02/11/2024 – The following is the article that was scheduled for this past week. I could not get it done. I still can’t get it done, but I believe there is enough useful handload information to not just toss it.
The theme was putting odds and ends components to use, rather than have them waste away on a shelf. Then the theme became putting rifles that, by intent, would see infrequent use, to greater use. Then there was a momentary diatribe regarding component manufacturers forcing product obsolescence.
Then it became an article about me trying to decide if it is time to sell the house and property, put the proceeds into trust for my kids and grand kids, and move into a small cabin on one of Maine’s more remote fishing lakes with my gear, power tools and guns.
I finally solved the mental log jam by buying a motorcycle and planning a long trip. Yes, the mind works in mysterious ways. Some more so than others. So let’s get this one put away so I can get onto other things.
The Larch
If you are a longer term handloader, you probably have an inventory of left over bullet and powder inventory. Often, an accumulation that results from selling associated firearms, marketing engineered obsolescence or disappointing, substandard performance on initial use.
Not that I am frugal, but I almost always find use for the left overs. After all, they don’t have a “Best if used by” or expiration date. A couple of boxes of 0.243″ Speer bullets from ’67 or ’68 would still work, great, even if they are bit… green.
Metal cans of smokeless powder, sealed up tight and in temperature/humidity controlled storage, stand tall, alongside those plastic powder containers with first generation graphics.
Besides, it’s fun. Sort of like poking through leftovers in the refrigerator and finding that bacon and spinach actually do go well with melted sharp cheddar, on a white flour tortilla.
Putting a 375 Ruger to work, or creating purpose
A Ruger M77 African in 375 Ruger is a wonderful walnut and blued steel classic rifle. Compared to a 375 H&H, the M77 is two and one half pounds lighter than a typical express rifle. The African has a much shorter bolt throw and the 375 Ruger generates 100 fps to 150 fps greater muzzle velocity. It is an easy to carry, dispatcher of big and dangerous game.
Firearms last a long time and, sometimes, even special ones fall out of use. In my little piece of reality, future hunts for brown bear, or hunts in Africa, would be incredibly expensive and rare in occurrence… let’s call that no chance at all.
At my age, there is little thrill in trail blazing miles into the woods, for the sole purpose of killing a large animal I won’t eat. These days, I like to be in casual hiking distance from the truck so I can, at my discretion, get back, run the heater, crack open the thermos… and maybe take a little snooze in advance of the afternoon’s activities.
Subsequently, if I am not going to pop a cape buffalo or Alaskan moose, and I want to shoot the 375 Ruger because I am attached to the rifle, I need ammunition I can shoot on a long range day.
Exploration into inventory…
The eleven bullets pictured are all 0.375″ caliber, and purchased within the past five years. They range in weight from 200 grains to 350 grains, a couple are for the 375 Winchester or modern bore size 38-55 Winchester. The rest are for magnum 375 cartridges. Status? As they appear left to right above, and top to bottom on the table:

*Woodleigh Weldcore PP | 350 | No | No | No |
*The Woodleigh factory was out of commission after a fire. They are recovering and have resumed operations, however, the 0.375″ 350 grain is not in their current listings. Great bullets. Hope they make their way back into U.S. supply. |
What’s my point? You’re always asking that question. Okay. Eight of eleven bullets, for one reason or another, are out of production. Most have no replacement in form, construction or weight. Others have been replaced with “New!” bullets that are 2x and 3x the price of the original with attributes that don’t mean jack to me… or anyone else.
So I split my remnant inventory into two categories. The first is the sacred, irreplaceable, no longer in production bullets, with associated developed load data. Even if I don’t use them, I may load them for a friend. Yes, I actually do have friends. The second category of remnant bullet is comprised of “I can’t remember why I bought them, or why I stopped using them” bullets, that probably go with a rifle I sold thirty years ago.
This one is for me. That one is for you.
When planning a range excursion with a magnum rifle, I assemble two levels of handloads. The first are soft loads I can shoot all day at the range. While diminished from full tilt loads, they could also be used by anyone with the inclination for hunting deer, black bear and hogs.
The second level are “Good grief” loads, which I save for anyone at the range who pesters me into letting them shoot my rifle. It is not that I am mean, I just want them to get the full magnum experience. What can I say, I am a giving kind of guy. None of these appear on the load data table that follows.
The four selected at the moment
All were checked with the subject rifle and a COL gauge. Each bullet cleared rifling leade in assembled cartridge form, and cannelures lined up with case mouths.
Bullet | Type | Weight Grains |

*Sierra Pro-Hunter | FNSP | 200 | 0.840 | 3.115 | 2,200 |
Hornady SP | SP | 225 | 1.125 | 3.280 | 3100 |
Speer Hot-Cor | SP | 235 | 1.058 | 3.250 | 3,000 |
*Barnes Original | FNSP | 255 | 1.066 | 3.130 | 2,200 |
*Intended for 375 Winchester |
The manufacturers’ maximum fps is important. If pushed to hard, close in and before velocity has bled off, they will fragment or shed jackets and will damage meat. By the same token, driven too far below design low end velocity, they won’t properly and will over penetrate.
In the low velocity range, the attempt is to approach 375 Winchester performance. At the higher velocity performance, the objective was to bring about proper expansion without reaching magnum level loads and losing the benefits of lighter recoil and report.
Vintage bullets? Gotta have vintage powder…
In addition to remnant bullets, there is remnant powder, also the product of discontinued cartridge use, change to different types, product discontinuation etc. Yes, those metal cans are at least four decades old. The Alliant 2400 is at least a couple of decades old and the Trail Boss is maybe ten years old and now out of production.
Doesn’t powder grow old and… wilt? Well, in the ’80s, powder companies were still selling military surplus powder from World Was II as repackaged commercial product. Typically, smokeless powder stores well, even in extreme dry cold, however, high temperatures and high humidity cause smokeless powder to deteriorate and lose potency.
Powder should also not be subjected to environmental contaminates; oils, solvents, water, etc. I store my powder at 25% humidity, within a temperature range of 60°F to 70°F. It is kept away from contaminates and it is used FIFO with only one container of any type open at any time. The powder containers pictured above have fallen out of use.

I would Maine deer hunt with anything on the table, however, even at moderate velocity the 375 Ruger puts up some substantial kinetic energy. They would be perfectly fine for heavy bodied, thin skinned game, if shooting distance weren’t stretched.
I was surprised by the accuracy… precision of most of these loads. I got to use up bullets and powder that would have sat on the shelf, I got to play with the 375 Ruger African, and I got to spend a few days outdoors. Maybe nothing more than fun, but that in itself is enough of a reason for the project.
More fun than starting campfires! Thanks
Joe, I feel your pain. I’ve been reloading since 1967 and have the same problem, I too have a 375 Ruger, a walnut stocked, open sighted Mossberg Patriot. When I bought the rifle, had planned to use the Hornady 225 Spire point more or less exclusively, since the woods are full of Remington 30-06 autoloaders shooting 220 grain Corelokts. As soon as my rifle arrived, Hornady ceased production of the 225 Spirepoints. All last year I developed loads for rifle calibers using mostly cast bullets and TrailBoss. These included the usual levergun favorites such as 47-70, 450 Marlin, 444, 375 Winchester and not to mention 308, 358, and 325 WSM. I’m considering using light weight varmint bullets for 250 Savage, 6.5’s, and 7mm’s with a case full of TrailBoss. Since I’ve been collecting brass for the last 50 years, I thinned the herd by taking everything I did not currently have a rifle or handgun for to the scrap yard. No more saving brass for “just in case”. Also no more loading for others, unless they bring ALL of the components(primers especially. I could go on and on, but you get the point. Hang in there , Buddy! Bob!
That may be the way to go. I am generally not a hoarder, but I can’t seem to part with brass and dies. I always think I will need them. Have not owned a 25-20 WCF or a 450/400 3″ NE for some time, but what if… Yes, I think you have that right.
