groupings. Half the time I was hitting the top of the sand berm behind the 50 or hitting the very bottom of a 11X14 target.

Nothing seems too loose or too tight. Any youtube videoes you can suggest to check things like the action screws?

The wood on this rifle is very good and non bubba'd. It is some sort of capture as the stamps have been scratched out but I was told from the seller that is was not RC. I believe the only thing not original on the rifle is the magazine.

Thanx again!
 
If the bore isn't too pitted and the rifling is relatively sharp then there are a few things to consider.

The ones mentioned thus far are pretty relevant, sometimes the action/receiver isn't a good fit for its current stock and this will cause wild unexplainable innacuracies.
Another that was not mentioned could be the crown! Check the very tip of the bore, is it beat up? Uneven, rough surfaces around the outer edge? If the muzzle crown is badly damaged this will affect your accuracy drastically.

Another that was mentioned is the stock being warped. The issue with this is that if the stock area that the length of the barrel fits in has warped with time and age, it may be putting uneven pressure in different areas along the barrel causes the barrel harmonics to be right out of it when firing. This is the case with many mosin nagant milsurps.

The best way to check this would be to put the rifle together without the barrel bands, upper handgaurd or front metal piece. Take a 5 dollar bill and slide it all along the length of the barrel. It should slide without catching all the way from tthe tip of the stock to the receiver of the action.

If it is catching all over or in certain spots, you may have to lightly sand the interior of the stock channel in those spots to take the unwanted pressure off the barrel length. This would be "altering" the rifle but not in any major way or way that would be noticeable.

Some people will sand out the inner barrel channel of their mislurps and then use cork shims at equal lengths along the barrel. It's a bit of a trial and error game.

Also try shooting it at 100-200 meters and further. You may find the rifle shoots well at further distances although it's unlikely if it is right out of it at 50-100 meters it will be exponentialy worse the further you go.
 
Have you tried flat-based hunting bullets, or the S bullet (if you can find it), or cast bullets, all or some of which can do better than the sS bullet with its short bearing surface.
