I got them form Slingshooting. I wanted to pad out the shipping cost. They were an after thought but I'm glad I got them.Which vendor from China do you get those ?
There is a reduction in speed, of course, because the weight of the bag is comparable to the weight of the projectile. Even if the pouch weighs only 2 grams, it is equal to the weight of an 8 mm steel ball. In the descriptions on various sites came across pouches weighing and 4, and even 6 grams, this is a very large parasitic weight. This is the reason why I never bought them.With the magnet holding the ball is there a small drop off in speed? Any data on this?
Yes but i mean the force of the magnet pulling against the momentum of the bands/ballThere is a reduction in speed, of course, because the weight of the bag is comparable to the weight of the projectile.

I believe that this factor can simply be neglected. The main reason for the speed drop is still the large mass of the pouch.Yes but i mean the force of the magnet pulling against the momentum of the bands/ball
