Wait a minnit... There's an MSDS out on that model:
Woman
Material Safety Data Sheet

MATERIAL SAFETY DATA SHEET
WOMAN - A CHEMICAL ANALYSIS
Element: Woman Symbol: Wo Discoverer: God-An improvement of a prototype, Man Atomic Mass: Variable, between 85 and 550 pounds, with 120 lbs. being an acceptable nominal weight.

OCCURRENCE: Occurs world wide, often in a racemic mix with man.

PHYSICAL PROPERTIES:

1. Surface often covered with a thin painted film.
2. Boils at nothing and freezes without reason.
3. Melts, if given special treatment.
4. Bitter, if used incorrectly.
5. Found in states varying from virgin metal to common ore.
6. Yields to pressure applied to correct points.

CHEMICAL PROPERTIES:

1. Has high affinity for gold, silver, platinum, and precious stones.
2. Absorbs great quantities of expensive substances.
3. Insoluble in most liquids, but reactivity is greatly increased if saturated with alcohol.
4. Most powerful money reducing agent known.

COMMON USES:

1. The rough ore is especially useful as ornaments when applied to sports cars or sailboats.
2. In its more refined state, it serves well in the job market at a reduced cost.
3. Also, in most of its intermediate states, it serves well as a support for Man.

TESTS:

1. Pure specimen turn rosy pink when discovered in a natural state.
2. Other specimens turn green when placed near a specimen of higher quality.
3. Higher quality specimens react exothermically when placed in contact with newly created versions of either enantiomer.

HAZARDS:

1. May explode spontaneously without prior warning, and for no known reason.
2. Extremely dangerous, except in experienced hands. Even the experienced should exert extreme caution.
3. Except in portions of Utah, one should not try to maintain more than one sample of this element.

Made some sand bags and man did they help. I may make a few more to get things even better.
Loads were all 21.5 H110 in cut down 445 cases.
10 ea with CCI 350, Fed 155, and Fed 150

I will get photos of targets up later.

Fed 150

Recovered bullet. This was heat treated range scrap. BHn 18
I don't know how but it looks like the bullet isn't entering the bore straight. The check shows a little lead buildup on one side but not on the other. The grooves are smeared towards the rear on one side but not the other.
I wish I could have recovered another bullet but the berm wasn't giving them up easily.

 

[Ian]

Looks like you're experiencing involuntary thumb spasms in a bad way, did you notice that?

 

[Brad]

I did notice that. I have a family history of minor tremors, my father and older brother are far worse than I am. Amazing what video shows.


Quite easy to see the difference in the shape of the grooves after recovery.

The side with squished grooves has a clean check.


The side with more intact grooves shows lead wash on the check.

Sure looks to me like the bullet was not centered in the bore. It isn't for lack of throats contact, they require a firm push to chamber fully.

Thoughts anyone? I wonder if the forcing cone isn't quite square? I will look hard at that. I have never noticed this effect on ANY bullet recovered from this report evolved and I have recovered hundreds from it. Kinda has me baffled.

 

[Ian]

So that lube groove tapering closed on the RH side of the picture isn't just optical illusion. Thanks for posting the extra pictures, I'm frankly amazed the bullet could hit the target being in such bad shape and the base so out of square. How it could get that far off, having nowhere to displace that much inside the revolver, has me totally flummoxed.

 

[Ian]

Wait. Didn't you have the forcing cone reamed on this one? 11° or something like that? Any chance the cylinder is unlocking under recoil?

 

[Rick]

Don't discount damage to the bullet by impact with the birm. The forcing cone and/or revolver timing could also be an issue. Everything adds up and magnifies at longer ranges and higher velocities.

In the first video it looks like your canting the gun to the right. Could be camera angle but . . .

 

[Brad]

The canting is largely camera angle. The GoPro is mounted on the bill of my hat. The camera had a really wide field or view and that distorts things a little.

Rick, I am wondering if impact is what caused the differential lube groove collapse. The bore of the revolver hadn't been cleaned in hundreds of rounds and a few wet patches showed no lead at all.

Ian, the forcing cone was polished by yours truly. Gonna scare you but I used the Al cone shaped gizmo that came with my Lewis lead remover and some abrasive grit. I used a muzzle guide to keep the rod centered. I must have done that work 20 years ago?

The CCI looks good with this load. The other primers look to need some small powder changes. I want to further investigate the Fed 150, it has given good results in the past. I may try going up .3 gr or powder and see what happens.

Rick, and suggestions otherwise on powder? I have maybe a pound of N110 and lots of I4227. I have a bunch of 1680 but that is awful slow for this cartridge, or seems to be to me?

 

[Ian]

Rick, no way the collapse is impact damage, look at the engraves!!

 

[Brad]

Good point Ian.
This may be time for me to try adding some tin to the alloy. Might change the way the bullet flows under pressure.
A slower powder would be tough unless I went with 4227 or 1680. I don't know if the case would hold enough 1680 for a good burn.

 

[Brad]

Velocities are as follows
CCI 350- 1307 fps
Fed 155-1206
Fed 150-1219

Kind of interesting that the Fed 155 was slower than the Fed 150. We assume that a mag primer will give more velocity but not always.
The CCI is certainly the king of velocity here.

 

[fiver]

if you look carefully it appears the bullet is bent slightly,,, banana bent.

this is the slightly beefed up version of the last ones, the ones that were losing all of the grooves?

either way I'm gonna go out on a limb here and suggest you look closer at the gas check.
and look at it from the base.
and maybe look at it like it needs annealed.

 

[Brad]

I just checked the hardness of the bullets used today. They measure 23-24 BHn.
I have some newer ones cast up that measure the same but the will get a different lube.
I had modified BR in the Star but switched to an SL68b variant to reduce smokiness in some other loads. Not sure it will make a difference but lube certainly can.

 

[fiver]

it can and not just in laying down some lube in the barrel.
it can quite often make the difference in support of the lube groove.

 

[Ian]

Air pocket?

I'm beginning to think this alloy simply isn't going to work at these pressures, no matter how much you heat treat it. You run into the same thing with rifles, at some point you just HAVE to increase the antimony and tin a little.

 

[Brad]

The nest round of bullets are the same BHn but WITHOUT heat treat. The new ones are cast from ingots made from the mass of unused bullets I pulled from my loading room years ago. Many of those are from when I was under the mistaken idea that harder was better. Lots of Linotype in that alloy. These are air cooled and aged about 4 months.

 

[Ian]

Well, why not? I tend to favor extremes too.

 

[Brad]

I can easily cut the mix if it seems warranted. I need to size some and see if they cast much larger.

 

[freebullet]

either way I'm gonna go out on a limb here and suggest you look closer at the gas check.
and look at it from the base.
and maybe look at it like it needs annealed.

Seen you mention that before, mind elaborating? Is the thought an annealed check may obturate with the lead instead of deforming the bullet? Just curious.


I dunno
Our berms when dry are wildly hard & I don't think we can discount the damage from them one bit. I'd wanna catch some unexpanded before ruling that out completely.

I'm wondering if slower..much slower powder might help.
