Thank you for the kind words, CR. However, I just noticed you said this, "If I were a Marlin rifleman, I might be a customer just for the fun of it."

The word "customer" stood out to me. To be clear, I am not selling or licensing the cartridge and I am not making anything from it. It is a non-proprietary wildcat - totally non-proprietary. If I've come across like I am promoting it that's only because it's such a great wildcatting option for the Marlin 1895 and Mosin Nagant rifles and I want to share that. Many people own those rifles and have few chambering options for them. But those rifles can be converted to .405 Grenadier very easily. In fact, all it takes for the Marlin 1895 is re-barreling and finishing the chamber.
