My current M193 Clone Data
« on: August 17, 2013, 04:22:03 pm »
With all the appropriate caveats and emphasis on starting 10% lower and working up looking for pressure signs, here is my current M193 clone load data:


M193 equivalent

55gr Hornady fmj bt w/ cannalure
LC 2012 decrimped brass
Trimmed to 1.750"
H-4895 - 25.5gr
Fed 205 primers
OAL - set to crimp midline

3095 fps from 16 barrel

I offer this since I have a lot of H-4895 and it turns out to be under appreciated for use with lighter 5.56/.223 loads.

Group size is at or close to one MOA at 100 yards.

    Hmm.  Have to file this away for later.

    H-4895 is not SUPPOSED to be a top choice for .223.   I thought H=335 and TAC were to be preferred, but I can't get either one locally right now.   They just fly off the shelves before I can get to the store.  I had some H-4895 and saw some decent looking .223 loads for it in the manuals, so thought I'd give it a try.  Never used it before for .223.  Then, some more of that powder showed up in a local store, so I stocked up.

    I'm pleasantly surprised at the velocity and accuracy of this load, which is sort of in the middle of most of the load data (25.0-26.0) in most manuals I have for the Hornady 55gr FMJ.  I reported average velocity on a 10 shot string from a 16 inch barrel.  Might as well round it to 3100 fps.  I failed to mention that the carbine barrel is a standard "government" profile with a 1:9" twist for lighter bullets and is nitrided rather than chrome lined, which could explain the good accuracy, along with my somewhat obsessive case prep technique.

    I'm going to try the same recipe with some 53 grain Barnes TSX bullets, but start at 25.0 and work up.   Barnes load data says max is where I am right now for the FMJ M193 clone, so I'm going to do the right thing, back off a bit, work up gradually and see how it does with those bullets compared to the FMJ in the above load. 

    I did load some 53gr. TXS in the same cases yesterday, with same prep and 25.0 grains of powder.  I'll shoot for accuracy, velocity and pressure next weekend, weather permitting.  I was surprised to see that Barnes recommends H-4895 as the most accurate powder for that bullet. That should make a nice HD load.

    IllinoisThere’s a story about a turtle and a scorpion. Scorpion is stranded on a river bank. Turtle sees this and asks Scorpion to get on his back and he’ll take him across the river. Scorpion gets on Turtle’s back and they go into the river. When they’re about halfway across, Scorpion stings Turtle. As Turtle is sinking, knowing they’re both going to die, he asks Scorpion "Why did you sting me, we’re both going to die?" and Scorpion says "It’s not my fault; it’s what I am."

      Dad's been using 4895 for awhile with 55 softpoints. Okay plinking load for P-dogs.

    COL will be 2.220" with that particular bullet seated to the middle of the cannalure on a freshly trimmed case to 1.750" minimum.
