Well I was trying to post the screenshot shots but didn't wanna upload so here's the link

I need a bigger screen to read it. I'll look when I get to a real computer.
I did some 405 gr for 45-70 with 85 gr pure lead and the rest was bhn 12. Haven't killed with them yet. I dropped an 85 gr 257 cast with pure lead into the 458 mold, heated til it melted, then topped with bhn 12. Wasn't difficult. Was time consuming. Not even sure if there is a benefit over standard harness.

The posted stuff above is not inconsistent with the "RPM theory". The theory involved states that there is a 'limit' at 140k for .30 caliber bullets. It is not a hard number as there are several variables at work. Smaller dia bullets have a higher max rpm. A small change in dia means a lot of difference based on the variables involved. I am not surprised at results using 6-7mm bullets.
I have fired .30cal bullets at 2400fps in a 10 twist barrel. Most of the time the accuracy is worse than at
If ya think it'll work for you, I'd encourage doing it.
Personally, I wouldn't bother, especially for target shooting at paper.
For hunting: It looks like a lot of extra casting time, can introduce unwanted variables at worst,
and brings minimal gains for all the effort at best.
When I was still hunting, I didn't over think and split hairs over doing stuff like this.
I concentrated on accuracy, trigger control, shot placement, and was sure to 'bring enough gun' for what I was doing.
It's an idea that has been around for a long time and various methods have been tried. No first hand experience but would be interested to see how they compare to 10-1 lead/tin bullet that is paper patched or PC'ed
Been down that road both with the 2 part bullet and the claimed velocity/accuracy. Also had numerous discussions with Von Gruff regarding such. As mentioned, you want to give it a try then go for it......good luck.
It could be fun experimenting with the concept, but otherwise I think just going with a gas checked soft boolit is the most practical.
I remember reading about this concept here a few times. But the discussions are normally dropped soon, indicating to me that while "duo-alloy" bullets may work, the payback isn't consistent enough for all the extra work involved. Many replies mention bullet shape and placement outweigh possible expansion from cast bullets.
But honestly, if one would like to find out if they really work for them, try some...
If you're looking for more expansion, check into making hollow points, and the different levels of hardness for them.
They're a little more tedious and a little slower to produce than solids;
but not nearly as slow as the multi alloy boolits while trying to keep them even close to being the same weight.
Heck, why not just buy some Sierra 165 gr HPBTs and go hunting? Good accuracy and excellent performance. Is four hours of labor worth the $35 you'd save?
Sometimes it's just about the knowledge gained from experimenting and not the end result.

If weight variations are a consideration, just cast a sufficient amount of the two alloy bullets and then weight sort into groups before you lube and size them.
I have to wonder if anyone will ever search and find this thread given the subject term "welded" bullet which is about the first time I have ever seen it in a thread.
Yeah, I'd never heard the term before either.
That's why it sort of caught me eye. Plus, I really like following the trials and tribulations of the new kid..
I'd never discourage anyone doing research and experimentation.
However; sometimes ya just have to recognize a blind, dead end alley (for your own application) when ya see it.:bigsmyl2:
I believe Bruce B did something similar. I did cast a few soft pointed bullets but California won't let me hunt with lead. Oregon is friendlier. Will load up the cast duo boolits if I can find them after the move settles out.
