432640 Loads

[newton]

Anyone have loads they will share and how they perform with this boolit?

I know there was a group buy that happened a few years back for an NOE mold listed as the 432640, now on their website as the 432-295-FN. It was based off a Lyman Devastator but with a solid nose.

I have the Lyman Devastator mold and made a pin to cast solid nose boolits, and so I am curious what others have now settled on as good loads with their boolits.

The other day I got some decent groups with 20gr of W296 and a CCI350.

How about you?

I use the Devastator on deer because it works. Your load is not much different then mind.
I load 19.6 grs. of 296, with Federal primers.

[Larry Gibson]

I use the Lyman Devastator cast of 16-1 alloy. Fully dressed it weighs 275 gr. Over 23 gr H110 in WW cases with a WLP primer it runs 1486 fps out of a 8.4" Contender barrel at a Measured 30,200 psi. Out od my 6 1/2" barreled Ruger BHFT 50th Anniversary it runs 1360 fps.

those are some good looking boolits! would they benefit from a slightly smaller " mouth" to the hp, or do they stay togeth like that, at those velocities?

[Hickory]

16-1 lead-tin stays together pretty good at 1200 fps for me. Unless it strikes bone.

I am kinda really looking for the non hollow point load data. I don’t know if 15gr or so weight difference would matter too much. My boolits are weighing around 290gr fully dressed.

hey newton, have you noticed an increase or decrease in accuracy when dropping your powder charge? I will have to re load some to double check, but seems like I might have gotten a bit better accuracy at 21.5 grs, I am now at 20.5, which is more pleasant to shoot, so I might try 21, and see if it helps any. I wouldn't think 15 grs would make much difference, in an article about heavy 44 mag boolits when the author went from 300 to 320 he dropped from 21.5grs of 296 to 21grs, so you might drop 1/4th to 1/2 a grain for those solid points, but I doubt it would put you over pressure if you didn't, since I don't think you are running max loads. good luck!

I actually did notice an increase in accuracy when I increased the charge 1/2gr. That’s why I’m curious about others loads for this boolit. I wouldn’t think that much weight would make a difference either, but the last thing that most people say before an accident is “I didn’t think....”. Lol

Larry’s testing pressures with the same boolit, but with a hollow point, makes me feel a little better in trying a little higher charge to see what happens. I honestly think I could go up to 21gr, but it would make me feel better to hear from others who have gone before if you know what I mean. :)

Lyman's CBH #4 has 296 data for 265 gr and a 300 gr cast bullets. A max load of 21.5 gr pretty much splits the difference between the max loads listed for their bullets. Given you bullet is closer to the 300 gr bullet I would cautiously work up to 21.0 gr with a 290 gr cast.

[Oklahoma Rebel]

but I have noticed a huge difference in their velocities, thos in lee's book, and also various articles I have read. it seems that lymans posted velocities are lower than what is really experienced by others. does anyone else notice this?

[Mr_Sheesh]

Folks, PLEASE do us all a favor & specify what caliber you're talking about loading for? I'd hate for someone to be asking about 44 Special loads and end up putting a heavy 44 Magnum powder load - or worse yet, a 444 Marlin load or something - into a Bulldog or the like. I figure we all know to double check things, but good practices are good practices :) And we can have bad brain days. Call me paranoid if ya want but accidents really SUCK!

When you read load data it will behoove you to look at the testing methods. Not just the data. If you will notice Lyman uses a 4 INCH PRESSURE BARREL to record velocities for some time now.

I guess I could see that. It is for a 44 magnum in my instance.

[Oklahoma Rebel]

ah, I do remember reading that , now, of course! I had forgotten about that. by "pressure barrel" do you mean a remotely operated rig, and not an actual gun?

It is the barrel on the pressure testing device. Not an actual gun in the sense of a real handgun. The gun used to record pressure. Either CUP or Piezo Transducer. Lyman will list the barrel if it is a regular firearm. By the make of firearm and barrel lenght.
I know someone will come on here and use technical jargon that will sound highly educated and amazing to some but what i said is the jist of it. Kinda like Doc Adams arguing with Festus Hagen.

[Oklahoma Rebel]

ok, I get it, I think I have seen them use one on tv before

[Oklahoma Rebel]

newton, I weighed my boolits, and I guessed pretty close! they weigh 275grs as cast with my alloy, 2%sb/4.5%sn, and with 21.5grs of 296 I didn't see any signs of high pressure, so I think you will be fine going to that, any further, and you're on your own! lol, but if you are like me, which I think you said you were, 21.5grs of 296 is about as much as I would go, while still being able to enjoy shooting it!

I got in on the Mihec 434640 for my Marlin 1894.

The boolit feeds and shoots well. I generally load it over IMR4227 because that is what I tend to use for .44 mag. .308 and .303 Brit. All in all I like IMR4227 and have for many years. Not going to make spectacular claims other than it works for me!

The Mihec mould is nothing sort of spectacularly well machined and casts perfectly so a plug for Mihec!

longbow, is that a plain base or gas check boolit? someone told me that 4227 doesn't work well with plain bases, that it can deform or gas cut the bases, have you ever noticed this?

I would consider the source and then run.

[longbow]

Yes, PB boolits. I only have one GC mould for the .44 and that is the Ranchdog 265 gr. because I couldn't get it in PB.

I will agree that I've had some gas cutting on the base driving band that I find to be a bit of a mystery... well, sort of.

I started out life the Marlin casting and shooting the Lyman 421429 which cast undersize in my alloy so gas cutting was a given and in that case accuracy was poor. I fattened boolits up once I realized that and did much better but even my smooth sided boolits from a push out mould sometimes show a little scalloping on the edges of the base with heavy loads. No leading issues and generally pretty good accuracy (for a light lever gun with iron sights and semi competent shooter).

I do not actually recall if I have recovered any of the 434640's to check for gas cutting but I don't think so. I have recovered boolits from a couple of home made moulds, my Mihec H&G #503 and the Lyman 429421, all of which have shown this minor scalloping with heavy loads and little to no scalloping with anything less then max or near max loads. Also, I can't say for sure that I didn't get that same minor gas cutting with other powders. It doesn't seem to hurt so I haven't worried about it. Only a bit of scalloping on the base band.

For the most part I have loaded right up to jacketed max. manual loads for same weight bullet using cast PB boolits with no significant issues and for the most part using IMR4227 because I like it. H110 I think can give higher velocity than IMR4227 but is not as flexible for downloading or for use in my other calibers.

I say a bit of a mystery because mostly it is just the bottom edge it doesn't generally make it past the base driving band so I'm not sure how you get gas cutting without complete passage unless the grooves get microscopic further along the shank?

Having said that, I use IMR4227 under PB boolits in my .303's too.

interesting, I have checked the base of my boolits fired with 20.5-21grs of 296, and it shows no cutting, and only the tiniest bit of "skirting" where the lands meet the base, and I mean just visible if you hold the boolit at the right angle... that would lead me to believe that I am sizing them just right, I think?

[bluejay75]

I have found that under compression that 4227 left imprints of the powder on the base of the Boolits. I found this by chance when shooting into my Boolit trap seeing if I could get expansion out of straight WW at 44 mag rifle velocities. Not sure if it adversely affects accuracy...but it couldnt help it.

[Oklahoma Rebel]

I wonder if the imprint is formed when you compress the load or when you fire it.... how soft is your boolit alloy?

[44MAG#1]

Dont you guys think you are over thinking things? Come on now. Its fun to think but it can be over rated at time especially this type. But on a cold night it can be fun. I watch TV or something.

[Oklahoma Rebel]

most definetly, unfortunately I too often overthink things, that's why i need you to tell me when to give it up!:razz:
