So Here is all the results if you Boys and Girls want to know more about the 1636 Tube and the Chorongraph feel free to do so, i will answer as best as i can. Thank You
Thank you, Mansell, that is a very good test!
I am surprised at how close the results for 1636 and 2040 tubes are, though I guess it makes sense since in both cases the tube thickness is the same (36-16=20, 40-20=20).
Best regards.
After all i only got a Short 28inch draw so for other shooter that use longer draw the numbers may be different.
My draw is 28-29 inches, too, so to my it applies perfectly.
to Mansell
hi, what bands did you use, I mean it's four-strand or eight-strand?
By my knowledge, 4-strand 2040 or 1636 has no enough power to propel big ammo as 9.5mm or 12mm
Could you show a picture of your bands used?
Here you go mate, on the Left are 1636 Right are 2040 they are both at 15.5cm active and i am using 28inch draw length both of the tubes and the Chorongraph are order from Dankung..
