When a round is chambered for firing, it should be fully sealed evenly all around. When the propellant ignites, the gasses push out in all directions, forcing the sides of the catridge hard up against the chamber - the rest of the gasses then propell the round up the barrel.
Bercause the chamber is the exact same size of the catridge the propelling gasses should not be able to exert more force in one particular area.
If there is uneven deformation of the fired round the causes are either 1) a damaged chamber or 2) build up of debris/oil/grease or 3) the round is not fully chambered. Oil or grease in the chamber will alter the chamber profile, so the gasses cannot expand the round evenly. Likewise, debris/oil/grease in the chamber locking mechanism may be enough to just prevent the chamber fully locking shut but still fire the round
There is an outside chance it is an ammuntion fault, but only a very small one for the previous reasons explained.
From my experience, it is most likely a hard deposite in the chamber, the area of the neck of the round, preventing the round being fully chambered. The part of the round not in contact with this dirt will not be in contact with the chamber wall and will be the part deforming, as it expands on firing.
Your first step should be to inspect the chamber and breech to look for obvious damage or dirt. Take the rifle to a gun smith for testing, he should have a machined gauge to test the tolerances inside the chamber. I wouldn't fire the rifle anymore until you have confirmation the chamber isn't damaged - you don't want the gasses of a fired round coming out of anywhere but the end the barrel!

One way to tell if it is a big-block car is if the car has a 'Power Blister' hood, which is a funnel shaped hood bulge on the hood .
The pull of the moon's gravity on the ocean causes the tides. When the moon is over water its pull causes the water to bulge (rise toward the moon) as the Earth rotates below the moon this bulge moves. Wherever the bulge is there's high tide. Everywhere else where the water has been pulled away from to make the bulge is low tide.
the German offensive at the battle of the bulge caused a 'bulge' in the allied front lines, thus came about the term 'battle of the bulge'........
Possibly, if your clothing is very loose and you find yourself sliding about on the saddle. Blisters are formed when the outer layer of skin is forced against the inner layer under sideways pressure and is then separated from it. The result is that the natural body fluid builds up under the skin and forms a bulge or blister. It is usually unwise to prick a blister as infection can get in. The advice is to leave it alone and eventually as the under skin heals the outer skin simply peels away.
Trying to lose weight! (The bulge is the abdominal or midriff bulge.)
There was a strange bulge in the lawn.The Battle of the Bulge is a historic event.Karen went to the doctor as soon as she noticed a bulge beneath one of her breasts.
One that comes to mind for me is The Battle of the Bulge. It was Germany's last bold offensive; then wanted to keep the allies from pushing onward into the Motherland. See the below link for more info on the Battle of the Bulge.
Hiatus hernia or hiatal hernia can cause this.Paraesophageal type hiatus hernia is the cause of a bulge in the right side below ribcage on my body.
It means when your in space and you have a big bulge.
The bulge was when the Germans surged ahead 60 feet in the Allied defenses in the Ardennes' Forest.
A normal anteverted uterus does not cause a bulge below your belly button. The entire normal uterus is so small that it is tucked behind your pubic bone. If you have an abnormally large uterus, then it may cause a bulging lower abdomen. Ask your surgeon for advice specific to your situation.
