I am doing our ammo test, and shooting a Ruger 10/22 with a Varquharson barrel.

This rifle has had an enormous amount of ammo through it, and I have never experienced teh following.

With 2 ammo types, shooting groups at 100 yards. I got one bullet out of a group to hit the target sideways!!??

This only occured once with each of these two ammo.

Anyone can hazard a guess on why this happens?

There is a definite chnage in teh sound of some rounds, but none has hit the target sideways before.

You say it only occurred twice but my guess is that it is happening more than you realize. When a bullet hits paper sideways, or nearly sideways, it leaves a very discernible hole. But many of your bullets could be wobbling to lesser degrees and still hit the paper close enough to straight on that they leave a hole that only appears normal at a glance.

Shoot into the white and then push the edges of the holes back together from the back of the target. You will see the grey rings created by the bullets as they punched the holes. When you do this, do all the grey rings look like perfect circles or are some of them oblong or oval?

My guess is that the throat of the barrel is highly eroded. Perhaps the rifling at the muzzle is going as well.

What kind of ammo were you shooting?

I shot in matches with my Suhl 150-1 and its factory 1:19" twist barrel last year and when temperatures were below 50 degrees F, sometimes half (or more) of the bullet holes on target would show varying degrees of wobble- from a little to a lot. I was shooting Eley Match. Too slow of a twist rate to stabilize bullets in lower temperatures. That is the only time I have seen anything like it.

I don't think this is a problem with the rifle.

Because just for this test, I have shot almost 3000 rounds through it, using 55 different types of ammo, including the ones I got these results from.


I have one in front of me right now, it is called POBJEDA GORAZDE TARGET 22LR. It is made in Bosnia and Herzegovina, and described as a standard velocity competition cartridge!!??

I'd bet it is a matter of inconsistency - either in powder load (dud load) or bullet lead material (inadequate rifling, or partial lead fragmentacion or subsidence on rifling area occured)...

On the lighter side - especially since ammo stamped with "competition" label - with bullet landing sideways one has twice the chance to hit the bullseye

Have you cleaned it lately.

Might have been real low vel caused buy lower then normal powder charge.

Enormous amount of ammo and "3000 rounds just for this test". Have you examined the throat and bore of the rifle?

3000 round of 22rf heck I have a 10-22 that has 50000 rounds through it 22 MK1 ruger pistol more then that.

I have shot 500 in a few hours with them

22rf barrels most likely go 100000 plus with out trouble.

This particular rifle must have had at least 100,000 rounds through it.

It is a very old rifle my father had, and when he passed away, I changed teh stock and barrel - and gave it to my daughter.

It is always here in our shooting range, and teh kids love to shoot cans and gold balls with it.

I have 10 spare magazines for it. And the kids have shot over 1000 rounds through it in one day.

I give them cans of Lapua Club ammo that comes in 500 metal cans.

But, I still believe this has nothing to do with the rifle at all, but a shortcoming of the ammo.

I will post all teh results next month.

It would be easy to belive that a load was short some powder.

It could be that some of the bullets in that ammo are undersize, and not being stabilized by the rifling.

Also powder charges might be too light in some cartridges.

I would weigh several rounds on a good scale and compare the differences per round to a known good 22LR ammo.

I would also take a good look at the bullets with a magnifying glass.

Are the crimps consistent, bullets look the same, etc.

This is a reach but I had a similar problem with a brick of Remington standard velocity target ammo. Ended up calling Remington and they admitted some got away from the factory with little or no lube. With these the more you shot the worse it got. These left noticeable leading in the barrel.
C.G.B.

Yesterday a friend and his son came over to shoot.

They shot BR50, at 50 yards, using the Bleiker match rifle, and Eley Tenex ammo as you can see in above target.

I then told them about this, and the father was not very convinced.

So I gave them this ammo POBJEDA TARGET and asked them to try shooting it.

The results as you can see above.

Some bullets went in sideways.

So this is definitely an ammo problem.

Some bullets were actually hitting the target about a foot below where others were at 100 yards.

Wow... have you tried pulling bullets to check the powder charges or priming? Sounds like they may have let a bad lot of ammo out the door.

I brought some Aqulia 22rf for a great price fresh brand new. After I had 50% miss fires the price wasn't that great.

We have 3 different types of ammo marketted by a compnay called SK, and made in Germany.

It has a rabbit drawn on the underside of the box.

One of these is so bad I stopped shooting it at 100 yards. The target look like it has been shot with a shotgun. Some shots were hitting the target about a foot bellow others, missing the target altogether.

Have you shot many over a chronograph yet?

Either they are not spinning fast enough to stabilize or they are too small in diameter, it cannot really be anything else.

If you look at the ones that have been shot, especially the ones that might have tumbled (sometimes the nose has a little sideways bend to them) you can inspect the rifling marks. If the marks are present I would suspect low velocity and if rifling marks are absent I would suspect undersize bullets. About the only other item I can think of would be to pull a bullet or two and compare the length to a different bullet. I suppose it would be possible for a 22 bullet to be too long for the powder charge and become unstable, though I rather doubt this happening but it could be a possibility I suppose.

OK Saeed, I know you have some dough but honestly that is just flaunting your wealth.


Sorry a guy that can only speak one language shouldn't tease a guy for a mistake in a language that isn't his first.

Back to your question. Since you said some rounds sounded different I think that's your problem.

He must have got them from the movie set of
Gold Member!

I bet that some of these bad rounds have a severe cut on the base, or are severely undersized.One way to check the condition of bullets is to shoot them into a snowbank, where they can be retrieved without distortion.....oh, that won't work for Saeed.....try water in 5 gal buckets.
