    A while back I bought a hollowpointer/accurizer tool. There were doubts expressed as to whether the modified bullets would perform.

    I ran a 100 yard test. However, before we get to that test, let me walk you through the process of making the ammo.

    [​IMG]
    Here are the components to the hollowpointer...

    Fairly simple setup, but precise.

    [​IMG]
    The first step is to put the round in the bottom block.

    [​IMG]
    Assemble, and put on some sort of press - even a hammer will work.

    [​IMG]
    Pull the handle...

    [​IMG]
    ... and a gaping hollowpoint (depending on depth settings) results.

    But how do they perform?

    They do shoot more accurately than unmodified ammo, but to the same point of aim. This is probably because they've been set to a standard size, and because the center of mass is further back. This is speculation however. I just know it works!

    I set up four water jugs at 100 yards, and fired into them.

    These are the results:

    [​IMG]
    This is the first jug. It's pretty well shredded.

    [​IMG]
    A line of all four jugs...

    [​IMG]
    Here's a bullet I recovered from right beyond the fourth jug...

    [​IMG]
    Two more stopped inside the fourth jug.

    I believe the variation in penetration is due to the fact that I fired 10 rounds, and kept firing after the jugs were pretty well empty. I tried this test before with three jugs and failed to recover any. I therefore added a fourth jug and kept firing until empty to try to get a few decent samples.

    [​IMG]
    This is a picture of the unmodified round, modified round, and the three bullets I was able to recover.

    Keep in mind that this is CCI 40gn LRN I modified. Their website lists the velocities thus:

    Muzzle 1235

    50 yards 1092

    75 yards 1040

    100 yards 998

    So, when the bullet impacted, it was acting as a heavy .22 short. Yet, it still expanded to over .36".

    These are doing better than my old standby, Winchester Xpert, and are of course more consistent.

    I'm impressed.

    Where did you get the tool? Interesting.

    I'm impressed too. Where is set up available from? Those look like nice little mushrooms.

    There is a fellow over on Rimfire Central that makes them. I think they're about $75.00 a set. Look in the classified section, he has a WTS thread.

    Paco Kelly over on Lever Guns also sells a similar tool.

    Hello,

    Yep, this one was made by D Rock at RFC.

    Paco's are made from brass and don't sound quite as durable. Could be wrong as I've never used his, but I'd much rather use tool steel.

    do the modified slugs group tighter as compared to un-modded?

    Hello,

    Yes, they do. They're all resized to a constant .224" diameter.

    I don't think I'd do the upsetting with a hammer. Where is the pressure going to go if you touch off a sensitive primer? For that matter I don't think I'd try it in a press either, but that's just me. My .22 does what I want it to without modification.

    For comparison's sake, how did unmodified hollow points perform?

    Is there not a chance the bullet will actually be seated deeper--possibly causing overpressure issues?

    A 22LR bullet is a heeled bullet in that it has a step around the bullet that the case mouth rests on.

    One would have to 'strip' this step, or heel off of the bullet in order for the bullet to be set any deeper into the case.

    See what I mean...?

    As for the hammer thing...I would not!

    how about posting specs on your rifle and the price of the kit and link to?

    Then there's something fishy about the original post Uncle Mike. Those fired bullets do not looked like "heeled" bullets to me. Or am I missing something???

    As far as I know, all .22LR used heeled bullets, unless it's a shotshell.

    [​IMG]

    The rifle is a Savage Mk II BTVS in left hand configuration chambered for the .22LR. The 'scope is a Mueller APV 6.5 to 14 with AO and my first bipod ever.

    The sizer/hollowpointer can be had from D Rock on Rimfirecentral.com . I'd give you a more specific link, but I cannot get the site to run correctly for me right now. It's lagging.

    He does have it advertised in the "for sale" section.

    ASCTLC,
    The step on the .22 heel is not as pronounced as it appears in Mikes picture.
    It's only the thickness of the case.
    The base of a .22 is also slightly concave (similar to a Minie Ball) & when fired, the base of the bullet tends to obturate (upsets & expands to fill the bore) under pressure (approx. 22,000 psi).
    See the 8th pic in the OP.

    D Rock's thread on it is at:

    http://www.rimfirecentral.com/forums/showthread.php?t=231911

    He has a link to it in his sig.

    I also have one of these tools I use with a half-ton arbor press. Additional collars can be picked up at McMaster-Carr, part #6438K18. Works great so far. I should post some corroborating evidence if I get the time to go out to the range this weekend.

    Mr Smith,

    Are you shooting out a window?

    :)

    Just curious,

    I'd guess a sliding door into the back yard. If so, that's a nice setup...

    That's how we used to harvest our spring and fall deer each year at my ex-mother-in-laws place in Bandera :)

    That is some pretty amazing expansion for a .22lr... I am impressed.

    Yes, I'm shooting out the door. It overlooks my 100 yard range, and prime squirrel habitat :D

    I am not trying to be a smart-A, but couldn't you just buy hollowpoint bullets? What is the benefit over a OTC hollow-point that is 36 grain? Is it the extra 4 grain weight?
