Casting 454 casull.

[Casull]

Hodgdon has data for a 335 GR. CPB LFN GC bullet. About 22 bhn + heat treated? Like > https://www.midwayusa.com/product/1010706565 View attachment 888944 lol, what a bad example.

Rotometals - The Brinell Hardness of this Linotype alloy is about 22.

Some special lube from http://lbtmolds.com/Home/tabid/5805/Default.aspx Read info on the website, may help.

And more http://www.beartoothbullets.com/index.htm

Just trying to point you in the right direction. My BIG GUN is a 44 mag. Good Luck.

Does linotype contain too much antimony for me to use raw? The lyman casting handbook tells me to use it. For pressures up to 43,000 psi. I hear i shouldn't use more then 6% ant. Does that rule of thumb matter with target shooting?

No.

The General Consensus is a bullet that is to hard will lead the bore. I run a test with pure linotype & oven heat treated in 45 acp & 44 mag. Target loads to maximum. No leading. Bullets can not be to hard, if of the correct diameter. Imo.

Make some bullets from linotype & see how they do. We can speculate forever but no two guns are the same and what should work fine sometimes doesn't . sometimes things work great that shouldn't work at all. Or cheat, install gas checks and it's unlikely you'll get leading if they're generally sized properly. Like I mentioned before on this thread, I load and shoot lots of 454 casull every year, never bother with anything harder than 15 bhn, zero leading - those are gas checked 360 grain (bought bullets) running between 1400- 1600 fps (1600 is an estimate, from a 10 " barrel VS the 5" barrel I developed the load with). Works for me, may not work for you. Any idea what size your chamber throats and bore diameter are?
Even if you do get leading, it's easy to remove.

 

[Casull]

No.

I was hoping you would chime in. Thanks

No i haven't got passed the alloying practice phase yet im still confused with my results compared to others. My mix seems like its softer then what im told it should be. Ill slug the barrel and chamber once i figure the casting part yet. Im suffering from some kind of newby syndrome. Im just going to throw the confusing part out the window and cast a small batch of bullets and bring them and my reloading stuff to my property up north and start slow and shoot test and repeat until i find my sweet spot.

That's good, make some and test them. You can even buy some of a known hardness and check your test equipment and then load and shoot those until you figure out what you need to do.

Thats what im gonna do buy some of a known hardness to rule out the possibility of my tester being off.

 

[mrawesome22-250]

Hardness isn't going to make a bit of difference if the dimensions of the gun aren't correct. If the cylinder throats are smaller than the barrel groove, you're gonna get leading. If there is a constriction where the barrel screws into the frame, your gonna get leading.

If the cylinder throats are larger than the groove diameter, and there is no constriction in the bore, you'll get great results even with bullets in the 10 range BHN. That is as long as you size the bullets to the correct diameter.

454 Casull @ 65,000 PSI maximum, needs jacketed bullets.

you'll get great results even with bullets in the 10 range BHN.

More proof from the internet that the BHN does not matter. As well, we all know 22LR bullets are pure lead and work well.

The only way to know is ,DO YOUR OWN TESTING.

All in my new book, "Mysteries of Cast Bullets" Coming soon. NOT.
