This is an interesting thread. I will add my 2 cents.
After using hp on many deer sized animals and varmints with revolvers, I have come to the conclusion that the best design for deer is a hp and alloy that holds together. First of all you don’t want to lose any weight in a bullet that already has lower sectional density than say a rifle bullet. It just limits penetration too much. Second, I don’t see much effectiveness from petals that break off. They never get far from the wound channel because of lower velocity. So all that really does is limit penetration because it lost weight. So when sectional density is low and velocity is low, you don’t want that bullet breaking apart.
However the exception is with varmints. It doesn’t matter with them and their small bodies are affected by fragmenting types even at low velocity. I have seen that the game changes when velocity and sectional density goes up like say a rifle design at 2000 FPS. Now you can take advantage of the speed and sectional density. Fragments travel farther in the animal and you don’t lose as much percentage of weigh so penetration is still good. I would use Dicks formula for revolvers and cast and try to keep the bullet together.

Fragments travel farther in the animal and you don’t lose as much percentage of weigh so penetration is still good. This is somewhat different than I have seen on deer I've shot myself with handguns. We have several rules using them.... caliber and 500 ft.-lbs. of muzzle energy. I have only recovered one HP slug to date and that one went thru a large bucks shoulders to the off side skin at about sixty yards. Even the minimum ft. lbs cartridges went thru and left a hole you could put two fingers into the exit wound. Our deer are corn and bean fed weighing anywhere from 100 pounds to a small doe to close to 300 lbs for a very large buck. I've shot several deer with Keith type solids, but you can expect a 100 yard run or over unless you break them down. HP's of my design limit deer travel to about 30 yards if that. It's no problem shooting thru a deer at all. The difference in impact on a deer is quite noticeable as they look like the got whacked good while a solid Keith style they show little shock and leave fast. |

Here's my bullet for the 350 Legend. It's a 35 caliber designed by boolitdesigner and is 217 grain hollow point. Already shot it and it's a humdinger. I think of my 350 Legend rifle as a 35 Remington AR15. Yes another Mihec mould.  |

The hollow point vs solid discussion is valid when comparing like cartridges. However it is not as important when comparing a big bore cartridge. My deer load for my 500 Linebaugh is a 355gr .425" meplat wfn at 1350fps. Double lung broadside usually drops drt. Longest I've had one make it is about 15 yards. My pet 357 deer load is tha MP version of the 358429 cast with the large hp pin loaded on h110 for 1300fps. Same double lung shot and they never make 30 yards.

I could not find that mold mentioned on the MP website. Do you have a mold number?

That is the correct mold. Originally it was for the 35 Remington.... an about maximum weight to be used in it. It was done originally by BRP. It is a very good shooter in the 35 Remington, 35 Whelen and 350 Legend. We use it in HP form. MP molds is the current producer.

What would a 7mm (.284”) from Miha look like? He “needs” to make something for us 7mm users...would it be based on 312-159 Hunting with its HP/FP or something totally new? I am using MP’s 312-159, 311-180 and 311410, plus #38 Ness safety bullet in my 300 BLK. Some nice brass mould would be nice to feed my 7x64, 7x65R and 7x57R... Any news about that 7mm mould? Do we have design at least?  |

7mm has several versions of chambering that doesn’t match well…. much like the 30 & 31 caliber cartridges except the newer 7mm chambers are to different throat specs. One thing only fits part of them and another fits something else. Nothing matches well……

Just to give you two examples I have a 7mm-08 and a 7x57 Mauser. The 08 has an extremely short throat, the 7x57 extremely long. SAAMI did shortened, or someone, the throat on the Mauser, but not by much. I'll describe a bullet that fits my 08 very well and that is the 130 grain Lee. It shoots extremely well from my 08 and at jacketed bullet velocities. With all the new fangled 7mm cartridges and throats, it would be impossible for Bob to design one bullet for it.

Has the 359-640 been offered with a gas check shank? The 357 CARB bullet looks like it is a different nose than the 640. Please correct me if I am wrong. Use would be for my 357 Max Rugers. Thanks!

It has been when it originally was run. Now it is in a plain base mold. The 357 Carbine was offered in both also. I’m shooting the carbine bullet in 357 rifles water dropped from the plain base mold with no problem. The noses are different and are both “640” style nose designs. |
