Lovely expansion!

[JaceSpace1369]

JSB KO 10.03gr V3 slugs going 990fps, hit a smaller iguanas broadside at about 23yards and the slug was lodged under the skin on the other side. 1.5" inches of penetration with full expansion and mushrooming!

The last picture measuring the expanded slug I unfolded the corners to measure what the full flat expansion is without the folding of the corners.

Very impressive. That little iguana absorbed lot of energy.

Yes it did!

Impressive expansion! Went fron .177 to .25!

It actually went to .354! That's the most expansion I've seen out of any .177 without fragmenting

That's......CRAZY expansion without fragmenting!

Yessir! I am digging this tune and will be keeping it as is lol.

You have definitely opened my eyes to what a higher powered PCP in .177 can do especially with slugs! Exceptional!

This makes me want to tune my Bullshark back to 10gr slugs

Nice to see the real-world results.

Awesome! I love showing others that .177 works! These slugs are a viable option and at a reasonable price!

Do it, do it, do it! Lol

Yessir, I love it when it happens.

Yep..love these slugs. The CA ground squirrels I've shot with these are a POP and drop. They react as though they've been hit with a much larger projectile..probably because all the energy is transferred inside the target and not in the air/ground beyond.

Got a chance to necropsy a GS after it took a JSB KO 10gr to the back transecting the heart lung area and ending up under the skin between the front legs.

Good weight retention …

And excellent expansion.. 0.312

@JaceSpace1369 ,
what gun are you shooting those JSB KO's out of?

Fx impact m3 500mm liner. I was shooting them at 1070 before but slowed it down for shot to shot consistency and air savings

That is phenomenal weight retention and expansion! How far was the shot?

Chip shot..20yds. Slug started at 1025fps. And according to ChairGun still going around 951 at 20yds with 20.1fpe. The retention may have been better but I had to grab the skin around the slug to make the cut. Kind rough trying to avoid the fleas
