.44 Remington magnum question

[Shuz]

44Blam--What boolit and how much Trail Boss do you use in your .44 mags?

[Catpop]

Shuz,
Because .429 boolits lead terribly!
.430 also lead terribly!
.431 also leads but not as bad as above two
.432 also leads but is almost manageable without choreboy.
A .432 swages to .4315 through cylinder.
I will open throats to .432 next
If still leads, I will open throats to .433 and shoot .433 boolits which should elimination the leading issues
This process is followed with all my revolvers and is a procedure developed by a west coast master boolit maker and then sent to his east cost testing labs for extensive range testing.
It works, what else can I say?

Out of curiosity what is the name of that west coast master bullet maker? Is he still making bullets?

44 mag,
I’d love to give you his name, but alas I am sworn to secrecy!
I have however informed him of your inquiry and he may contact you.

My mould is Accurate 43-240A for PB and 43-240-AG for GC boolits. I powder coat (mostly) and size to .430. I load the PB ones with Trailboss and I use 6.5 grain and I load my GC boolits with 23.5 grn 296 or 21 grn 2400. The TB boolits shoot with zero recoil - the others well they do kick a bit.

I use HS6 as the bridge between 8.5 gr. of Unique and 2400 and H110 or WW296, not more unique.

Loaded up a few of the 200 grain with 11 gr. unique. Had more kick then I expected from what I thought was a light load, shot wide to left at 10 yards, and upon examination of the brass, on case had a split towards the bottom of the case, which freaked me, as Ive only seen pics of this happening, never in my reloading. Was 11 gr. to high, and I'm wondering, can I over crimp? Using lee factory crimp die. Lymans cast bullet manual #4 should be here today. advice, please.

[Shuz]

Catpop--I suggest you stick with .432 diameter boolits with a soft NRA type lube and your leading problems could go away. However,it seems to me with a .429" bbl, that what you really need is a cylinder that measures .4295 or .430! You are asking a .429" bbl to swage down a .431 or .432 diameter boolit without any leading?

[Catpop]

Shuz,
Thanks for sharing your hands on experience with me!
I’ll keep it in mind as I continue my testing!
