Has anyone done any testing on this to best match tubes to ammo size? When i say 'best' i mean highest FPS.

I shoot face anchor.

Thank in advance. The only tubes i've ever shot were years ago in a fishing bait catapult.

Don't think you'd get a straight answer on that one as its very much personal preference - and how much 'slack', power, use etc. you like in your bands...

Just as a rough guide - for around 30-32" draw and like 480% stretch - though 1632 seems to have a little more than some others.

1632 - 1.77-6mm

2040 - 6mm-9.5mm

1842 - 9.5mm - think this is what you are after if shooting 9.5mm

1745 - 9.5+ (Though for me starts to be a little on the heavy side)

Also its worth mentioning pseudo tapers - can get some good extra speed out of those.

Henry the Hermit did some chrony testing - its somewhere on the forum.

Thanks Matt. Appreciated. I'll get some 2040 to try with 8mm BB's.

How do you achieve pseudo tapers?

I shoot a lot of 3/8" steel, some for target, and some in hunting mode. I use looped Kent #303's are they are very good, but two tubes that really stand out for me are 2040 looped and the new 1842's looped. I have just recently been playing with the New Gen 1842's with a 6.5" active length and a 32.5"+ draw length and I can say without a doubt, it REALLY sends 3/8" steel .. It also REALLY sends 5/8" marbles or 7/16" steel. This stuff is a monster, and would be my go to hunting tube with 3/8' or ammo in the 80-100 gr area !!

2040 is also very, very good and lighter to pull, yet sends 3/8" very well.

Do yourself a favor and get the "New Generation" of either and you will be very happy !!

Hey wll, is the 1842 much lighter to pull and hold than the 1745? Cheers.
