Beeing a newbie on the board might allow me to get away with a stupid question like that. Did you ever think about a hard nose boolit contrary to a hollow point or soft nose one?
Most probably it was already discussed somewhere and I just missed it.
Ok here it goes: I don’t know it from experience but I am reading a lot about expansion problems with harder alloys and not effective impact on game with spitzer types. This is not a rating, again I try to learn and discuss ideas here.
Casting hollow points and their usage for hunting is discussed in several threads; as well there is a very good thread on casting soft nose boolits with a conventional mold.
It is just a thought experiment and I am looking to discuss this topic theoretically, since I anyway don’t have the means to try this, unfortunately. Let’s assume we take a well known caliber like 45-70 or any other big bore, it doesn’t matter. You are casting boolits that are neither spitzer nor flat point, you use something like the money nose, so rather a small radius round nose or something similar to a semi wadcutter with a small round nose. Now taking a medium main boolit alloy let’s say about 14 BHN for the main part and a harder alloy about 18 to 20 BHN for the tip.
You cast a small round ball resembling the radius of the nose, separately. During your main casting you take this finished round ball and drop it into the mold, it will align in center through the resemblance of the nose form and rest at the tip of the boolit. Afterwards you pour your main alloy. I am aware when no heat is applied furthermore there will be no bonding between the two parts.
Will there be a big difference with and without the bonding? Chances are the ball just falls off? You see, where my question goes. Could it be that this little ball in comparison to the rest of the boolit ( for instance .458” compared to .225” with the money nose) be able to aid expansion and still leave a massive enough shank to shoot through.
Maybe one could take a fairly hard alloy like 20 BHN and stick a 30 BHN tip to it and still have expansion? The usage of boolits with a better BC and still get expansion would work too?
I hope that I expressed the idea fair enough to get some discussion and ideas going on.
Just ignore, if it is too stupid a question.
