The Powder Room - CAS reloading / Re: Burn Rates of Smokeless powders
« Last post by Trailrider on Today at 11:13:16 AM »
BY ALL MEANS, USE THE RECOMMENDED LISTINGS IN THE LOADING HANDBOOKS! Over the sixty-plus years since I started handloading, I have found that if one seems to get close to or right on the maximum or minimum loads listed, it may be prudent to look at a different powder. Minimum loads in particular can present problems. It takes 5,000 - 7,000 psi (NOT CUP) to get smokeless powder burning stably. The listings in the manuals are determined under certain conditions which may not obtain in your particular gun, with a softer or harder cast bullet, or with too light a crimp. For example, if you want a reduced load in your .45LC, with bullets much lighter than 250 grains, rather than using Unique, you may be better served in going to W231/HP38 (same powder, different brand). If you have 2400, I definitely would not go with reduced loads, but with a faster powder, such as Unique.  In large magnum rifle cartridges, reduced loads of slow-burning powders can lead to real trouble! For example, DO NOT reduce loads for H4831 and others when trying to make a .338 Magnum feel like a light .30-06! Look at a faster powder such as IMR4350. These are generalizations, but as I shouted at the beginning, USE THE BLOODY MANUALS!

If one of the reproduction makers would build and chamber one of those I'd have to buy one. (smile)

PS: Same for a repro Henry chambered for the Russian.

Let there be light!!  Yes!!  Flip the switch.  No !!  Wait!!  Having the knowledge of specific pressure curves can be highly evocative.  Er, of what he asks.  Well Now.

As pointed out by Monsieur Austin, I can in fact, drop a Small Block V8 into my Mini Cooper.  I won't be able to drive it, but I can get it in there (Actually been done) and that knowledge becomes totally useless trivia.  Is useless trivia.  Actually.

When, in my sordid, uneducated, heathen past, found myself in need to replenish my supplies is explosives (actually combustibles) for (combust really fast) furthering my penchant for playing with destructive devices and such, I found it best to simply peruse my available re-loading manuals to find a propellant I might like.  Sometimes that endeavor led me to some totally inappropriate selections anyway.  I mean sure, you can dump "X" amount of sifted Elk Snot into Y size cartridge case.  But what if you wind up with Kapouf rather than a satisfying BUUMBA??  Been know to happen.

There are other mitigating factors to consider as well.  Like a real serious FUN FACTOR!!  The kind of fun factor you get by ripping off a half dozen rounds full of 2F APP at an indoor range before they can get to ya!!  Superior fun you betcha.  All that satisfying coughing and sneezing from the stuck up snob glitterati is just marvelous.  And there is the screaming and tearing eyes, well you get the picture, as you calmly reload another half dozen .45 sized cartridges into yer hand howetzer.  And the poor schmuck at the counter is taking a dump in his (or her's) Post Toasties trying to stop you from setting off another batch.  Great FUN.

Oh, Where was I.  I know I had a point to all of this when I started, but be dam'd if I can remember what I wanted to say.  Obviously something of so little import I immediately forgot what it twer as it twer.  Oh well.  You've gotten this far so there is no going back.  Nanny Nanny Poo Poo.

Oh Wait!!  I remember!!

TRAIL BOSS SUX.

Remember, People still be Hazardous to Yer Health!!

Greetings all.

Today was spent on a plane. I currently can’t reveal where I am, but I’ll let you know where it was in a few days.

Anyway, i have to board another plane. Y’all take care.

Hmmm

lots of esoteric air traffic lately.

Ah My Good Bunk

You and I are not only :"like minded" and  on the same page but are in the same choir.

Howver, like Bryan's efforts, this discussion is geared towards the advanced amatuer.

I do not have many pressure curves to work from ( thank you Bryan for posting your results!)
and there is occasionally  the issue of "too fast a pistol powder" in "too large a cartridge case"

One useful datum example is comparing Trail Boss and Unique.

Trail Boss ( as most of us know) was deliberately made as a fluffy powder to easily use in
large cases and reduce the risk of accidental double charges and there are a number of loads in
the manuals for it.

Some people came up with the erroneous idea that Trail boss is good for "older pistols".

In fact, Trail Boss has a faster burn rate and steeper pressure curve than Unique, making it ill suited
for weak designs or "older pistols",  Even tho the loading manuals show valid loads for both.

Thus both the "burn rate" and "pressure curve" data become useful

Of course one could always stuff a case full of APP but the  indoor ranges frown on it.

Then on a pratical note, since powder availability is "iffy" , I take my list of burn rates with me,
along with two of my favorite loading manuals when I wander down to the powder store.

There, I see what they actually have on hand, and I am using burn rates to determine which powders might be more
appropriate for short barreled pistols vs long barreled rifles, then go to the manual to determine appropriate published
loads and load data.

Often I find that what they have does not match what I want to do, thus saving time, money and grief.

On a esoteric philosophical note I am fascinated by comparing the burn rates and pressure curves
on several oldy moldy smokeless powders that a number of experts are using to good effect in
trapdoor, rolling block, and falling block rifles. One powder they like (I forget which) actually has a burn rate
and pressure curve datum that (according to their lab tests) closely match the original Dupont Best Rifle Powder.
