This is basically an inquiry of what MP molds you are using to hunt with. What's your alloy and whether you air cooled or water dropped them. How effective were they? Do you see any way to improve on the HP design? Thanks.................

I have several of the MP molds & have cast slugs in solids, Penta HP's, & deep HP's. I also powder coat them. I haven't had a good opportunity to get a lot of critter results,,, but in water jugs,,, I'm partial to the HP's for deer & solids for bear.

I use the deep hp's on all of mine. Don't have anything around here that really needs a 300 or bigger solid.
Per talks with sixshot I settled on a 70\30 ww\pure alloy air cooled and they seemed to work fine.
Since then I started PCing them and use water dropped ww.

I think the answers will be all over the place on this one for a while because Powder Coating is still quite new & most of the reported kills have been with the 385 gr HP in 475/480's & that big bullet can simply over power about any animal out there.
When we start getting more reports from guys shooting 41's, 44's & 45's I think we'll have some solid data to work with. Remember a PC bullet is going to end up 10-11 BHN so you probably won't want a HP on a lot of animals bigger than deer, we'll see.
I'm not a huge fan of the Penta HP's because in very limited testing the "petals" tend to shatter. Having said that I did kill a nice 4x4 Muley buck 2 years ago with one that exited on a broadside shot. I think the reason it did was the shot was 94 yds & the load had slowed a bit. It was 10 hrs of Unique & the Miha 250 gr Penta from my 10 1/2" 44 Bisley.

Dick,
I did a post on your bullet and load over on Handgun Hunter; if you know how to post it here.

Kim, read your post, very nice kill with the round HP's I sent you. The buck I shot was hit through both lungs with one of the Penta HP's, I think you got much better results with the placement you chose. I'll see if I can copy & paste your post over here. Good job on that big doe.

Well, I just stumbled across this thread. I guess I'll sell all my .45 moulds except the Miha 45-270, which I use to cast hunting bullets, an RCBS 45-255 whose bullets just shoot lights out, and a recently acquired RCBS 45-250 RNFP that will be used to cast bullets from practice/plinking. I hunted last year with my NM Vaquero 45 Colt but for some reason that revolver and I never got along. It shoots great, but is very difficult for me to shoot accurately. So a few months ago I bought a new Uberti Bisley in 5 1/2" 45 Colt. We evidently were meant for each other! All I did was pull it from the box, work on the trigger, a little, and shoot it. Such a pleasant, accurate, easy to shoot revolver. My goal this year was to shoot a deer with a HP cast from the large/deep pin of the 45-270 Miha mould. I cast these bullets from 70/30 lead/WW alloy. They're loaded over 16.5 grs. of 2400 and run 1040-1050 fps. Last Thursday a little bunch of javelina showed up again, and again the deer fled. I'd just about had it with them, so plunked one of the .45 slugs through the lungs from about 45 yards out.  No expansion evident and penetration was through and through, but the little rascal was dead, so I was happy. This morning, a spike I'd been hunting for weeks finally showed up. Since we only have one deer in the freezer this season, I had to have him. I put one high in his shoulder from 48 yds. out. He dropped on the spot. I got him dressed and hung in the shop to cure for a few days and began the informal post mortum. Much to my glee, there was a bullet under the skin of the offside shoulder. Talk about picture perfect!   Regarding the Penta HP bullet, I moulded some for my .44 Special and fired them and some standard HP's from the same mould into water. The nose did indeed break in to 5 pieces while the remainder of the bullet penetrated 5 gallon jugs. Impact velocity was about 925 fps. I was a little disappointed but a handgun savvy buddy of mine wisely pointed out "..that's pretty much how Nosler Partition's work, you know." He's right! I may have to try them next season. CHT |

Which bullet is that HP? What is your alloy?

Which bullet is that HP? What is your alloy? Detailed in the post. It's the Miha version of the RCBS 45-270. The HP is from the "large" pin that comes with the mould. Alloy is 70% lead, 30% WW for roughly 9.5 Bhn. |

Nice work Cholla! I have some of these cast with the smaller round pin that I powder coated and wanted to try about 1150 or so in the Casull or other 45. Just haven't had time this year.
We are running a buy on that mold now Mark.
My favorite all around 45 bullet for deer and pigs. The recovered slugs on these 70/30 mix slugs sure are good looking and consistent!

Cholla, very nice work on both the Javelina & the buck. That 45 slug worked perfect on both. The picture of your recovered slug looks just like a bullet advertisement! I've said before if people would shoot that 70/30 alloy more often at the correct velocity they would do so much better because their accuracy would increase from reduced recoil, yet the load works fantastic. The Penta HP's wouldn't be a bad choice for Javelina, coyotes, etc. but like I've said before the nose does blow off, so expect that. If you want more delayed expansion & more penetration the round HP is the way to go. Yours looks perfect, great job! Don't see how a jacketed bullet at 5 times the cost could do better than that.

Forgot to say, if you're shooting HP's you don't want to water drop them, that just makes them hard & a hard HP won't expand like you expect it to unless you really drive it hard. Again, with HP's its all about alloy hardness & velocity, they have to match.

Thanks for posting your report/photos, Cholla. Very informative. I cast with several of Miha's molds, most have the 3-pin set with them. My alloy tests 12-15 before casting and powder coating, but haven't had the opportunity to test the finished bullet on 'meat' as yet. Hopefully that'll change shortly. Thanks again for your post.

I've used HP's on game since I started hunting with handguns...... that would be about 44 years now. The early Lyman design HP's didn't work all that well and were very alloy specific. I started altering the SC pin diameter and shape on them and finally got set-up with BRP molds who produced what I wanted.... this was before he went into business. MP molds came along and really got things going. I normally shoot 50% WW / 50% Pb, air cooled and water dropped in handguns and rifles with better results than I can buy. The bullet nose walls have to be a certain shape and thickness to initiate expansion. Depth of hollow point along with alloy control the rest. Normally, I get complete penetration of deer, sometimes that is length ways. That Nosler partition phrase was coined from the owner of BRP molds, and it's quite true.
