Lyman 356634 Over All Length & Powder Data

[deltaenterprizes]

I am having problems finding load data for this boolit and it was suggested that the Lyman 47th or 48th manual might have it.
Does anybody have either of those?

What cartridge?

I load mine to 1.016-1.020. I use 3.8 grains of Unique. Now that I have adjusted my seating and crimp dies properly this combo sized .356 and lube with Orange Magic function 100% in my G17 with Wheaton Arms barrel. No bad pressure signs on the primers.

I tried some sized .357 again with 3.8gr. of Unique and lubed with Jakes Moly Ceresin in my Ruger PC carbine. 100% function and Excellent accuracy at 25 yards, better in fact that Federal 124gr. FMJ. Some leading with this combo leading me to experiment with .358 sized bullets. I will try some more .357 sized in my mini Beretta Cougar.

I have some sized .358 lubed with Thompson Red Angel waiting to test in my Browning HP and Ruger PC carbine. This combo is awaiting mynext range visit hopefully tomorrow.

Also the load data I found was actual Lyman data that was in one of those one book one cartridge books. I chose Unique because that was the only recommended powder for that bullet I actually had on hand. I am pleased with Unique for this boolit.

I cast these with Rotometals #2 Alloy which yielded as cast boolits .3585 weighing 129.2-129.4gr.

When my grubby remelt alloy which was mostly hardball, was used these cast at 131.1-131.4gr. I think they as cast at .3575. Those bullets were sized .356 for my G17.

I prefer #2 alloy for this bullet but its expensive.

I’m curious if your mold is dropping Boolets at .3575 why did you try to size em at .358? Are they even touching the sizing die? I guess I’ve been lucky with my molds and alloy. I don’t have that particular mold but the five or six .356 molds I do have have never dropped boolets.002 over specified diameter. Anyway just curious

[Divil]

To answer your question my measurements are done with a set of calipers because I don’t have a micrometer. When I used the #2 alloy I got the .3585 as cast diameter. The best looking of those bullets I reserved for .358 sizing since touching is minimal. The uglier bullets with the #2 alloy get .357 or more likely .356 sizing since that may take a little of the ugly out and leave nice clean looking boolit sides.

Since #2 alloy is expensive, I cast one session worth of remelted commercial cast bullets and previously cast boolits using mostly hardball alloy. They weighed a bit more and all were sized .356 for consumption in my G17.

A friend has a Lyman 47th edition and sent me a copy of the data!

[Divil]

Glad your friend was able to supply the data.

Below are my #2 Alloy cast #356634 bullets sized .358 and lubed with Thompson Red Angel.





Below are the results of 2 17 round mags in my Ruger PC carbine at 25 yards using the .358 bullets with 3.8 grains of Unique. Yes I need glasses.



Finally are the .358 bullets again with Unique. This time 13 rounds at 17 yards out of my Browning HP with factory barrel. I just cleaned the pistol and found no evidence of leading with this combination!

[Divil]

Just cleaned the mini Cougar 9mm. Using .357 boolits with Jakes Moly Ceresin lube and Lyman #356634 boolit it had the absolute faintest leading that was removed with regular hoppes #9, minimal scrubbing and 3 patches. I have scrubbed more using cheap FMJ ammo (just the low quality stuff) with this pistol to get it clean, so I am satisfied with the cast boolit results for now.

I also cleaned my Ruger PC carbine. In the past .357 sized boolits did produce stubborn leading. Using .358 sized boolits lubed with Thompson Red Angel there was no leading at all. In fact I have never seen such a clean bore in a fired gun. Granted I only fired 34 rounds but I was still impressed. Just 1 wet and 1 dry patch and the bore was pristine. I have never had that happen before.

Forgive me for saying, but your 3.8/Unique powder charge seems light. That's a starting charge for a 147gr. projectile. Are you intentionally working up a very sedate load? Or are you just erring on the side of caution, for lack of loading data, for this particular bullet?
BTW, that's one VERY nice looking Hi-Power!

[Divil]

The Lyman data I have lists 3.5-4.0 grains of Unique for that specific bullet. I understand that it seems light however, the bullet seats short at 1.016-1.020 perhaps this keeps the pressure sufficient to develop adequate slide and bullet velocity. This load combination reliably cycles in my G17, BHP and Ruger Carbine.

Thanks for noticing the BHP! Its been a work in progress, adjustable sights are next!
