JSB KnockOut Slugs .217 Cal, 25.39gr, Hollowpoint, 200ct

The knock out cal. 217 is the hardest hitting slugs or pellet take I have used in my Beeman Commander. Hitting cans at 100 yards blowing big holes out of back of the can. This is one of the most accurate pellets or slugs that I have shot out of my gun. This gun had over 5000 rounds through with many types of pellets.

Pricy and you need a powerful gun.

Nice case and shape

They would not fIt into my .22 caliber Air Venturi Avenger. They jammed every time I tried to load one as if they were too large. It seems they bulge at the middle.

Unfortunately I received the knock out slugs and winter decided to set in so it might be spring before i try the slugs out here in va.

N/A

Build an indoor range the weather has no affect then

If you know you know. These things fly just as good as their Diablo cousins.. and they weigh the same as the redesigns. With twice the BC* So if your gun pushes a redesigned 25.39gr JSBs at 850 ft./s or more youre in the clear ., this is a wonderful choice for you. They have a pellet back and they are very uniformed and clean. They shoot superb from FX smooth smooth twist X liners. all of them* pellet, slug a, and superior..., light and heavy. They also shoot really well out of my cricket which has a CZ barrel. And they also shoot wonderfully from LW barrels. Choked and unchoked. Long story short this is the best all around slug .217

I rarely say this. But nothing*

Enjoy my favorite slug

the 216 or the 217 shoots the same to me. Maybe it's just my guns, but I cant really tell a difference. Buy two of each and you will get one tin free, and if your gun shoots one better than the other then that would be the ones I would go with. Myself I ill buy 2 of each when I ore-order unless one of the calibers loses its accuracy.

I got 2 tins , one 217 and one 216 , I checked the size 20 slugs from each tin the 216 was all 216 but the 217 there were 16 216 and 4 2165 so i checked more of the 217 and 90 % were 216 , I orderd 2 more 217 and checked them 1 tin was 217 the second tin was 2165 , I checked my gauge and mesured 5 differant weights of 217 H&N slugs and 1 tin of FX slugs and the were all 217 , so my gauge is good so there is a problem with the consistency of JSB slugs

I think the lables were put on wrong tins and one of the machines is making under size slugs at 2165

Remember that saying: If it looks too good to be true, it probably is? The key feature of these slugs is the price: half the cost of FX Hybrids. They are well formed, and well coated (both critical for slugs). They shoot tight groups at closer distances... see below for longer range. They expand, but not as much as Hybrids, more in the range of Hades pellets.

If the hollow point went all the way in, nearly to the tail, then the expansion would be improved, but far more importantly the mass would be closer to the outside, and they would not require a slug liner for long range shooting. As it stands, they will spiral off with longer shots from standard SmoothTwist barrels, unlike Hybrids. Also, one can swap standard pellets, Hades pellets, and Hybrid slugs on the fly; they all zero the same ( With different holdovers at long distances, of course). These do not, shooting (with my Dreamline) a good two inches to the side of where the others zero at 25 yards. Since long range, flexible swapping of ammo, and high expansion are key to me, these fall short, even at the affordable price.

Probably good with classic rifled barrels (with 30+ FPE), as they have a higher twist rate. And good with FX Impacts with high twist rate slug liners. Slug liners are hard to justify on the medium powered Dreamlines, and without them, these are limited in long range accuracy. Also, like any slug, they form hellacious slug-jams, and require drilling them out, not just rodding them out, so be prepared to lose the use of your gun for the day/trip if you double load!

I shoot these out of my old Career 707 RWS Mark 2 twin tube long gun. Shooting them around 825 fps at the muzzle I am getting them to 270 yds with lazer range finder, and hitting a 20 inch steel plate with good consistency with no or light wind. They still hit very hard at that range and mushroom out real flat. Being the old Career has more power on the wheel I would think I could get them out to 350 yds with ease. They are quite amazing slugs.

Not a thing.

Some barrels are more finicky than others. The Career really likes them.

Extra energy at Long range. Able to shoot much further distances than with pellets.

Not a thing.

They mushroom at 270 yds and go through tin siding even at this distance. My old Career 707 RWS II is pushing them at around 825 fps and they still have plenty of energy to make it to 270 yds.

Smooth so they won't hurt your feeding orings.

Nothing

They're accurate with coyote, avenger , not disco, fortitude, maximus, urban, marrauder, at44, or gauntlet.
