I spent quite a bit of time gathering chronograph numbers for various band combos and ammo weights for my Pickle Fork Shooters. All shooting was a 28" draw length. The testing was repeated severals times to ensure accuracy.

Notes of interest
- THB = Theraband Black; TBS = Theraband Silver; TBG = Theraband Gold; Tex = .030" Hygenic Latex
- Ammo Weights - Crosman BB = 5 gr; 1/4" steel = 16 gr; 5/16" steel = 32 gr; 3/8" steel = 56 gr
- All bands were adjusted to 7 1/4" from pouch to fork.
- Tex bands and TBG were identical in power. I duplicated the testing several times with all ammo types and the results were always within 1 or 2 fps either way. Possibly one band would excel with heavier pulling bands, heavier ammo or a longer draw length.

Cheers,
Northerner

The chart is in MS-Excel and I'm not sure how to paste the chart into the body of the message. If someone knows how that would be greatly appreciated :)

Good work Norrhner, I have some Sterling 107's and some Flatband .050" latex I will be trying this week. I'll try to expand your results with lead. .310, .375 and .457 dia. Nice job Bud.

Hi Philly,

I'm using your shooting style with the PFS. I anchor just below my right eye (on upper cheek bone). Draw length is around 27 1/2" to 28".

I'm looking forward to your results and I might check some local stores for the 107s.

Cheers,
Northerner

Northner, happy to hear the anchor is working for you, it has really improved my instinctive forks up style of shooting. I got the Sterling 107's from Amazon but had to pay almost as much for shipping. Someone said Staples will order them for you and have them shipped to a local store so no shipping cost. They sell for around $5.00 +/- for a 1 lb box, 50 bands, enough for 25 band sets. I have been shooting them for two days now around 400 shots and no breakage yet. I don't see any negative effect on accuracy. They shoot pretty flat for me out to 25 meters. Give them a try, cheap alternative to custom cuts. I am getting around 153FPS with them at 27 1/2" draw with a working length of 7 1/4", plenty fast enough for target with 3/8 steel with one of my EPS's. As they break I will try a shorter length and recheck the speed but think I might get some hand slap with 3/8 steel.

Philly, want to get more bang for your buck on those 107's?

You have a short draw, so I highly suggest making each band one full set up. That way you get 50 sets in a box. Which should last you forever...

DH and I have been doing it for months, just cut 1 band into 2 parts and set em up on your fork. They'll be a stiffer draw than full length, but they seem to give some great speed.

Even MORE bang for your buck.

Cheers - John

P.S. Don't buy the pale crepe 107's! :lol:

Hi Philly - The 107s seem to be close to 5/8" Theraband Silver with 3/8" ammo and a 27 1/2" draw length. I'll have to check with our local Staples to see if they can get some for me. It's always fun experimenting with various types of bands.

Hi BaneofSmallGame - The pale crepe bands 107s must be what they call "soft stretch for stress-free application". "Latex-free rubber bands" ..." contain no natural rubber proteins and are 100 % latex-free". These don't sound like something for slingshots. I'll ask for the Alliance Sterling 107s.

Hi e-shot - Yup, bamboo looks very nice!

Cheers,
Northerner

I'll have to give that a try John, If I am getting around 150fps at 7 1/4' ish I should do much better with shorter, just wonder about hand slap with 3/8 steel. No problem with my hunting load at .457 I wouldn't think. We shall see, I like them alot. Sending you a pic via PM John.

Notherner...If you check with Alliance`s website and information about the pale crepe gold brand you will find they contain the highest rubber content of all their brands...over 90%...Perry says he uses double bands of this type on some of his slings with success.
