I purchased myself a Bieter plunger. Mainly to learn with. To play with the adjustable spring tension. Until recently, I just screwed a plunger on and shot it as is. I enjoyed the adjustability of the Bieter, adjusting the tension to cause the arrow to go where I am looking. Correcting left or right groups. So I figured the big Bieter was just a tool to figure what I needed and that I would take it off once proper tension is found. At that point, I would use a shorty. Transferring the proper tension by pushing them together, adjusting the shorty until both the Bieter and shorty give equally, thus equilibrium. What I noticed right away is the smoothness of the Bieter over all the others I tried. Hard to go back to the shorty after knowing how much superior the Bieter is. Not only smoother but without any excess play. I would like to find a very short plunger with the quality of the Bieter. Anybody know of one?
