One consistent question from
Handloader readers goes something like this: Why do new powders keep popping up like
spring mushrooms, when the old powders work just fine?
This is a recent phenomenon. During
the first couple decades of my handloading career, new powders were rare. Hodgdon was
still selling military-surplus powder, and DuPont (now IMR) and Hercules (now Alliant)
sold the same powders they’d been selling since before World War II. Even when
somebody introduced a new powder, they took their own sweet time. DuPont developed
IMR-7828 in the early 1960s for 7mm Remington Magnum factory loads but took well over a
decade to start selling it to the public. They didn’t introduce IMR-4831 until
Hodgdon finally ran out of its old military H-4831 in the early 1970s and had to get new
4831 produced.
Because of this relative lack of
powders, I eventually settled on maybe half a dozen for all my handloading, including
handguns, shotguns and rifles. They all went bang and punctured targets and game. These
included H-4831, IMR-4350, IMR-4895, Red Dot, Blue Dot and 2400, which pretty much covered
it. They still pretty much could.
So why do dozens of powders now
inhabit my loading room, most of which I’ve not even tried? Partly because
manufacturers send them to me, and partly because many work better than the old standbys.
Let’s list what smokeless
powder should do, no matter the firearm. It should obtain optimum velocity, whether we’re
hunting in 80-degree heat or near-zero cold. It should burn cleanly, so accuracy and
patterns remain consistent, and we don’t have to spend hours pushing sludge from our
barrels. It should be able to do a good job in several cartridges and flow reasonably well
through a powder measure, saving us bench-time.
Those elements divide many of the
old standbys from newer powders - and have even changed some of the old standbys. I bought
the last two pounds of surplus H-4831 in eastern Montana in a tank-town hardware store in
1973, if memory serves, for $2.25 a can. The powder worked, but its granules were nearly
the size of fence posts - or at least they seemed that way in a powder measure, or when
seating a 130-grain bullet in a .270 Winchester case. Often the same load shot to a
different point of impact during a November mule deer hunt than when sighted in on a
September morning. A few years later, I bought my first chronograph and found out why:
Those .270 loads lost about 150 fps between 70 degrees and zero.
Aside from burning rate, today’s H-4831
Short Cut is an entirely different powder. Its granules are indeed short, so with care it
meters acceptably, and you don’t have to sit on the press handle to seat 130-grain
.270 bullets. It burns cleaner than the old stuff and won’t lose 10 fps when the
temperature drops to zero.

Good changes have been made in other
“old” powders. New Unique burns much cleaner than the old, and the latest
version of Reloder 15 is about as temperature-steady as the Hodgdon Extremes.
Some new powders are genuine
breakthroughs. The Ramshot line of ball powders is most impressive. Ball powders are
cheaper to manufacture and flow nicely through a measure, the reason a lot of factory
ammunition is loaded with ball. Handloaders use ball powders for the same reasons but
generally regard them as dirty-burning and temperature-sensitive.
The Ramshot powders are
clean-burning. I’ve been using 26 grains of Ramshot TAC and a 50-grain Ballistic Tip
as my standard .223 Remington load for three years now. This summer I ran almost 450
rounds through my heavy-barreled Remington Model 700 during a two-day prairie dog shoot
without cleaning the barrel. Then I went home and shot a five-shot, .56-inch group over
the benchrest, which is how cartridges produced on my RCBS Piggyback machine always group.
Then I cleaned the barrel, taking half a dozen patches of Hoppe’s to get rid of the
powder fouling.
With the older ball powder I used to
load, bullets would have started spraying all over the landscape within 100 rounds, and
deep excavation would be required to remove the soot. Like the “new” Reloder 15,
the Ramshot powders are nearly as temperature-stable as the Hodgdon Extremes, the reason
TAC, Big Game and Magnum are now the powders of choice for a dozen hunting loads.
I still use quite a lot of IMR-4895
and IMR-4350, because they’re both accurate and flexible. But IMR-4895 velocities
still vary considerably with temperature, and IMR-4350 still has granules like fence
posts. Quite often TAC or RL-15 are tried in situations where IMR cans used to come off
the shelf, and H-4350 and Ramshot Big Game often substitute for IMR-4350.
Sometimes there do seem to be too
many powders - until you try something better.
Norma 205 may have disappeared, but
other Norma components are still available. I reported on its Oryx bullet in the last
issue and will be reporting on its powders in the future, but am most impressed by Norma
brass, which always gets high ratings among the target-shooting crowd. Its weight, neck
thickness, primer pocket and flash-hole dimensions are always very consistent, and cases
normally arrive without the amoeba-shaped case mouths typical of American bulk brass.
Normally you can just chamfer lightly and load ‘em up. I did just that with 60 rounds
of .30-06 brass that went to Africa this spring, loading 180-grain Nosler Partitions over
59 grains of Reloder 19. The ammunition grouped consistently under an inch, even in the
generous factory chamber of my Remington Model 700.
Norma brass comes in all the usual
suspects, from .223 Remington to .338 Winchester Magnum, but is also available in some
older cartridges that are starting to live again, such as the 9.3x62 Mauser and .416
Rigby. I’ve used it in both cartridges, again with excellent results. Norma cases
cost more than most, which generally happens when you go first-class, but 100 9.3x62 cases
will last me a long time.
Norma products are available through several
major distributors in the U.S. For a catalog contact MidwayUSA, 1-800-243-3220, or Graf
