Have you tried the South Korean Eun Jin pellets? If not, you’re missing out on pellets that really pack a punch!
Great airguns AND great pellets come from South Korea!
In South Korea air rifles are the default weapons for hunting. To make sure hunters have plenty of power, South Korean airgun manufacturers have produced some very accurate and very powerful air rifles. One of these is the Career 707. Made by Shin Sung, the gun’s name was chosen because the word career means “to go very fast.” The gun definitely lives up to that!
The preferred hunting caliber in Korea is .22, although the manufacturers make .177- and .20-caliber guns and have even produced some .25-caliber honkers (primarily for the American market). Are you wondering why hunters who can’t use firearms wouldn’t choose a .25-caliber airgun over a .22? That’s where the Eun Jin pellets come in!
How heavy are these pellets? They’re heavy as…well, lead!
Eun Jin’s .22-caliber pellets are so heavy that they make larger calibers unnecessary! Heavy pellets keep velocities down into the accurate subsonic range (Korean guns are very powerful), so Korean companies make very heavy lead diabolo pellets. The Eun Jin .22 is at the top of the heap, weighing in at 28 grains!
Eun Jin pellets are also heavy even in smaller calibers. The .20-caliber Eun Jin pellet weighs 20.7 grains, compared to the second-closest diabolo – the .20-caliber Beeman Silver Arrow at 15.5 grains. A .177 Eun Jin weighs 16.1 grains. The closest diabolo is the H&N Neue Spitz-Kugeln at 11.57 grains. There’s no comparison!
Eun Jin pellets are available in .25 caliber and 9mm. The Koreans make rifles in these calibers, although they aren’t always available. Right now, the only 9mm on Pyramyd Air’s website is the Career Ultra.
Do you have enough power to shoot Eun Jin pellets?
Heavy pellets are not for average airguns and need lots of thrust to stabilize them in flight. Even though they are a diabolo design, they will not be accurate in guns with less than magnum power. In .22, .25 or .20 caliber, they need a minimum of 40 foot-pounds. In .177 it takes about 25 foot-pounds to stabilize a plump Eun Jin!
If you’ve got the power, Eun Jin is a great pellet to use. Once you’ve used them, you’ll wonder how you ever hunted without them!
I keep noticing the refference to foot-pounds of pressure when talking about the force needed for certian ammo. All airguns I read about are usually rated in mussel fps or I see a refference to calculating foot-pounds with a paticular round.
Do airguns have an “unloaded” foot-pounds of pressure to go by?
I ask because I purchaced a Winchester 1000B from Pyramidair and I cannot find a refference to its foot-pounds.
Wonderfull weapon by the way!
Good question.
In fact, it’s such a good question that I am making it Mondays’ posting.
Thanks,

Glad to help 🙂

I know from your articles that using a pellet that is too heavy for an airgun will reduce its accuracy, but can the gun actually be damaged by using a too-heavy pellet? Just for fun, I was considering experimenting with some really heavy pellets for plinking in a Crossman 2240.
Spring guns can be damaged by too-heavy pellets, because they change the rate of piston closure and can promote piston bounce.
Gas and pneumatics cannot be harmed by heavy pellets, but it is possible for a too-heavy pellet that also fits the bore too tightly to stick in the barrel and exhaust all the air or gas in the gun.
I would try the experiment and see what sort of accuracy you get.

I can tell you from my experience that they are incredibly inaccurate in my Beeman Sportsman.
Something I’d like to add…
Not only are Eun Jin pellets one of the best for PCPs, but if you have a high power gas or pneumatic gun that likes wide skirted pellets,
I would definitely give them a try, because the Eun Jins have a wider skirt than most pellets.
