You are liable to get the bullet out of balance.....remember that things spinning at near 300000 rpm.

If you cut the tip off of a FMJ you are running a real risk of shedding the jacket and leaving it in the bore after the lead core exit's

You do realize you can buy real soft points for the same price as FMJs, right?

Quality SPs dont need to be loaded to 5.56 pressure. Match the bullet's envelope with your MV, BC, and distance required. |

In a TMJ handgun MAYBE, but in a FMJ rifle nah leaving the jacket in the bore is a serious risk and could be VERY bad. if you need cheap JSP's from FMJ's simply flip the 55 grain around so it flies back forward. and no im not joking, Elmer keith started this out in the depression and it was seriously effective. not as good as a top notch JHP but easily on par with mid range ones. both in terminal impact AND accuracy.

Loading them backwards is what you want.

I can appreciate & respect someone getting curious & experimental, and I can definitely respect the asking for input before experimenting 'too' much. That said, this particular experimentation might be (okay, "is") a bad and dangerous thing to attempt.

I really doubt cutting a small portion of the tip off will be "dangerous" or anything. I wouldn't be surprised if it just made the projectile rapidly rip itself apart the second it hit something though.

Why not just buy Hornady 55 gr sp and load them to 193 spec?
Those are very accurate bullets. |

Quoted:
Don't know if this has been discussed before but... I was thinking to increase the chance of expansion/fragmentation in a standard 5.56 55 grain FMJ, (Federal), I could use a Dremel to cut a very small amount of material off the tip of the spitzer bullet, exposing some lead. I can't really foresee any feeding problems this would cause; factory soft points, whether round nose or flat, feed just fine. Seems to me this might be an option to increase terminal performance with no cost and a little effort. Or did I smoke too much opium this morning? Thanks y'all. Remember FMJs are generally open on the bottom. You can get in trouble if you open the tip also, but it used to be done for hunting. There is some risk involved of the jacket coming off. |

Yea, I haven't done this so there's no need to freak out. Just curious about possibilities...I like to tinker.

I bet you use one of them horseless buggies to get to work, too.  OP, I suggest the hornady 55sp as well. But, if you do try to dremel your fmj's, please shoot them into ballistics gel and report back....if you can.  |

The more rounds modified & fired, the higher the probability of one of those rounds causing a problem. While the risk of any given round being 'dangerous' is minuscule, this is an AR forum; and the overall cumulative risk in an AR would be higher than if used in a break-open single-shot. |

You don't need to expose the lead to get better terminal performance. Just removing a small amount of the jacket right at the tip makes for an extremely unstable bullet which will yaw quickly upon impact.
You didn't hear me say that, and I have no actual experience to back that statement up. Accuracy? Why would you need an accurate bullet? Really, the best thing to do is buy a 55 grain JSP bullet. Or, just use unmodified 55 grain FMJ, it works pretty good.

You can lightly score the bullets, if only I had ballistic gel and a big backyard.

I would also score it in a spiral pattern starting on the tip. Light score would break the jacket, like scoring glass. While no noticeable or weak at amohphseic pressure, it becomes weak at 300,000 rpm and 3,000fps.
