Nope, as is typical for cast bullets, the idea went straight to moulds available for purchase.... One of the reasons for the three base pins is to allow the user to experiment with differrent CG locations (the heavier pellets have the CG further aft).... I would expect like with any other pellets, some guns will like them, and some not so much.... I don't think it will be the number of moulds sold that will determine progress to the .30 cal moulds, but rather feedback on how the .25 cal work.... The designs for the larger calibers are already done.... Next time I am talking to Al, I will ask him when he thinks the .30 cal might be ready for production....Bob
