:: The claim was made in the article not me. "In the early 1990s, extensive discussion involving the Jonson design occurred on gun forums like rec.guns and many of the design parameters were shared freely with other gun aficionados" This comes from the article. Further, it was you the cartridge an "invention" not me. As for condemning someone (???) I did not condemn anyone, just an article written by a silly sycophant with numerous issues. Here at the WIki we do not use personal experience or first hand information os I do not have to "play around" with your silly doo-dad. The criteria is that is noteworthy and that it can be referenced reliably.
