Mushroom ends on SP cartridges

I was talking to a friend of mine who hunts deer with his Rem 700 BDL "Ducks Unlimited" rifle in 30-06 cal.

He showed me cartridges that had the soft points mushroomed that were in the magazine when he fired the gun.

He said the recoil of the gun was causing the soft points to spread out.

Has anyone ever seen this before?

Is there a fix for this problem besides using the gun as a single shot?

And, if you use a cartidge that has a mushroomed point, will it affect the accuracy?

Not sure where to ask this question.

Hope I've posted this thread in the correct forum.

It happens to me with my 700 in 30-06, and I think it is common with lead pointed soft points. In many years of hunting it doesn't seem to do much to hunting accuracy. I have ran a fingernail around a bullet to clean it up but not sure that is necessary and have shot some nice close to if not MOA groups with said bullets to see if it mattered, it didn't.
Some guys will buy bronze, plastic or other such bullet's to avoid this but again I don't think it is necessary for hunting applications at the ranges of 300 yards or less most of us shoot at.

Back in the 60's a Canadian company "CIL" made ammo with a plastic tip called DYNAPOINT to try to eliminate the deformation problem.It was agood idea but the bullets were too explosive for big game.

Another major bullet manufacture decided to try the same thing.....

NOSLER came out with the ballistic tip.They had the same problem as CIL, they seemed to have worked the bugs out now.(for the most part)

It really doesn't hurt anything, but if it really bothers you there are several things you can do about it.

Remington has long offered it's Bronze-Point hunting ammo.
Winchester addressed it with it's Silver-Tip line over 50 years ago.

And today, almost every ammo manufacture offers some form of plastic tipped hunting bullet.
Remington's is the AccuTip, Federal uses Nosler Ballistic-Tip bullets.

If you just have to stay with lead tipped bullets, your rifles magazine can have spacers silver-soldered in place that the cartridge shoulders butt up against under recoil.
That stops the bullet noses from hitting the front of the magazine.

They have long been used in very heavy recoiling rifles such as the African dangerous-game calibers.

It will not hurt anything. I can recall the old Rem. Model 30s (fef-
ined Model 1917 actions) owners would install strips down the inside
of the magazine box, I think forward of the case shoulder. It pre-
vent the back and forth movement that batter the tips on the forward
movement against the front of the box magazine:D
