    I know there will be those that jump my ship right off on this one but here goes anyway... I shoot a lot of 9mm and as everybody knows fmj is the cheapest to shoot and provides suitable accuracy. I do a fair amount of plinking and would like to shoot hollow points. Would it be hazardous to make a jig for the drill press and drill my own hollow points from fmj's? My thought is the low velocity in 9mm amo would prevent even the crappyest bullet from doing anything stupid in the barrel. During my plinking sessions I would prefer hp's but not at 2 to 4 times the price of fmj's. When I am not plinking the gun is loaded with Hornady Critical Defense loads at $21 for 25. My plinkers are either Blazzers or American Eagles at about $11 for 50. I remember reading about folks cutting a X in the nose of bullets with a knife to get better expansion and better bullet fragmentation during a ricochet. Thoughts?

    For safety I say don't do it. The mad scientist in me however...

    Low velocity 9mm?

    I would vote FAIL. It would be hard to keep things centered up and not screwing up the aerodynamics or balance, i would think. I also don't want to drill a loaded round, maybe you could try drilling some bullets and loading your own cartridges?

    If you know anything about reloading. You know there is a ballence between bullet weight and amount of powder. By drilling into your bullet you are removing weight from it while keeping the powder charge the same this could cause increased pressure in the chamber and could harm your weapon and possibly yourself. I have played with this before but I drilled out my bullets then weighed them and figured my powder and loaded my round. As someone said it is hard to drill in the center. I had better luck using a belt sander to just take off the tip making it a soft point.

    Yea...uh...no.

    You're talking about introducing heat, a likely source of ignition, to an explosive device. That's just damned stupid.


    Its not that it would be hard. Jig, drill press, center punch....

    Epic foolish thought.

    Mold your own lead bullets and reload.

    Just lookin for thoughts. Stupid, maybe, epic, nah. I can see the best advice is to add to the hobby and start reloading. I'm not going to argue for the original question, but heat, center punch, come on now really? I may be stupid but I am not damn stupid.

    Something that hasn't been mentioned:

    FMJ bullets are made by putting lead into a "cup" of jacketing material
    and forming, leaving the lead exposed at the base.

    Hollowpoints are formed in much the same way, but the base is covered
    and the exposed lead is at the tip.

    If you make a hollowpoint out of a FMJ, you end up with a tube of
    jacketing material surrounding a core with lead exposed at both
    ends.

    The tube (jacket) can stick in the bore, blowing the core out the muzzle.
    Next shot with the jacketing tube stuck in the bore? That's how
    people get nicknames like stubby.:eek:

    Moved it to reloading-

    Duck, as said, not a good idea for several reasons. Possibility of cartridge going bang (LAST step in reloading is seat and crimp bullet)

    Off center hollow equals off balanced bullet, equals accuracy of a thrown chair.

    As said, very good chance of obstructed bore from shooting core out of bullet. Next one behind that would be ugly.

    Now, I have to ask, why do you want to shoot homemade HP for practice?

    And not a slam- you asked honest question, and got honest answer. DO look into reloading.

    If you start reloading, Rainier or Berry's 115 grn copper plated hp will cost you about 10 cents each. Add primers and powder and you will be looking about 16 cents a round if you have brass. You can get a Lee loading set up for about $100. You will need some carbide dies and a taper crimp die. 9mm does not use a lot of powder. You will spend more money on reloading stuff as you progress but that can come slowly. I may be on the high side for components as I dont have big box sporting goods stores for my powder and primers. The hazmat fees will kill you on shipping primers and powder so I buy it local.

    Reloading sounds like a lot better idea then blowing your hand off or losing your eyesight.

    i agree with the others that trying to make a jhp out of a fmj bullet sounds like a recipe for disaster. like others have said, get into reloading, you can start out with a reloading kit from Lee for not much money, and buy jhp bullets in bulk, then you will have a decent hp round to practice with.

    if thinking about doing the reloading thing, first items to buy before you ever buy any equipment, are some reference books on reloading in general, and read them several times. reloading can be safe and rewarding if done safely and following proper procedures. if not, it can be very dangerous and could put yourself and others at risk. follow the procedures and don't try something unless it's proven.

    I agree with Bill here.... But they do make kits to do it, I only found it for the .22 and 7.62x25....

    Don't do it!

    1. You gain nothing but increased liability.
    2. 100% guarantee to hurt accuracy.
    3. A complete waste of time.
    4. You loose fingers, eyes and gun parts.
     
  17. Why? Seriously.

    In short, like everyone else said, it's a lot of work for no real gain or advantage.

    Forster used to make a 'hollow pointer' jig and attachment for doing this very procedure. (Maybe they still do; I dunno.) The Forster device was for lead bullets only, as I recall.

    One could fix up a rig and perform the action without harming anything. Possibly it could be done without totally screwing up the axial balance of the bullet. Probably accuracy would suffer. But to what goal? The construction of the bullet won't allow it to expand. The old practice of cutting an X in the nose of the bullet had mixed results. IF one cut deeply enough, the bullet would fragment and create a more serious wound. This practice was for the express purpose of killing the subject of the impending shooting. If it were used as a self-defense measure, it is pointless, because it doesn't particularly cause a quicker incapacitation.

    Depending on how far back you removed the meplat section, you might end up sticking jackets in the bore. Empty jackets like this are not known for blowing up a firearm, but they do cause ring bulges in the barrel; not recommended for best accuracy.

    Sorry to contradict CFRAGA1978, but removing weight from the bullet will not raise pressures. Lower bullet weight and all other factors the same will lower chamber pressure. In an extreme case, it could lower pressure enough to stick in the bore. More than likely, the lower bullet weight would fire normally. Point of impact will change to some degree.

    Just for the record, I do load for 9x19 NATO. All I load is NATO ball equivalent, and only for practice. I have some scrounged commercial ammo for serious carry - and I don't carry 9x19 NATO as a primary weapon very often.

    I think by now you should have seen enough information that suggests you should not try this. If you want to make HP ammo you should get into reloading and do it right.

    Youd be lucky if one didnt go off while trying to drill them, all around bad idea. All it would take is the bit getting lodged causing the round to turn the same speed as the drill bit and grinding the primer on the table....boom
