This spinners works god.
I shot 8 and 10mm ballbering, and there is only a little dent on the spinner.
This is a fine little plinking toy.
But 3 of them,,,, will last fore a lifetime.

I use this little rig fore flatbands to.
Works fine.

(In Swedish)
Den här lilla riggen fungerar även för flatband.
Den är liten och smidig, lätt att ta med över helgen till sommarstugan.
Min gamla rig, som jag gjort själv, är betydligt större och klumpigare.
Att knyta loopade tubband är busenkelt med denna rigg.
Klart värd att investera i.

I have been shooting the amber DK-1632 tubing for a couple of months now and find it to be long lasting and quite versatile. Originally the plan was just to find a sweet BB shooting tube but after some experimenting I found the 1632 capable of shooting everything from .177cal BBs at 5 grains to .44cal lead at 133 grains. It’s all about adjusting the tubing to do what you want.

The 1632 turned out to be a fantastic tube for shooting the light 5-grain (.177cal) BB. A 5 ¾” length with single tubes was found to draw at only 4 pounds at 32" but give enough speed to create some pleasing noise, dents and holes in pop cans at 10-20 yards. This draw weight can be shot all afternoon without fatigue. Most youngsters can even manage this mild weight.

The tiny BB is one of my favourite projectiles but I also enjoy 3/8” steel ammo. The 1632 propels this 54 grain ammo at almost 180 fps when using double tubes cut to an even 6 1/2” length. Perfect for 10m target shooting and plinking! Tests with the red 1632 showed that 200fps is possible with a short 5 1/2" length and my 32" draw. I found this to be about maximum..

The 1632s will even toss a .44cal lead ball with enough smack to drop small-game with appropriate shot placement. At 8 ½ ft-lbs the ball should do considerable damage. The 3/8” lead at 190fps should do the trick too.

My draw length is 32” but sometimes I struggle to get there with the heavier draw weights. The temperature throughout the speed testing was 68-70F. Higher temperatures and longer draw lengths will reward you with even more speed.

--- Amber 1632 ---
Single Tubes (5 ¾” length – 4 lb draw weight)
.177 cal BB = 231 fps
¼” Steel = 200 fps

Pseudo Tapers (6” length, 1 ½” loops – 5 lb draw)
.177cal BB = 252 fps

Double Tubes (6 ½” length – 7 ½ lb draw weight)
3/8” Steel = 178 fps
5/16” Steel = 198 fps
¼” Steel = 212 fps

Four Tubes Per Side (6 5/8” length – 14 ½ lb draw weight)
3/8” Steel = 200 fps
3/8” Lead = 190 fps
.44cal Lead = 170 fps

--- Red 1632 ---
Double Tubes (5 1/2" length)
.177cal BB (5 gr) - 270 fps
1/4" steel (16 gr) - 256 fps
5/16" steel (32 gr) - 232 fps
3/8" steel (54 gr) - 202 fps

As can be seen above, the 1632 tubes have lots of usefulness.... plinking, target shooting, BB shooting, teaching youngsters, and hunting are some examples. This spaghetti tubing is a lot of fun!

Wow, this red 1632 stuff is zippy and the little DanKung BB pouches are a great match. I tested a set of full doubles rigged with 5 1/2" from frame to pouch. My draw length with these tubes is 32" (580% stretch). This set-up zips .177cal BBs at an impressive 270fps! Light draw weight too.. This rig will be perfect for turning pop cans into cylindrical strainers, although the short double tubes are quite overpowered for the BBs. They shoot fast but I could probably do well with pseudo-tapers instead of full loops.

The speed numbers are almost hard to believe. Each ammo weight was tested about 10 times to give accurate numbers.

.177cal BB (5 gr) - 270 fps
1/4" steel (16 gr) - 256 fps
5/16" steel (32 gr) - 232 fps
3/8" steel (54 gr) - 202 fps

The pic shows the 1632s mounted on my DK Black Palm Thunder. The pouches on the side are holding a .177cal BB and 1/4" steel.
