Hello fellow casters and reloaders,
I have a Mihec 434-640 mold that I've cast up some bullets with. Solid, they weigh around 275grains using range scrap. I was wondering if people have any experience with this bullet in the 44special. The "640" nose profile seems to be well regarded by a small group of people, but I'm not able to find a whole lot of information about it. I'm imagining that my Google-fu is weak, as I'm sure there's stuff out there.
I also have all the different pins that come with it. Ideally, I'd like to go deer hunting next year, and I'm wondering if this is a good bullet to start with. Your thoughts are appreciate.
Nate

Use the large hollow point pin and try for a 8 BHN number or a little less. Not knowing what your range scrap is, you can cut it with pure to make it softer. A good alloy is about 35:1 lead to tin. Loaded warmly, you won't have trouble killing a deer with it.
As for the 640 moniker, it was taken from the Lyman 429640 designation and instituted into quite a few designs.

Well, you don't say if it is a plain base or gas check or if you intend to powdercoat.
I would say, size it so it fits your intended cylinder throats. Try air cooled bullets first and see how your sixgun tolerates them at the speed/hardness you are looking for. Obviously you shouldn't cast 5000 or more before you test them.
Guys, you guys need to be base pin pullers. Pull your base pin and check your barrel for leading. Also look at your muzzle. You want to see a "star" of lube. This is telling you your bullet lube is making it all the way to the muzzle. A good sign for sure.
Get back to us. Let us know what you see. If you don't know how hard your cast bullet is because you don't have a hardness tester or don't know what size your throats are there are plenty guys here willing to pin gauge your cylinder or hardness check your bullets.

Excellent advice is standard fare from Bob. However, your particular sixguns dimensions and wants/needs will define what you can push down the barrel as to hardness and velocity.

Forgot all about that, Fermin. The bullets themselves are plain based and powder coated. The gun is a Freedom Arms 97 in 44special. They are sized to .429, as the ones I sized to .430 won't chamber. I have talked to the folks at Freedom Arms, and before I opt to send the cylinder in to be chamfered, they suggested I size down. The barrel slugs at .4295ish.
Thanks for all the input, gentleman, I appreciate it.

Thanks for all the input, gentleman, I appreciate it. Very good Nate, and thank you. FA's can be particular. I pretty much had every one I owned "treated" with Bobs reamer to smooth the bullet transition from threat to barrel. I would try thier "remedy" but won't be surprised at all if you have to open those throats to .430".

This seems to be a good place for Power Pistol. Maybe Longshot. Enjoyed the link to Fryxell article, thank you. I've been liking a bullet from Matt's that goes 250grs with a big HP. They, on 6grs of Unique are in my Bulldog now that's in my pocket. I think shot broadside into heart/lungs it'd kill deer just fine.

By all means sandbag at a minimum 25 yards. See what happens. The test for proper chambering requires the cartridge drop or slip into the chamber without force. David Bradshaw

So is this bullet a clone of the Lyman "Devastator" series? I'm assuming that Fryxel data is a good place to start. I was going to do 7grains of Unique, seeing as how it weighs just a touch more than the Keith SWC's I load with 7.5gr of Unique and shoot in this gun. I'll try the HS-6 as well.
Mr. Bradshaw, about the deep seating; How much reduction should I go? I estimate the front band on this bullet to be about a 1/10th of an inch. If I seat 20thousandths past the front band, how much powered should I drop? If it's 10grains of HS-6, a load from the Fryxel article (assuming this is the same bullet), should I go down to 8 grains? I'm very curious/interested in deep seating, just nervous about it.
Thanks again for all the advice, gentleman. Such a great resource for a novice like me, stuck in Seattle, with only Tactical Ted's to turn to. When I start talking about 44specials, their eyes glaze over and they look at me like I'm not speaking english.

I estimate the front band on this bullet to be about a 1/10th of an inch. The front band is between the crimp groove and the bullet base. what you are doing is sizing part of the nose in front of the crimp groove.

The nose in front of the crimp groove is full bullet diameter, correct? I'm starting to recognize that your moniker is implying that you designed this bullet. I'm very grateful for you responses to this thread. I read a lot of your posts on castboolits.com and they were very helpful. Thanks again.

That will size a little of the nose if done.I'm starting to recognize that your moniker is implying that you designed this bullet. Yes, I did. I'm very grateful for you responses to this thread. I read a lot of your posts on castboolits.com and they were very helpful. Thanks again. Thanks!
