.357 Magnum Load Data

My old go to powder was Winchester 296. But after Obozo got elected and caused the powder shortages I had been forced to use Unique or Blue Dot since I had stocks of both of them. I finally did get an 8 pound jug of the Winchester so I am back to using it.

Bought a new mold for my .357: NOE HTC359-173 WFN PB (5 cavity aluminum) with a .~~300~~" .280" meplat

Alloy: Lead 92.5% + Antimony 7.5% + Tin 2 % = 17.9 BHN
Note: After PCing them I drop them in a bucket of ice water out of the oven which gives a BHN of 20.9 in 30 days.
Actual Weight: 169 grains
Actual diameter: 360"
Sized to: 358"
Length after sizing: .658"

Preheated on a hot plate and dropped four perfect boolits (one wrinkled) on the first cast and 583 later they look like this:

Time to powder coat these with "Clear" PC and mark them as "Werewolf Killers"

Now that silliness is out of the way, load development to follow.

Those look very nice!

I love NOE molds. Always good performers.

Nice looking bullets!

those look really nice--- I have a very accurate load with 158xtp's from my 6" RBH with H110--- clocks @ 1440fps, looks like you found a better powder than H110 though with that 300-mp

Hello
I did a study on 158gr Jacketed bullets a few years ago. Might find it interesting..
300-MP proved to be quite good in .357 Mag. The old standby 2400, H-110/296 were quite useful also..

Rdub the Buffalo Bore 158 JHC with 19.8 grains appears to be Lil'Gun powder. (Hodgdon shows 18.0 grains @ 1577 fps)

I don't know Shadow... That stuff was pretty weird looking. The photo really doesn't show how shinny it is.. Did you notice how 'clumpy' it is? Lil'gun is quite dull in comparison.. Never seen anything quite like what ever that is..

Here is the picture of Lil'Gun I took today...

Here is the one you posted...The clump was probably a compressed charge in the BB cartridge...

Well I weighed out 19.8 grs of Lil'gun and put it into a Winchester case and there is enough room barely for a 158gr bullet.
I suppose one could work up from 18.0grs to 19.8grs a few tenths at a time and see how it goes...

But, I'll bet we run into pressure before reaching 19.8grs. of canister Lil'gun. I'm willing to try it, but southern Oregon is currently on fire and the woods are closed down until we get some rain. No rain is sight for a while..

Your neck of the woods are having its share of troubles too..
