Probably the reason there isn't any H4350. Marketing a new powder and meeting new demand. Made by same Corp.

Oops, my bad you're correct.

las,

With my present batches of H4350 and IMR4451, the 4451 is slightly faster-burning, but not much. In my 7x57 I use 46.0 grains of H4350 with 160-grain bullets, and with 4451 get the same results with 45.5. Have had similar results in other rounds, so they're pretty close--close enough that some lots may get exactly the same results, or H4350 might be slightly faster burning than 4451.

Is the 4451 powder measure friendly?

Thanks,

Jeff

Gun Powder and explosives can only be transported in a limited number of ships that are licensed for the task to be as unspecific as I can.
There is potential conflict in the world.
These ships need to remain unknown.

That is all anyone needs to know.

My advice is to treat powder like your booze and stock more than you need.

Seems to be some H4350 becoming more available. I bought 2lb in Sportsman's warehouse Loveland, Co. Have seen some in other stores too.

Alright, John. How about a new list of your favorite 4451 recipes for the old 7x57. Inquiring minds, you know.

By the way, I've been goofing around with Hunter and 160-grain Partitions, but have some data for Big Game in loads from 100- to 175-grains. I'm planning to work up some loads using 154-gr SP at around 2600+/- to use on pigs and our dinky deer. The Ramshot powders seem to be more available than just about anything else right now.

Jeff,

4451 is just as measure-friendly as H4350. It's another short-cut extruded powder.

Mike,

As I've pointed out before, 7x57's vary considerably in how much powder they'll take, due to variations in throat length. Mine custom rifle was chambered with a PT&G "target" reamer with a short throat, so doesn't need as much powder to get the same velocities as most other 7x57's. I've only tried 4451 with bullets in the 160-grain range, mostly because they all shoot to the same POI in this rifle, and 45.5 grains of 4451 gets right around 2700 fps with most bullets, from a 21-inch barrel.

Thanks, John. I'm aware of your caution about the differences in throats, etc., but I was just wondering of there was some correspondence between 4451 and H4350. From your H4350 recipes in "Gack" it looks like there's about a half grain.

Mike,

As I've mentioned in other posts (and in various articles and books) there is no firm relationship between different powders of very similar burn-rates, because any powder will vary slightly in burn-rate from lot to lot. IMR4350 and H4350 are a good example. When H4350 appeared, many handloaders firmly stated it was slower burning than IMR4350, and much of Hodgdon's data backed that up.

But one of the interesting side-effects of companies posting their latest data on the Internet is a clearer look at how powder lots vary. Since it was first introduced, the latest data for H4350 has been both "slower"
and "faster" than the latest data for IMR4350. This isn't a mystery, just the way powders vary over time.

Another little piece of evidence came with my first two lots of IMR4451. The first was a couple pounds sent to me by Hodgdon to try out. I liked it so well I ordered an 8-pound jug off the Internet--and discovered its burn-rate was slightly faster, not surprising since it was over a year after my first sample showed up, and the jug was a new lot. After a little more testing, I eventually mixed what remained of my first two pounds in with the jug--and not surprisingly, the mixed IMR4451 was a little slower than the jug's initial burn-rate.

What I understand from powder companies is that's exactly how new batches of powder are mixed to result in a reasonably consistent burn-rate for handloading powders. They keep some slower and faster lots of that powder on hand, so they can "adjust" the burn-rate of a new manufacturing lot.

On the other hand, many ammo companies use unmixed powders, adjusting the charge according to how the new lot burns. But they're usually boxcar loads of powder, and have pressure-testing equipment.

When I see certain powders that I want that's not commonly found, I usually buy it and try not to look at the price tag. There's a fellow that shows up at certain gun shows that has many of these "unattainable" powders. So I try to have a couple $100 set aside for powder purchases come gun show time.

I had difficulty getting 215 primers for a while. A friend picked some up for me at the Tulsa gun show. Now I see it fairly often. Go figure.

My advice is to be prepared when you attend gun shows, the gun shows brings lots of vendors. Sometimes internet searches work too.

IMR 4350 is also hard to find, searched several stores in my area and finally found a pound at the area's largest gun show. It was the last that any of the reloading vendors had.

How do people just make stuff up and then write about it with such authority? I mean, honestly.

As a matter of facts, there are none: This is totally untrue. To anyone in shipping it's just absurd.

Moving this type of cargo is a matter of commercial normality. If there are shortages of powder where you live, its just supply and demand. Containers of powder and ammunition, both military and sporting, are shipped around the world as a matter of course on standard container ships. They have only to observe the appropriate IMO standards for sea transport that anyone shipping hairspray or fishmeal does. There are restrictions only in the separation of hazardous cargo, where it can be stowed on the ship, and with some classes, in the timing at when it can be loaded or discharged. None of which impedes its transport around the globe.

I know some about the shipping of consumer-grade fireworks, directly from China, and some of the hoops involved. From what I could tell, regulations weren't particularly strict, and there was nothing secretive about them. They were shipped in shipping containers on a shipping vessel, and then had to be transported in specific ways once they got to the US. It didn't take much time from being notified of the shipment to receiving it on a trailer. Nothing particularly clandestine about the process, but fireworks have not been military-grade for some centuries now.

To be honest even the shipping of actual currency isn't especially secretive. (Probably so as to not draw attention.) Eighteen tons worth of twenty dollar bills...

There are things more hazardous than ADI's powders being shipped as a matter of course.

The most secretive product (apart from Naval Intelligence work in a former role) shipped around the Pacific was in fact - concrete. All involved were sworn to secrecy. It become plain to me that we were shipping thousands of tons of concrete each month to Mururoa Atoll on behalf of the French government. They must have concreted that whole island after they stopped nuclear bomb testing.

CarlsenHighway,

Maybe you can confirm (or dis-confirm) what I was told by one of higher-ups in one of the corporations involved in the buying, selling and hence transporting of powders around the world.

The recent component "shortage" here in the U.S. was caused not by lower supplies of reloading components, but by high demand due to the possibility of Obama declaring who-knows-what about the purchase of guns and ammo. But demand was so high, my contact said, that the authorities in Auckland grew alarmed at so many more ships full of powder passing through their port on the way to the U.S., and ruled that no more than one powder-container ship could be in the harbor at one time. This created a bottleneck between Australia and the U.S. which made the shortage worse.

Now, maybe he didn't know what he was talking about, but since he's been employed by a major powder company for many years I don't know why he'd be confused. Since you're there, maybe you could find out something about this possibility.
