i've been trying to find an optimal setup for bbs (0.177mm) as frameless for quite some time now.
Even at 1632 (36cm long with microfiber pouch) I feel that the tubes are too strong.
Any tips for me?
If your 36cm length, is the tube length with the pouch tied at each end, a solution may be as easy as cutting a new tube 5 to 8cm longer. If you get the relaxed length down to 1/4th the draw length it will be easier to shoot the bbs that 1/5th the draw length.
If the 36cm means you are shooting butterfly, and drawing to 144cm or longer, you will have to find less powerful latex. Perhaps 2mm solid latex sold for pouch ties. Perhaps thin flats.
