    Looking for a multi-cavity, .452 HP bullet mold in the 220-260 grain range that allows for a gas check.

    Anyone know where I might find such a creature ?

    Neither google, nor bing, is providing much help.


    Thanks in advance !

    No, can't think of any.

    The problem is, a HP mold requires a removable plug that forms the HP cavity.

    Trying to use multiples of them in a gang mold would likely slow down casting enough to let the mold get to cold between pours.

    Yea, RC, your right, I didn't read the post close enough. The link I put on my reply only deals with singles.

    Sorry Blarby

    I'm loosing my mind, I mean they don't have gas checks.

    You'd think this would be easier to find.

    HP mold ? No problem.

    Multi-cavity HP mold- no problem.

    Gas-Check - all of the above no problem.

    Its putting them together that seems to be the problem.

    blarby,

    I'm just questioning why you feel you need a gas checked .45 Colt bullet in the first place? I've got the mp-mold 270gr HP bullet mould (casts at 265gr with my alloy), and I drive them at 1050fps out of my S&W 25-5, and they go clean through whitetails. Gas checks are just an unnecessary added expense for the .45 Colt. Hope that helps.

    What if the goal was using softer lead, so they WOULDN'T go right through something as thick as a deer?

    Thats kinda where we're going, ya :)

    Clean through is great on a lot of things- we're looking for near 100% energy dump.

    Heck- at this point i'd even take a single cavity GC HP mold in the 200-260 gr weight range for .452.

    Then you simply use softer lead and less powder. 8.5gr of Unique just about duplicates the original power of the old .45 Colt. In any case, my point was, there is simply no need for gas checks on the .45 Colt.

    Unless, in this case, you are looking to use maximum velocity and a soft lead bullet- without the accompanied loss of accuracy and leading that comes from driving full power soft lead.

    Essentially, the goal here ( unless I am missing something, JS- feel free to chime in... I am but a simple set of hands to work the will of your brain child !) is to create jacketed level performance and expansion for half or less the cost of using jacketed bullets.

    What revolver will you be using, and how fast do you want to drive those bullets?

    *looks at John*

    I think it was somewhere between "As fast as possible" and "slower than impossible".

    I cant say for certain, but I believe the intent was somewhere north of 1,300.

    For the exact loading data, I defer you to the owner of the revolver !

    I have an RCBS mold that cast a 270 gr SWC that I had converted to a hp by Ken Ohlen. It now casts a 255 gr hp and casting them is a breeze. The conversion included a spare pin set to turn it back to a 270 SWC. Pricey,yes but it's better than waiting on the gentleman from mp molds. As I understand it takes a while for him to make the mold then shipping eats up more time as he doesn't use UPS and the like. I'd post pictures but trying to set up an account to do so is a PITA and not worth the hassle to me.

    With the correct alloy, you don't need a hollow point or gas checks in 45 Colt to punch nearly clean through a deer and still dump enough energy to make a clean kill with no tracking. Nearly 1/2 an inch to start with, any expansion is going to make one (or two) big holes in a whitetail.

    *wants recipe for antimatter alloy*

    I really would like to see pictures of that custom mold ! Sadly, even though he could modify in pins, I don't think e could modify in rings to make the GC.

    I do however, have in my possession a 300 gr GC 6 cavity bullet mold... I wonder if he could work some voodoo on that one ?

    How much did it cost, and do you have that contact info handy ? ( If his email response is any indicator of the truth to which you speak, I mailed MP guy about 3 days ago...no response)

    What do you need an "account" for ?

    The goal is NOT, NOT, NOT to "punch through" a deer-sized living object. (Incidentally it would be impossible to both have 100% dump AND exit fully.) blarby has most of my intent, but I want a Model 25-safe lead bullet load that

    >weighs more than the commonly available 200 grain JHPs
    >weighs less than 260 grains

    A soft lead 220-240 HP would be ideal. It should be fired faster than 800 fps, but should be slow enough that recoil is controllable, and that it won't destroy a SAA-strength revolver if someone fired it in one.

    I HAVE a hunting revolver that will blow .452 bullets through an entire herd of deer, so please forget deer in this discussion. I want a defensive load that won't be horribly overpenetrative, has controllable recoil in a 4" N frame, and that is economical enough that I can fire a couple of cylinders of my defensive loads every time I go to the range, without spending $1.00 every time I pull the trigger.

    John

    Not true for all. You want a Cramer style or one of NOE's RG series molds. Both of these allow for very quick casting.

    Here is a pic of a Cramer style mold.

    Au contraire. The goal is to have a large entrance and exit hole in whatever the living object is, to both promote the loss of blood resulting in the cutting off of oxygen to the brain, as well as to create an easy to follow blood trail. Unlike highpower rifle cartridges which can rely on hydrostatic shock as a contributing factor to lethality, most handgun cartridges rely on bullet diameter, weight, penetration, and bullet construction to impart lethality. A handgun bullet that has completely penetrated an living object has actually done more damage than a handgun bullet that has only halfway penetrated with a "theoretical" 100% energy dump.

    I 100% assure you that I am not looking for a hunting bullet. I don't want a "blood trail" if I fire defensively, I want the attacker to stop attacking, and I don't want to pose a hazard to any innocents in the vicinity by overpenetrating. This is my goal, and I do happen to understand my goal fully.

    dragon813gt, that's a really neat looking mold.

    I've got 3 of those mp-molds (.45LC, .45ACP, and .357) like above, and I can tell you they are easy to cast with and the workmanship is outstanding.

    My RCBS blocks are very similar in design to the mp blocks that are pictured

    That cramer style is a pretty slick mold.

    That style is pretty much what I had in mind.

    I like that its got a set of round HP tips, and a set thats designed to begin pedaling on impact.

    Now- if we could just find one that meets JS's needs......

    It casts solids by reversing the pins as well ;)

    Did you check Accurate molds? I don't think he makes hollowpoint molds. But there are others that will covert one for you. Erik at HollowPointMolds is one that can modify a mold to a Cramer style as long as there is enough metal beyond the nose. He can also convert some to his inset bar conversion which is really slick.

    Unless there happens to be a group buy on cast boolits for what you want. It looks like it's going to have to go to two different people because of the hollow point.
