Or is it nobler to shoot the 223 as a Bee, could THAT be the answer?

Hunting coyotes, rock chucks and prairie dogs usually means a good stiff load when you're shooting the popular 223. When hunting these varmints, you are usually well away from areas where noise is of much concern, other than maybe to the ears of your hunting partner. As we 223 shooters are aware, the 223 performs admirably out to approximately 300 yards with a whack of good stopping power.

However, every now and then it would be nice to have a .218 Bee or a Hornet. I've shot fox with the 223 loaded with 50 or 52gr. bullets and it's usually the same old story; the hide gets blasted. Quite often, while hunting gophers (ground squirrels), I'm shooting amongst cattle and sometimes right into farmers' yards. Unless your landowner/host is an accomplished varminter himself, the blasting of a 223 in the yard can be unnerving, especially if they are expecting only a rimfire. Besides, pursuing gophers with a fully-loaded 223 at ten feet has always seemed over-kill to me, although my shooting partner, Barry, would disagree.

All this got me to thinking, "Why not work up a reduced-charge load for the 223?" As reloaders we have this wonderful option. The idea here is to reach velocities of approximately 3000 fps, with maximum expansion to keep ricochets and noise to a minimum. Oh yeah, cost would be reduced with the smaller amounts of powder used. Less powder also means more shooting before your barrel overheats. A real plus when there's a varmint charge!

I chose to use the James Calhoon 37gr. Dbl HP bullet (designed for the fancy .22 Cooper rifles) which work around 2300 fps (the James Calhoon 37gr. Dbl HP bullet will actually stay together up to around 4000 fps). If I want more weight in windy conditions, I use a James Calhoon 42gr. Dbl HP bullet. I started out using 296 Ball powder, but I was not impressed with the grouping and noted the odd hangfire at reduced loads. I came to the conclusion that the preferred type of powder for a reduced load in a 223 would have to be a flake powder. Ball and even stick powders are much too dense to be considered for reduced loads in the 223. With the case only half charged or so, a bulky fluffy powder guarantees ignition to be consistent.

Further tests did prove IMR 800X to be the best reduced-charge powder for the 223/37gr. Dbl HP combination. The 800X works well right down to three grains of powder and does not require a wad to maintain good ignition. Two grains of powder will cause the bullet to stick to the barrel. The three to four grain load also makes a good "basement" load for a contender, basically duplicating a .22 rimfire load. No wadding is required. Other pistol/shotgun powders can be used as long as it is a flake powder, but 800X works well, right from a minimum of three grains up to a twelve grain maximum.

To us rifle shooters, 800X is peculiar-looking stuff. It has to be the largest-looking flake (around 3/32" in diameter) powder I've seen. I can't say it meters real well, well enough though, but it sure bulks up. For example, with my measure set of eleven grains of 800X, the measure threw fifteen and a half grains of 2015BR (short stick rifle powder). That comes out to 41% more bulk.

When using 800X, I've found the powder to leave quite a bit of "Muzzle Mud." That's the black cake stuff you get on the crown after fifty or sixty shots. I'm presuming that's a graphite or carbon buildup from the powder. I've used Unique and have had virtually no "Muzzle Mud," but the barrel fouls twice as fast as with the "dirtier" 800X. Maybe overly clean burning powder is not necessary, or even desirable. Powders that leave a good deposit of graphite should, and appear to, dry lube the barrel and reduce fouling. I'd like to hear from powder makers out there on this theory.

As most of you know, graphite is a super slippery black powder which is added to grease to improve performance under extreme pressure. Isn't that what we're after; improving performance under extreme pressure? How about that fella from Silver Eagle Machine in Glendale, Arizona, who makes the graphite wax wads? I'd like to see some test results. Groups before and after the wads; how many shots before the groups go. The graphite to use for bullet application should be "colloidal graphite" which is made electrically and is the purist form of graphite. It looks like tiny ball bearings (under a microscope) and does not break down into carbon as does regular graphite under high heat and pressure.

Anyway, good accuracy is achieved across the loading range using 800X, with exceptional groups as loads reach maximum (under 1/2") - groups as good as your regular 50/52gr. loads can be expected. With eleven grains or more of 800X and the 37gr. Dbl HP, elevation at 100 yards is roughly 1/2" low from your normal 223 load. Windage should hold. As expected, this light load will be pushed around by the wind, about twice as much as the 50gr. standard load. I usually limit my shots to 100 yards in strong winds. On a calm day, 150 yards is not difficult.

For distinguishing, your reduced loads, a dab with a blue marker (blue for cool) on the primer makes them easy to pick out from your regular 223 loads. Barry uses his crayon.

If you load your cases one at a time into the chamber, all you have to do is make a choice. For a magazine gun, I keep the mag loaded with regular loads, minus one or two. This gives me the option of feeding a regular round from the mag or inserting a reduced load into the mag.

My favorite reduced load for my 223's is eleven and a half grains of 800X behind a 37gr. Dbl HP. This load produces recoil similar to the .17 Reminegton, has a report like a Hornet, and hitting power that surprised even Barry. Barry says "I DO like that load!"

I prefer a NECK sizer only. The Forester/Bonanza seater is very good.

The 221 Fireball and 222 Remington also work well using reduced-charged loads. For reduced loads in the 222 Remington, reduce maximum load by one grain of powder from the 223. For reduced loads in the 221 Fireball, reduce maximum load by two grains of powder from the 223.

Shooting reduced load 223's makes two rifles out of one. Instead of bringing along two rifles, I now just bring another bucket of ammo. I certainly have no need for a rimfire anymore, especially considering the accuracy, versatility, cooler shooting, and convenience of a reduced load 223.
