"propreitary" powders... :o

Viking and Barnesuser28,

The issue isn't what the OP choses to do with his rifle or his own handloads. The problem is his disemination of faulty, inaccurate and downright wrong information. As I pointed out earlier, this site is frequented by some very experienced and knowledgable handloaders, but it also has plenty of new guys who are just getting into this stuff. Part of the problem with the OP is that he seems fairly articulate, which masks the misinformation he's spreading with some degree of "credibility." What he's promoting here incorporates some completely erroneous statements, misinformation and some potentially dangerous assumptions. He clearly doesn't understand how proprietary powders come to be, how they may (or may not) achieve "cannister" status, or even the basics of how powders are made. He doesn't even have the terminology correct, which is rather important in a technical field such as this. For someone making proclaimations regarding how you can "duplicate" factory loads, I'd consider such knowledge to be a fairly basic requirement.

I've detailed precisely how this sort of misinformation can be dangerous, and can most definately result in damage and injury. Over the years in this industry, I've seen any number of "inveterate tinkerers" manage to screw up their firearms, and occasionally themselvers in the proces. In the field of ballistics and firearms, I'm a court accepted expert witness in several states, and have testified in many criminal and civil cases over the years. A great many of those civil cases were the result of these homestyled tinkerers going off track and trying such ill-advised ideas. Some of them seem downright comical to an experienced rerloader who knows the process, but I'd remind everyone that they seemed perfectly logical to the guys who did them, simply because they didn't know any better.

Something everyone who engages in this activity needs to understand is that it's potentially dangerous, and yes, you CAN get hurt. Unfortunately, many of the injuries I've testified on, came from what seemed perfectly reasonable to the handloder at the time, because they had bad information or made dangerous assumptions like the OP has here. Unlike the OP, they injured themselves, and weren't trying to promote their "methods" to others. If you manage to hurt yourself through your own stupidity, that's on you. But injuring someone else who happens to follow the bad advice you put out, that's a whole 'nother ball game.

As I've already said, you need to be extremely cautious about where you get your information from, and cross check that info with other sources. In ANY of the reloading manuals from any of the major component makers, you'll find dire warnings against trying to identify powders by appearance. As for identifying them by smell, I can assure that that idea was simply too ridiculous for any of us to even consider including a warning about. Perhaps we should have. In the meantime, dig a bit deeper before you take "advice" of this sort. The more you know about the topic, I can assure you, the more you'll understand the folly of this entire thread.
 
What am I missing here? Why is everyone so up in arms about this issue?

OP is stating that he finds a factory round that shoots well in a firearm he owns.

To attempt to replicate the round he starts with the same bullet and shell.

Then he deconstructs a factory load and measures the powder charge by weight.

He then attempts to determine the powder used by sight and possibly smell.

By looking up the loading data for possible matches he can exclude powders that would not fall within that weight range.

The powders that do look similar and could fall within that weight range for that shell and bullet combination can then be loaded using standard workups for pressure.

In the past, he has found combinations that meet or exceed the factory rounds.

I and many others have done this in the past to attempt to replicate factory ammo. The Federal Gold Metal Match (FGMM) 168 grain .308 round would be a perfect example of a round many attempt to replicate.

I haven't seen yet where he suggests mixing powders and blindly throwing a comparable charge weight into a case and firing it.
 
No, but he does state that proprietary powders don't truly exist, and that "proprietary blends" refers to mixing portions of existing cannister grade powders. Doesn't happen, and this is not what a proprietary blend is.

How about trying to duplicate loads that use OBP715, K503, OBP846#11 or WC-750? I've used all of them recently, and there's not a one of them that is available on the commercial market. They all look somewhat similar to existing cannister grade powders, but are most definately different. In some cases they may have some data overlap, in others, they won't. Point is, the OP doesn't seem to understand or be willing to acknowledge the difference.
 
my wifes 7-08 won't shoot a thing I put thru it except Nosler Custom. They're down the street, I know guys who work there and they told me they use non commercial blends.
There is no way you can match them.
 
It's not that the OP asked anyone to do anything dangerous.

In fact, he's stated several times that you should use safe loading practices and published load data.

However, Kevin's concerns are well founded.

Disseminating bad information and false assumptions about mixing, blends, canister-grade powders, identification by sight and smell, etc... will get someone hurt down the road.

Richard--yes he did--READ IT AGAIN. That is what all of this has been about. I am afraid you missed the whole point.

Just a sample of the lunacy:

"But all "proprietary" means is they've either bought an off lot of powder or they have blended two different lots of the same powder, which will not be terribly unlike cannister grade stuff.

Where is the logic in getting a powder maker to come up with some sort of "magic" stuff? It wouldn't be cost effective... just not good business.

Just hoping to dispel the myth about "proprietary" powders, because that's really what it is--a myth."
 
Kevin and Boss...

What if the proprietary powders were the norm (rather than the exception)? For the sake of debate, let's give you guys that much...

Will one or both of you construct for the readers--and from the view count it looks like there are a lot of them--a remotely plausible scenario that ends in someone getting hurt because of what I've written here?

Please be articulate and concise. :)

To be clear it is Sheer Lunacy, Madness, Insanity, to try and identify a smokeless powder pulled from a commercially loaded round by sight, smell or taste because it cannot be done period.

Reasons why this is a life threatening proposition have been given already. You can only die once.
 
I asked for a scenario... just make one up! I'm curious to know how you envision this happening...

Perhaps others are curious as well...
 
Dan, do you realize that one of the posters that didn't see what was wrong with your thread is a very ambitious , sharp young man that is 13 years old? He is an avid hand loader with limited first hand experience at this age. Are you ok with instructing him to follow your suggestions? Can you insure there is no danger for this type of reader?

This is what bothers me about any uncertainty in hand loading and especially with powders. Today many never even open a manual. They read it all on the net.

Jeff
 
Broz... do you believe that barnesuser28 would explode his rifle and risk killing himself because he read my thread, misunderstood it, pulled a factory shell apart, guessed at the powder type, and without consulting a loading manual or applying any modicum of common sense, he loads up the full charge of the suspected powder and explodes his rifle?

Wouldn't it be MUCH more likely for a guy to see some load data one of you folks mentioned here... say, for RL17... and WHOOPS!... he thought you wrote RL7... and BLAMMO! You could get someone killed, right? Or maybe you were sharing some load data for your 30-06, and someone thought you meant it for a .308? See how dangerous this can be?

Where would it end? Must we assume that everyone is a moron? If so, then perhaps having a handloading section here is simply too risky... right?

Here's the thing guys... if someone is foolish enough to respond to what I've written in the way that some of you are suggesting, how could you trust such a person to handload at all? I mean, seriously... if there is anyone out there stupid enough to guess at a powder type from a factory shell, then just arbitrarily load that amount of canister powder from off his shelf--without once checking a loading manual--how do you think you're going to save him by lambasting me here?

What ever Dan, I guess we just don't think alike. You miss my point and I think you are flirting with a potential hazard. I made an attempt to explain and you come back with smart *** remarks and names. I should have kept quiet. There are some very well versed people with a ton of real knowledge that tried to explain to you. But you refuse to listen.
Good luck and be safe.

I don't think I called you a name... if you took my response that way, I'm sorry... it wasn't meant that way.

But.I do think that the 13 year old who read and posted, and understood my original point actually bodes against the idea that young folks can't understand these issues.

You're a decent guy, Broz... I'm sorry I offended you.

Sometimes trying to prove oneself right is not worth the collateral damage... :( ...again, I'm sorry for how I came off...
 
Dan -

I don't have a problem with what you're asking people to do. i.e....ultimately refer to published load data.

Where the danger lies is that you put forth some very wrong ideas about factory ammo; proprietary vs cannister powders; and an individual's ability to identify powders by sight and smell.

The experts weighed in vehemently on all that and you have yet to admit that you were completely wrong or out of line to promote those bad and incorrect ideas.

You can debate all you want whether the "proprietary blends" are better than cannister grade. But, they are different and you can't tell what's what by weight, feel, sight, taste, or smell.

It's all great if a 13yo indicates he understands safe loading procedures, so long as he always refers to published load data and follows safe loading procedures.

But the minute that he gets the notion he can identify powders and understand properties by sight or smell, then somebody's going to get hurt.

How 'bout it Riley?
Yes, or No... Do you agree with Dan that you can reasonably identify powders by weight, sight, and/or smell?
