    Notes:

    1. IN the evaluation of the 223, I came further to the conclusion of the versatility of the 223 in the use of training new shooters, and for a very versatile varmint caliber.
    2. Essentially the 223 can be loaded to the specs of a 22 Long rifle, a 218 Bee, a 221 Fireball, a 222 Remington, a 22 Hornet, and a 22 Win Mag., while allowing the shooter to be able to pick the type of bullet that he prefers.
    3. Bullets were limited to use of 35 grains to 55 grains. Heavier bullets will not serve any purpose unless a 223 is to be used for deer hunting. I do not believe that their would be a significant difference in the use of a 55 grain bullet vs a 60 grain bullet.
    4. The recoil on the lighter loads using 4 to 6 grains of powder had minimal recoil if any at all. These would be ideal for young shooters being trained.
    5. Noise level on the lighter loads ( 4 to 6 grains) were on par with a rim fire. An increase in noise level was very noticeable above 7 grains, but still very acceptable. ( No sounding like a rim fire any more)

    Noted Observations:

    1. It was noted but not considered part of the testing, with a tree used as a back stop for some of the testing, that all bullets ( 45 to 55 grains)penetrated thru the tree at a distance of 20 yds.
    2. The diameter of the tree was measured at 5 inches.
    3. The 40 grain Vmax loads failed to penetrate the tree at loads above 10 grs, above 2771 fps. However at 10 grains and less, the bullets penetrated thru the tree and did a large amount of damage ( like turning the wood into tooth picks) on the exit side of the tree. The penetration stopped at the 5 grain load.


    Some of the Author’s Conclusions:

    1. I learned some significant items beyond the versatility of the 223 with the bullets tested, but focusing on its use in the field, got some ideas.
    2. A light rifle such as a Winchester Featherweight or Rugers Compact model with a 16.5 inch barrel or the Ultra Light with a 20 inch barrel would make a good combo with the use of Blue Dot.
    3. Since the powder is burned cleanly in the first 10 to 12 inches of barrel, the shorter barrels are not handicappiing velocity in the lighter shorter rifles.
    4. The penetration of the 40 grain Vmax into the tree did make me ponder the use of those plastic tip varmint rounds as potential loads for small deer for youth shooters. Just like my observations in the larger calibers, the plastic tipped bullet seem to do a lot more damage, at velocities under 2700 fps. The Vmax surprised me. This is a decision any shooter will have to test on his own and make their own decisions. I am just passing on that I saw potential merit in the application.
    5. Although one has to weigh out the potential of Plastic Tipped Varmint bullets on bigger game like deer and antelope, some of these loads in real life use, utilizing Barnes’s X bullets in 22 caliber I can recommend. They make a 45 grain, 50 grain and 53 grain bullet. The way I saw much better penetration and more damage in wood, at the lower range velocities, 2200 to 2700 fps, this would make a good deer load in many parts of the USA, and recoil is minimal.


    I did not test any bigger bullets as I feel that those tested would be represent the best potential with the powder. 60, 63, 64, 65 grain bullets and then the larger match bullets did not give what I considered useful velocity when I have shot them before with Blue Dot, in respect to their field design uses.

    Very cool, I helped work up some .223 loads using Bullseye and Unique I believe. We ended up getting 77 grain bullets to run subsonic velocities and they were very quiet through a suppressor.

    I'll have to check my notes, but I recall using very small charges (maybe 3 grs ?) of Red Dot in .223 Rem for creating .22 LR and .22 Mag type-performance loads for a single shot pistol. I didn't use Blue Dot, but I think it could be used similarly. Blue Dot would take a little more powder and probably generate higher velocities safely, but there is NO WAY that I would go as high as the experimenter you quoted. The peak pressures are probably WAY high. If it were me, I would've stopped at about 6 grs regardless of bullet weight and wouldn't use any bullet heavier than 55 grs. Since none of this is published data, you are completely on your own and I would strongly advise talking with a technician at Alliant before doing anything.

    Ive successfully loaded 55gr pulled m193 projctiles over alliant 2400 powder (using factory primed m193 brass) and had it cycling a standard 16" ar rifle.

    2400 is just a bit slower than bluedot, but meters better. Also, ive heard bludot can misbehave at higher pressures.

    I dont have the data in front of me at the moment.

    The safest powder to use with reduced loads is H4895 or Trail Boss, you can't double charge the case and it gives better loading density than pistol or shotgun powders.

    Can you elaborate?
    I thought Blue Dot was intended for magnum pistol (and shotgun) rather than rifle powder.
    How might it "misbehave at higher pressures"?

    Inquiring minds want to know...

    You're right, blue dot is a magnum pistol & shotgun powder, not a rifle powder.

    I have no first hand experience, but i have read before from one or two other reloaders, that at max charge levels, blue dot can occasionally spike in pressures unexpectedly, thus "misbehaving".

    I will google it some to see if i can find what i read before.

    Blue Dot is very temperature sensitive - if you are loading close to max. the pressures can spike rapidly as the temp. goes down. I used to use it for .357 and .41 Mag. until Alliant changed the formulation that Hercules used and issued a statement about it not being suitable for .41 Mag. It also produces a VERY hot flame and will erode forcing cones on revolvers rapidly if used with light fast bullets. I ruined a GP 100 forcing cone after using Blue Dot max loads for only 2 months. It looks like an oxy-acetylene cutting torch was applied to it. Speer listed that load as safe and then suddenly dropped it from the next reloading manual. I remember it was the loudest report I have ever heard from a .357 revolver and made a flame the size of a basketball when fired. There are plenty of other suitable powders on the market - I would skip Blue Dot.

    Here's my data (use at your own risk):

    223/5.56
    55gr FMJ-BT M193 style projectiles
    Lightly crimped with Lee factory crimp die
    2.25" OAL (seated to the crimping groove)
    15.5grs of Alliant 2400 is what I settled at (Quickload estimated 15.9grs to be the maximum charge)
    factory primed Federal XM193 brass
    I have notated ~2800fps, but I don't remember if I measured that, or if that was just Quickload's estimate...
    Cycled 100% in my assembled AR-15 (just a standard setup: 16" Anderson Chome lined 1-8" twist barrel, carbine gas, m16 carrier, carbine spring & buffer)

    Once again, I assume no responsibility for anyone using my reloading data. Use at your own risk.

    Blue Dot is very temperature sensitive - if you are loading close to max. the pressures can spike rapidly as the temp. goes down.

    Double base powders are more temperature sensitive than single base powders. And the "warmer" it gets the more the chamber pressure will increase and even spike.

    What is strange is Alliant's warning tells you to not use Blue Dot with the .357 and 125 grain bullets. But at Alliant's website they give load data for 110, 140, 158 and 170 grain bullets.

    That's true, however I believe there may be exceptions to that rule. When I was googling Blue Dot earlier, I came across more than one mention of Blue Dot having very erratic ignition in much colder weather. One person reported a standard deviation of over 200 when firing blue dot in freezing weather. This may have been the "misbehaving" I was remembering from before...

    I read about that too, and someone was saying that Blue Dot produces a very hot flame, and something about the flame that 125gr load data produces was quickly eroding forcing cones in revolvers. One user reported "ruining" a Ruger GP100's forcing cone from shooting 125gr Blue Dot loads over a period of 2 months. He said it appeared that someone took an Oxy-Aceteline torch to the forcing cone...

    Make of that what you will...

    Go figure, the Lyman 50 Addition has .357 125 grain bullet loads using blue dot. There are many posts about Blue Dot but Alliant doesn't explain the "why" of the warning.

    The old British double base cordite powder used in the .303 Enfield rifles had more nitroglycerin in this powder than many pistol powders have today. And it also caused throat erosion and was banned from machine gun use. And these old Enfield rifles did not go kaboom from using cordite powder.

    I'm wondering if Blue Dot had problems with lighter loads and low pressure or at higher pressures. Powder like 296 have warnings telling you not to load below a given level and detonation. And the old very slow burning Winchester 785 was discontinued due to the same problem with lighter loads.

    Bottom line I would not use Blue Dot for reduced loads in rifle cartridges.
