Miha has some extras of this mold. If you're interested, you should NOT wait. His post on the cast boolit forum, the Closed Buys/Waiting for delivery/in shipment forum, he said to PM him from there,(cast boolit forum). I'm sure you could get ahold of him through his website;

Good looking boolits there Snuffy.

I know how you feel pouring through those MP's for sure.

I got into casting my own early last year using the Lee 6 bangers.

Then I jumped in on the tail end of one of the MP group buy;s just in time to get my first, in only about a month's time. After that I was hooked.

I have 4 of them now, the 258 for the 41, the 503 for the 44, and the 452-640 and 45-270 SAA for the 45, if you ain't got his 45-270 SAA version I gotta tell ya you need to get one. MAN-O-MAN, what nice bollits it does throw. :D

Snuffy, I don't know whether to thank you or to cuss at you. After seeing those pics and thinking about it a little while, I now have a serious need to get rid of my RCBS 44-225 SWC GC mold. If I can sell it, it will make 3 molds sold to raise most of the funds needed for the new one from Miha. Ordered the mold yesterday for a hunting load and for use in a (hopefully) new levergun some day in the not too distant future.

Taking stock of the molds I have and which ones I use (and want to keep) vs the ones I have but don't use. 2 Lyman molds for the .357mag sold today. May need to start looking at selling off some brass too.

I see you were running your temps a bit hotter than what I and a friend are pouring at. Of course the alloy will make that the deciding factor as well though. We're at this time using mostly either range lead or 1/3/96 or 2.5/2.5/95 Iso alloy. So far we have both found that right in the 725 - 735 degree area, depending on which caliber mold we're pouring, is the sweet spot for these alloys. We both have the same molds I listed above.

I am hopefully going to put some other 16-1, or similar together in the upcoming weeks to see if I can keep my noses from blowing off at the velocities were shooting. The alloys listed above do good, but we haven't been able to find any hogs to test expansion out on just yet. In soft sandy loam which is what I pack my recovery buckets with, they are showing excellent expansion but I get rings and half rings whee the noses separated form the bases. Not sure just how this will be on a decent sized boar hog of around 200# up close and personal. I would much rather have the full boolit shreading through as much as possible over leaving the nose shed int he shield.

Stick_Man,

Your in for a treat for sure. Just be sure to preheat before you start casting with that big chunk of brass. It makes all the difference in the world.

When I got mine, I did the usual soapy scrub out, followed up with a heat up to get everything dried off. Once I had everything good and warm I used a Q-tip and applied just a touch of the included oil to the top of the mold, and bottom of the sprue plate, then after inserting the pins I wanted to use, I took the Q-tip and swabbed it along all of the pins where they stuck out the sides, then pushed them through and did the other sides. Just enough that I could see there was a film on them while holding the mold where the light would shine on the light oil verses the dry pins. It don't take much.

Once up to temp those pins will slide through like they are on bearings. I also found that if I alternated front to back, then back to front pours I kept the pins up to temp a lot easier. Don't get frustrated with the penta pins, they simply need to be kept hot, period. If you have boolits that stick, just bump up your alloy temp a smidge, and reheat your mold on the hot plate a minute or two. Once you get there they will fall off like they were greased.

One last thing, you might want to pick up a cheap cookie sheet to use to drop these on. I have had some, which once I was in a good rhythm, were deforming the noses and some of the driving bands as they dropped due to still being a bit soft. The larger sheet will allow you to dump them in a larger area and roll them out of the way once they cool down a bit. Thus reducing any chance of denting the noses or driving bands. Trust me when I say, once you get it up to temp and are dumping those fine HP's out you sort of get lost in the process, and are simply just pouring and dumping. I emptied my 4-20 in a heartbeat, and was almost shocked when I raised the handle and only got a dribble. LOL

Good luck with yours you will enjoy it for sure.

Mike, I totally agree with everything you just said. This will be my third Mihec mold. I am looking forward to it. With my .402-160, all I ever cast is with the penta pins. Haven't tried the round hollow points with it yet. I find the round hollow points drop better with my .359640 though plus the penta pins look like they are just a touch undersized for the meplate. The round hollows drop from the mold without even needing to bump or tap the mold at all.

I find that 700-730* works very well with my brass molds. Warming the molds up on the melting pot while the lead is heating up does the trick to where I am getting keepers on the second pour and often on the first pour.

I clean the molds first, lube them same as you do, heat them up and cool them a few times, then start the magic. No smoking the cavities, no release agents, just run the cavities naked and am getting great results.

Here is a pic of some of the .402-160s with the penta hollow points.

The Castboolits forum has a lot of group buys of custom molds. I have about a dozen, and I would have to say Mihec molds are top quality. Mihec's hollowpoint molds or hollow based wadcutter molds work great and the pins can be reversed to make a flat point bullet.

The only drawback to the group buys on the Castboolits forum is that the mold makers who participate are backed up past six months in orders, unless they have some overrun molds in inventory.

If you are LEO, you might want to avoid the Politics and Religion forum on that site though...

Well, I just got my mold from Miha on Friday. It took 5 days from when I sent payment (via Paypal) to arrrive at my doorstep. Excellent! Looks fantastic. I couldn't wait to give it a try, so I quickly cleaned it up with some Dawn dish soap and hot water to remove any remaining cutting oil from the cavities, then followed that up with some brake cleaner/degreaser. I put some handles on it and promptly heated it up (resting it on the top of my casting pot while my lead heated up). Knowing these molds like to run hot, I let my alloy get up to 700 degrees before I poured my first. Started with one cavity, closest to the pivot point, for 2 pours, then added a cavity. Poured 2 more, then added a third. Then the 4th cavity and all was going well. I had each configuration set up, small round hollow point, large round hollow point, pentagon hollow point, and solid flat point. After 2 pours with all 4 cavities filled, this baby was producing works of art. Once again, Miha has lived up to his reputation. Other than cleaning remaining oils off of the mold, no further work was needed. The boolits fall off the pins as soon as the mold is opened. Even the penta pins do great. I am very pleased with the newest addition to my stable of molds.

Have any of you lucky son-of-a-guns with the pena HP been able to test these bullets with media? I've not seen the penta design until this post, and am very curious on how they would perform.

This is a 45 acp miha mold, I got it with penta HP and regular round HP.

Round HP on the left, penta on the right. Same in the next pic;

IMG_0382.jpg


These were cast from some real soft nearly pure lead with enough tin to get good fill-out. Harder lead resulted in much less expansion. But @ 45 acp velocities, that's not hard to understand.

These were cast of wheel weights, they expand, but not like the above softer boolits.

Someone did and posted pics. The pentas do not open as uniformly as the round ones, but they sure look good!

Well the expansion being what it is, has to be matched with alloy and velocity. Since most folks pour WW mixed with a bit of straight lead your still going to get a bit harder boolit than necessary due to some antimony possibly being in the mix.

In doing a BUNCH of research on what I might need to get my alloy to perform properly with some of these type boolits, I have come to the conclusion I am going to have to blend up something between a 16-1 and 25-1 lead/tin alloy.

There are plenty of pictures of different calibers in both the round and penta style HP's expanded quite nicely over on the Castboolits site. Since I am running loads which range form mid 900fps through a top end of 1350 for the 454, it will simply depend on how soft an alloy I can get by with before leading rears it's ugly head. I am hopeful however that by using something between the spread above that I can easily hit something which will hold together in my revolvers in a consistent manner. It sure would be nice to only have to blend up one alloy for them all, but I realize that with the differences in velocity, and the sizes of cavities this may not be the case.

As of now, I have been using some alloys which are around a 1/3/96, or 2.5/2.5/95, (tin/antimony/lead), and I have found it to simply be too brittle and while I get great expansion with some of the lower velocity rounds, anything higher than 1000fps will simply shed the noses in tiny pieces. While this may or may not be a bad thing when used for a hunting boolit, I would much rather have the noses rol back into a nice shroom shaped mass which should provide some excellent stopping power on both a deer or a hog.

In the coming couple of weeks, I will be blending up some alloys in the above mentioned range to see which one is going to give me something to work with. Hopefully I can get it done up and loads worked up before hunting season.
