Mil Surplus reloading components?

[Sunray]

"...Your powder doesn't look like..." Please reduce the size of your pictures. You can't tell anything about a powder other than its colour and granule shape by just looking at it.
Did the guy not tell you what powder it is? If not, throw it away. "It shoots like Reloder-15." means nothing.

I dunno about that powder..........frankly, if you dump a little Unique on a paper sheet and examine it you'd have the same initial reaction....it SURE looks like a mix of powders too.

If that stuff was sealed and from a reputable vendor I'd rely on his rec's...........one thing tho, when you use surplus military powders do be aware that LOT # is everything!..............I use WC 846 for a number of cartridges and I always drop down substantially when I open a new cannister ............sure it's supposed to be very close to BLC2.......but 846 will vary by lot. I have had primer pockets swell from loads that were absolutely safe with a differing lot and found that in some cases a substantial reduction in charge gave me identical velocity to the heaver loading.

Take your time and work up your load with your components.

You can tell the powder in the picture isn't Rx-15, can't ya? If not, I need to send a bigger picture, not smaller.

A member on AR15 apparently bought this powder from Camp Perry under the pretense it was Rx-15.

Here's a link to the thread:

"...need to send a bigger picture..." It's about how long this page will take to load for a member on dial up service.
And lots of powders look just like that.

 

[Scott_R]

Rx-15 doesn't.

I've pulled down rounds with powder that looked like that.

I checked my mil surp powder against a canister of Rx-15 that I have, and they look exactly the same.

By the way, Seedtick, how does the math go to figure that a 1/3 of a turn of a FL resizing die is .024 inches? Not doubting your word, just curious about the computation. Or is that a measurement of experience?

Hey Jasper, No problem.

You just divide 1" by the thread pitch and that is the lenght of one complete thread.

Standard dies are threaded 7/8 - 14 UNC.

That means it has 14 threads per inch (pitch).

So 1 inch divided by 14 equals 0.071".

For one complete (360 degree) turn the die moves .071".

And 1/3 of that is about .024".

HTH

Hey Seedtick, that's some useful math there...I am a high school math teacher, but we hardly ever get into the practical use of math like this, and I didn't even think about converting threads per inch to inches of travel up and down.

Thanks,

Jasper

math, practical? Who'da thunk it.

That's the kinda stuff I used every day (machining work) for most of my adult life. Another thing that's helpful/practical is that when I see a common fraction, say by 16's and 32's of an inch, I see decimal the equivalents. Although, I will admit that it takes a lot longer to see them now than it use to. :banghead:

Well, as far as that goes, it takes a lot longer for a bunch of things anymore.
