429640 hp

[Ben]

I purchased a Lyman 429640 HP from arcticbreeze.
He had Erik make 3 different HP pins for the mold.
I have a Stainless Model 624 6" , 44 Spec. and a new Ruger 77/44
that I'll be trying this bullet in.

A very nice mold, easy to make very nice looking bullets. It drops
from my alloy at .432", just about perfect for my needs.

I weighed a few.....here are the weights :

Wow, those boolits look great. I am glad to see the mold get some use.

Enjoy

Thanks again Marc !

Wow Ben, that is a sweet and versitle mould!

I will be very interested in hearing how the Ruger does with boolits. What does it have for bore size?

Have not slugged the rifle yet ? ?
Hopefully it won't be larger than .432 "

Very nice looking bullets and a fine job of casting.
Not to mention the great work by Eric.
Now that the stroking is all done with--I have a ??
Do you think the nose is going to hold up, or will it blow apart.
Could it be to much of a good thing ?
Just asking so I know.

Don't count on it.......... Thin barrel with a very light stock..... VERY hard to hold if you want 44 Mag performance with accuracy. Keep us informed please.

I'm going to give this bullet quite a bit of testing before I aim it at a deer. I'm thinking about taking the " moderate HP pin " that you see below and remove a bit more so as to make a HP opening in the nose of the bullet that has somewhat thicker walls.



What do you think ?

PRETTY bullets from a nicely HPed mold !

Thanks Jerry ! !

I've completed my work on the HP pin to allow nose wall thicknesses that will be a bit thicker than those cast in the photos below with the " deep HP pin ".

Here is a bullet cast with the deep HP pin. Walls are pretty thin :



The new modified pin will cast bullets with thicker walls on the nose . This should allow for deeper penetration without the nose " blowing off " and I should gain a 2nd advantage of making the reject rate with this mold drop dramatically.



This 2nd photo shows the deep hp pin, notice how thin the nose walls are with
this pin.




Here is a view of the modified HP pin. Should make for a good white
tailed deer hunting bullet.

Nice job on the mold and most of all nice photos. What do you use for pictures? Thanks, Mike

Mike :

I use a Minolta ( a 10 yr. old Minolta )
It is like a Timex watch, it takes a licken and keeps on ticking.

Ben,
Those look great!
I am looking foward to see your test results on the three different styles.
I have the same mold and have done a removable conversion to make solids a while back that allows me cast solids without using a removable pin in the HP pin cavity. With this conversion it casts like a regular mold. Other things came up and I left the load development undone and went back to using my Ruger 45 Colt instead.
Your thread might be just the encouragment I need to get this started again.
Good luck, jmsj

I would use a softer alloy then say WW (12BHN) on the deep HP, In my tests the harder you go the more it frags.

[Ben]

I finally got around to casting with the modified pin. My goal was to produce a HP bullet with walls on the nose that were " a little more beefy ".

I'm happy with the results. The finished product weighs 274.9 grs. without a g/c or lube.

Ben, really nice job on all counts. I planned on doing something very similar with a Miha mold in the 429244 configuration. I've got the large HP pins for the 44 spl. and the smaller HP pins for the 44 mag. My best friend and I, along with several of our hunting buddies have killed a lot of whitetail deer with the standard 429244 boolits, but they always go all the way through and so we never recover the boolit. My current alloy measures 9.0 BHN and with the gas checks I should still be able to push them at 1200. With the HP, they should open up nicely and maybe we'll get one recovered this year.

HEY!! my wife says that about me!! Except she replaced ticking with talking...I take a licking and keep on talking!! Haven't talked to her in 10 yrs...and that was the day of our wedding (my funeral!!)

Honestly though, nice pics Ben

Looks like a nice boolit to play with

I have that mold and have shot a deer with it I used 16/1 lead tin at around 1400 fps with 17.6 gr 2400 out of a CVA scout rifle. Shot right through the neck. Found a couple real small lead fragments
