I fell in love at first sight on two cartridges, the .22 Hornet and the 7.62x39. I don't know why, so don't ask, I just do. :yingyang:

but it leads me to a question regarding the .22 K-Hornet, which is essentially an A-Square type variant?

aside from higher powder capacity, what other benefits come from having the squared shoulder? what are con's of the squared shoulder?

thanks for your patience and humoring me! :D
 
Longer case life and Lil Gun powder works very well. You can drive it a little faster. I do not think it is any more accurate though.
 
I have owned both the Hornet and the K Hornet. The K definitely gives longer brass life. No matter how careful you are, the standard hornet will separate
cases just above the web. The long, sloping case allows brass to flow forward, and it gets a thin section, which will separate.
I bought a broken case extractor specifically for the problem. The "K", on the other hand does not do this...I was amazed at the case life of the "K", when
compared to the parent case. Of course, the "K" also delivers a bit more velocity because of greater capacity.. Lil'Gun is your friend in any Hornet, BTW.
Both are great chamberings, mild mannered and surprisingly effective within reasonable ranges. Regards, Dave.
 
Brass life might be longer because a cartridge with parallel sides tends to need less trimming, but if fired at higher pressure, the primer pockets will open up faster. I believe that the K-Hornet tends to be more accurate because there is a tendency to seat the bullet with less run-out, and the shorter neck tends to be stiffer, and perhaps less prone to damage. The cons of removing the taper from a cartridge is more difficult extraction should an overload occur; while the powder capacity is small, the Hornet case does require fast burning powders.
 
I don't have a Hornet but I do have one that is similar, the 218 Bee. I was reading an article about the Hornet and K-Hornet a little while back. The writer said the K-Hornet MAY be more accurate because it has more of a shoulder and you can headspace on the shoulder instead of the rim. Some of the brass has variable rim thickness.
 
The Hornet is a great off hand ground hog rifle for farms where you don't want to make a lot of noise. I recall standing in a field with a box of 50 rounds. I shot the entire box. heads kept popping up all around me to see what the noise was.

There are a lot of variations of the 7.62x39, because the case has a big taper. You can blow it out, sharpen the shoulder, and make it a 30 cal. A great use for an old 30 cal barrel that can be set back a couple of inches.

JGS reamers can emial you there list of standard and wildcat reamers, complete with drawings.
 
Besides case life and a tiny bit more velocity, the K-hornet will often shoot quite a bit more accurately than the regular hornet because you set the headspace on the shoulder and not the rim. Unless you have a very uniform batch of cases there is usually enough variation to affect the accuracy.

hey 44, do you have any data showing the K-Hornet being more accurate?
 
Gents, I have had several CZ 527 hornets in the last 15 years and have loaded my cases many times. All were nice and acceptably accurate with 35gr Vmax bullets and 45gr Hornet bullets. I have not noticed any cases coming apart. My K was the least accurate of the quintet I had. FS
